Wear comfortable clothing and shoes you can easily drive in. [s your vehicle ready for a long trip? If you keep it serviced and maintained, it’s ready to go. If it needs service, have it done before starting out. Of course, you’ll find experienced and able service experts in Geo dealerships all across North America. They’ll be ready and willing to help if you need it. Here are some things you can check before a trip:
Windshield Washer Fluid: Is the reservoir full? Are all windows clean inside and outside?
Freeway Driving
Mile for mile, freeways (also called thruways, parkways, expressways, turnpikes, or superhighways) are the safest of all roads. But they have their own special rules. The most important advice on freeway driving is: Keep up with traffic and keep to the right. Drive at the same speed most of the other drivers are driving. Too-fast or too-slow driving breaks a smooth traffic flow. Treat the left lane on a freeway as a passing lane. At the entrance there is usually a ramp that leads to the freeway. If you have a clear view of the freeway as you drive along the entrance ramp, you should . . .I20
sleepy. Don’t let it happen to you! If it does, your vehicle can leave the road in less than a second, and you could crash and be injured. What can you do about highway hypnosis? First, be aware that it can happen. Then here are some tips: 0 Make sure your vehicle is well
ventilated, with a comfortably cool interior.
0 Keep your eyes moving. Scan the road ahead and to the sides. Check your mirrors and your instruments frequently.
0 If you get sleepy, pull off the road into
a rest, service, or parking area and take a nap, get some exercise, or both. For safety, treat drowsiness on the highway as an emergency.
Wiper Blades: Are they in good shape? Fuel, Engine Oil, Other Fluids: Have you checked all levels? Lights: Are they all working? Are the lenses clean? Tires: They are vitally important to a safe, trouble-free trip. Is the tread good enough for long-distance driving? Are the tires all inflated to the recommended pressure? Weather Forecasts: What’s the weather outlook along your route? Should you delay your trip a short time to avoid a major storm system? Maps: Do you have up-to-date maps?
Highway Hypnosis Is there actually such a condition as “highway hypnosis”? Or is it just plain falling asleep at the wheel? Call it highway hypnosis, lack of awareness, or whatever. There is something about an easy stretch of road with the same scenery, along with the hum of the tires on the road, the drone of the engine, and the rush of the wind against the vehicle that can make you
Hill and Mountain Roads
Driving on steep hills or mountains is different from driving in flat or rolling terrain. If you drive regularly in steep country, or if you’re planning to visit there, here are some tips that can make your trips safer and more enjoyable. (See “Off-Road Driving” in the Index for information about driving off-road.)
Keep your vehicle in good shape. Check all fluid levels and also the brakes, tires, cooling system and transmission. These parts can work hard on mountain roads.

own lane when driving
Know how to go uphill. You may want to shift down to a lower gear. The lower gears help cool your engine and transmission. and you can climb the hill better. Stay in y o ~ ~ r on two-lane roads i n hills or mountains. Don’t swing wide or cut ~tcross [he center of the road. Drive at speeds that let you stay in your own lane. As you go over the top of a h i l l . be alert. There could be something in your lane. like a stalled car or an accident. You n~ay see highway signs on mountains that warn of special problems. Examples are long grades, passing or no-passing zones, a falling rocks area, or winding roads. Be alert to these and take appropriate action.
Your Driving and the Road 0 Know how to go down hills. The mosl
t 0
important thing to know is this: let your engine do some of the slowing down. Shift to a lower gear when you go down a steep or long hill.

If you don’t shift down, your brakes could get so hot that they wouldn’t work well. You would then have poor braking or even none going down a hill. You could crash. Shift down to let your engine assist your brakes on a steep downhill slope.
A CAUTION:
Coasting downhill in “N” (Neutral) or with the ignition off is dangerous. Your brakes will have to do all the work of slowing down. They could get so hot that they wouldn’t work well. You could crash. Always have your engine running and your vehicle in gear when you go downhill.
. . .122
Winter Driving
Here are some tips for winter driving: Have your Geo in good shape for winter. Be sure your engine coolant mix is correct. You may want to put winter emergency supplies in your vehicle.
Include an ice scraper7 a small brush or broom. a supply of windshield washer fluid, a rag, some winter outer clothing, a small shovel, a flashlight, a red cloth, and a couple of reflective warning triangles. And, i f you will be driving under severe conditions, include :I small bag of sand, ;I piece of old carpet or a couple of burlap bags to help provide traction. Be sure yo11 properl}, secure these item i n your vehicle.
Driving on Snow or Ice Most o f the time. those placcs where your tires meet the road probably have good traction. Howe\w-. it’ thcrc is snow or ice between your tires antl the road, you can Iwve ;I very slippery situation. You‘ll have ;t l o t less traction or “grip“ and will need to be very careful. What‘s the worst time for this’? “Wet ice.” Very cold snow or ice can be slick and hurd t o drive on. Rut wet ice can be even more trouble because it nlay offer the least traction o f a l l . You can get ”wet ice” when it’s about freezing (32°F; 0°C) and freezing rain begins to f a l l . Try to avoid hiving on wet ice until salt and sand :rews can get there.
Whatever the condition - smooth ice. packed. blowing or loose snow - drive with caution. Accelerate gently. Try not to break the fragile traction. If you accelerate too fast, the drive wheels will spin and polish the surface under the tires even more. Your anti-lock brakes improve your ability t o make a hard stop on a slippery road. Even though you have an anti-lock braking system. you’ll want to begin stopping sooner than you would on dry pavement. See “Anti-lock” i n the Index. Allow greater following distance on any slippery road. Watch for slippery spots. The road might be fine until you h i t H spot that’s covered with ice. On an otherwise clear road. ice patches may appear in shaded areas where the sun can’t reach: around clumps of trees. behind buildings, or under bridges. Sometimes the surftlce of a curve or an overpass may remain icy when the surrounding roads are clear. If you see a patch of ice ahead of you, brake before you are on it. Try not to brake while you’re actually on the ice, and avoid sudden steerins maneuvers.

Your Driving and the Road
If You’re Caught in a Blizzard If you are stopped by heavy snow, you could be in a serious situation. You should probably stay with your vehicle unless you know for sure that you are near help and you can hike through the snow. Here are some things to do to summon help and keep yourself and your passengers safe: Turn on your hazard flashers. Tie a red cloth to your vehicle to alert police that you’ve been stopped by the snow. Put on extra clothing or wrap a blanket around you. If you have no blankets or extra clothing, make body insulators from newspapers, burlap bags, rags, floor mats - anything you can wrap around yourself or tuck under your clothing to keep warm. You can run the engine to keep warm, but be careful. . . ,124
Run your engine only as long as you must. This saves fuel. When you run the engine, make it go a little faster than just idle. That is, push the accelerator slightly. This uses less fuel for the heat that you get and it keeps the battery charged. You will need a well-charged battery to restart the vehicle, and possibly for signaling later on with your headlights. Let the heater run for awhile. Then, shut the engine off and close the window almost all the way to preserve the heat. Start the engine again and repeat this only when you feel really uncomfortable from the cold. But do it as little as possible. Preserve the fuel as long 3s you can. To help keep warm, you can get out of the vehicle and do some fairly vigorous exercises every half hour or so until help comes.
Towing a Trailer
NOTICE: Pulling a trailer improperly can dam- age your vehicle and result in costly repairs not covered by your warranty, To pull a trailer correctly, follow the advice in this section, and see your Geo dealer for important information about towing a trailer with your vehicle.
Your vehicle can tow a trailer. To identify what the vehicle trailering capacity is for your vehicle, you should read the information in “Weight of the Trailer” that appears later in this section. But trailering is different than just driving your vehicle by itself. Trailering means changes in handling, durability, and fuel economy. Successful, safe trailering takes correct equipment, and it has to be used properly. That’s the reason for this section. In it are many time-tested, important trailering tips and safety rules. Many of these are important for your safety and that of your passengers. So please read this section carefully before you pull a trailer. Load-pulling components such as the engine, transmission, wheel assemblies, and tires are forced to work harder against the drag of the added weight. The engine is required to operate at relatively higher speeds and under greater loads, generating extra heat. What’s more, the trailer adds considerably to wind resistance, increasing the pulling requirements.
If You Do Decide to Pull a Trailer If you do, here are some important points. There are many different laws having to do with trailering. Make sure your rig will be legal, not only where you live but also where you’ll be driving. A good source for this information can be state or provincial police. Consider using a sway control. You can ask a hitch dealer about sway controls. Don’t tow a trailer at all during the first 500 miles (800 km) your new vehicle is driven. Your engine, axle or other parts could be damaged. Then, during the first 500 miles (800 km) that you tow a trailer, don’t drive over 50 mph (80 km/h) and don’t make starts at full throttle. This helps your engine and other parts of your vehicle wear in at the heavier loads.
125 ...
Your Driving and the Road Three important considerations have to do with weight:
Weight of the Trailer How heavy can a trailer safely be? It should never weigh more than 1,000 pounds (450 kg), But even that can be too heavy. It depends on how you plan to use your rig. For example, speed, altitude, road grades, outside temperature and how much your vehicle is used to pull a trailer are all important. And, it can also depend on any special equipment that you have on your vehicle. You can ask your dealer for our trailering information or advice, or you can write us at:
Customer Assistance Department Chevrolet/Geo P.O. Box 7047 Troy, MI 48007-7047
In Canada, write to:
General Motors of Canada Limited Customer Assistance Center 1908 Colonel Sam Drive Oshawa, Ontario L1H 8P7
. . ,126
Weight of the Trailer Tongue The tongue load (A) of any trailer is an important weight to measure because it affects the total or gross weight of your vehicle. The gross vehicle weight (GVW includes the curb weight of the vehicle, any cargo you may carry in it, and the people who will be riding in the vehicle. And if you will tow a trailer, you must add the tongue load to the GVW because your vehicle will be carrying that weight, too. See “Loading Your Vehicle” in the Index for more information about your vehicle’s maximum load capacity. If you’re using a “dead-weight” hitch, the trailer tongue (A) should weigh 10% of the total loaded trailer weight (B). If you have a “weight-distributing” hitch, the
:railer tongue (A) should weigh 12% of ;he total loaded trailer weight (B). After you’ve loaded your trailer, weigh the trailer and then the tongue, separately, to see if the weights are proper. If they uen’t, you may be able to get them right simply by moving some items around in the trailer.
Total Weight on Your Vehicle’s Tires Be sure your vehicle’s tires are inflated to the limit for cold tires. You’ll find these numbers on the Certification label at the rear edge of the driver’s door or see “Tire Loading” in the Index. Then be sure you don’t go over the GVW limit for your vehicle.
Hitches It’s important to have the correct hitch equipment. Crosswinds, large trucks going by, and rough roads are a few reasons why you’ll need the right hitch. Here are some rules to follow: 0 If you use a step bumper hitch, and your trailer tongue has a V-shaped foot, your bumper could be damaged in sharp turns. Check the distance from the front edge of the foot to the middle of the hitch ball socket. If the
0
distance is less than 12 inches, take the foot off the trailer tongue. Will you have to make any holes in the body of your vehicle when you install a trailer hitch? If you do, then be sure t o seal the holes later when you remove the hitch. If you don't seal them, deadly carbon monoxide (CO) from your exhaust can get into your vehicle (see "Carbon Monoxide" in the Index). Dirt and water can, too.
Safety Chains You should always attach chains between your vehicle and your trailer. Cross the safety chains under the tongue of the trailer so that the tongue will not drop to the road if it becomes separated from the hitch. Instructions about safety chains may be provided by the hitch manufacturer or by the trailer manufacturer. Follow the manufacturer's recommendation for attaching safety chains. Always leave just enough slack so you can turn with pour rig. And, never allow safety chains to drag on the ground.
Trailer Brakes If your trailer weighs more than 1,000 pounds (450 kg) loaded, then it needs its
they must be adequate. own brakes -and Be sure t o read and follow the instructions for the trailer brakes so you'll be able to install, ad-just and maintain them properly.
Don't tap into your vehicle's brake system if the trailer's brake system will use more than 0.02 cubic inch (0.3 cc) of fluid from your vehicle's master cylinder. If it does. both systems won't work well. You could even lose your brakes. Will the trailer brake parts take 3,000 psi (20 650 kPa) of pressure? If not, the trailer brake system must not be used with your vehicle. If everything checks out this far. then make the brake fluid tap at the port on the master cylinder that sends fluid to the rear brakes. But don't use copper tubing for this. If you do, it will bend and finally break off. Use steel brake tubing.
Driving with a Trailer Towing a trailer requires a certain amount of experience. Before setting out for the open road, you'll want to get to know your rig. Acquaint yourself with the feel of handling and braking with the added weight of the trailer. And always keep in
mind that the vehicle you are driving is now a good deal longer and not nearly so responsive as your vehicle is by itself. Before you start, check the trailer hitch and platform. safety chains, electrical contwxtor. lights, tires and mirror adjustment. If the trailer has electric brakes, start your vehicle and trailer moving and then apply the trailer brake controller by hand to be sure the brakes are working. This lets you check your electrical connection at the same time. During your trip, check occasionally to be sure that the load is secure. and that the lights and any trailer brakes are still working.
Following Distance Stay at least twice as far behind the vehicle ahead as you would when driving your vehicle without a trailer. This can help you avoid situations that require heavy braking and sudden turns.
Passing You'll need more passing distance up ahead when you're towing a tnliler. And. because you're B good deal longer, you'll need to go much farther beyond the
127 ...
Your Driving and the Road passed vehicle before vou can return to your lane.
Backing Up Hold the bottom of the steering wheel with one hand. Then, to move the trailer to the left, just move that hand to the left. To move the trailer to the right, move your hand to the right. Always back up slowly and, if possible, have someone guide you.
Making Turns When you’re turning with a trailer, make wider turns than normal. Do this so your trailer won’t strike soft shoulders, curbs, road signs, trees, or other objects. Avoid jerky or sudden maneuvers. Signal well in advance.
Turn Signals When Towing a Trailer When you tow a trailer, your vehicle has to have a different turn signal flasher and extra wiring. The green arrows on your instrument panel will flash whenever you signal a turn or lane change. Properly hooked up, the trailer lights will also flash, telling other drivers you’re about to turn, change lanes or stop. . .-’ . 1 28
When towing a trailer, the green arrows on your instrument panel will flash for turns even if the bulbs on the trailer are burned out. Thus, you may think drivers behind you are seeing your signal when they are not. It’s important to check occasionally to be sure the trailer bulbs are still working.
Driving on Grades Reduce speed and shift to a lower gear before you start down a long or steep downgrade. If you don’t shift down, you might have to use your brakes so much that they would get hot and no longer work well. On a long uphill grade, shift down and reduce your speed to around 45 mph (70 km/h) to reduce the possibility of engine and transmission overheating. If you are towing a trailer and you have a manual transmission with fifth gear, you may prefer not to use fifth gear. Just drive in fourth gear (or, as you need to, .a lower gear).
Parking on Hills You really should not park your vehicle, with a trailer attached, on a hill. If something goes wrong, your rig could
start to move. People can be injured, and both your vehicle and the trailer can be damaged. But if you ever have to park your rig on a hill, here’s how to do it: 1. Apply your regular brakes, but don’t shift into “F’” (Park) yet, or into gear for a manual transmission.
2. Have someone place chocks under the
trailer wheels.
3. When the wheel chocks are in place, release the regular brakes until the chocks absorb the load.
4. Reapply the regular brakes. Then
apply your parking brake, and then shift to ‘T” (Park), or “R” (Reverse) for a manual transmission.
5. If you have a four-wheel-drive
vehicle, be sure the transfer case is in a drive gear - not in “N” (Neutral).
6. Release the regular brakes.
2. Let up on the brake pedal. 3. Drive slowly until the trailer is clear
of the chocks.
4. Stop and have someone pick up and
store the chocks.
Maintenance When Trailer Towing Your vehicle will need service more often when you're pulling a trailer. See the Maintenance Schedule for more on this. rhings that are especially important in :railer operation are automatic .ransmission lluid (don't overfill), engine oil? axle lubricant, belts, cooling system, and brake adjustment. Each of these is covered in this manual, and the Index will help you find them quickly. If you're trailering, it's a good idea to review these sections before you start your trip. Check periodically to see that all hitch nuts and bolts are tight.
When You Are Ready to Leave after Parking on a Hill 1. Apply your regular brakes and hold
the pedal down while you:
Start your engine; Shift into a gear; and
0 Release the parking brake.

Jump Starting
If your battery has run down, you may want to use another vehicle and some jumper cables to start your Geo. But please follow the steps below to do it safely.
NOTICE: Ignoring these steps could result in costly damage to your vehicle that wouldn’t be covered by your war- ranty. Trying to start your Geo by pushing or pulling it could damage your vehicle, even if you have a manual transmission. And if you have an automatic transmission, it won’t start that way.
To Jump Start Your Geo: 1. Check the other vehicle. It must have
a 12-volt battery with a negative ground system. NOTICE:
If the other system isn’t a 12-volt system with a negative ground, both vehicles can be damaged.
2. Get the vehicles close enough so the jumper cables can reach, but be sure the vehicles aren’t touching each other. If they are, it could cause a ground connection you don’t want. You wouldn’t be able to start your Geo, and the bad grounding could damage the electrical systems.
3. Turn off the ignition on both vehicles. Turn off all lights that aren’t needed, and radios. This will avoid sparks and help save both batteries. And it could save your radio!
I NOTICE: I If you leave your radio on, it could be
badly damaged. The repairs wouldn’t be covered by your warranty.

Towing Your Vehicle
Try to have a GM dealer or a professional towing service tow your Geo. The usual towing equipment is a sling-type ( A ) or a wheel-lift (B) or car carrier (C) tow truck. If your vehicle has been changed or modified since it was factory-new by adding aftermarket items like fog lamps, aero skirting, or special tires and wheels, these instructions and illustrations may not be correct. Before you do anything, turn on the hazard warning flashers. When you call, tell the towing service:
A dolly must be used when towing from the front.
G
A CAUTION:
To help avoid injury to you or others:
Never let passengers ride in a vehicle that is being towed. Never tow faster than safe or posted speeds. Never tow with damaged parts not fully secured. Never get under your vehicle after it has been lifted by the tow truck. Always use seperate safety chains on each side when towing a vehicle. Never use T-hooks. Use “J” hooks instead.
i.
When your vehicle is being towed, have the ignition key off. The steering wheel should be clamped in a straight-ahead position, with a clamping device designed for towing service. Do not use the vehicle’s steering column lock for this. The transmi.ssion and transfer case, if you have one, should be in “Neutral” and the parking brake released. Don’t have your vehicle towed with the rear wheels in contact with the ground. If a vehicle must be towed from the front with sling-type or wheel lift equipment, the rear wheels must be supported on a dolly. If your vehicle has four-wheel drive, don’t have it towed on the front wheels unless you must. If a vehicle with four-wheel drive must be towed on the front wheels, set your tnanual, freewheeling hubs to “FREE” or unlock your automatic freewheeling hubs, and set your transfer case to two-wheel drive. If your vehicle must be towed on the front wheels, don‘t go more than 55 rnph (90 km/h).

If No Steam Is Coming from Your
Engine:
If you get the overheat warning but see or
hear no steam, the problem may not be
too serious. Sometimes the engine can get
a little too hot when you:
0 Climb a long hill on a hot day.
0 Stop after high speed driving.
Idle for long periods in traffic.
Tow a trailer.
If you get the overheat warning with no
sign of steam, try this for a minute or so:

warning, you can drive. Just to be safe,
drive slower for about ten minutes. If the
warning doesn’t come back on, you can
drive normally.
If the warning continues, pull over, stop,
and park your vehicle right away.
If there’s still no sign of steam, you can

tank is boiling, don’t do anything else
until it cools down.
The coolant level should be at or above
“FULL.” If it isn’t, you may have a leak
in the radiator hoses, heater hoses,
radiator, water pump or somewhere else
in the cooling system.
I NOTICE:
I Engine damage from running your
engine without coolant isn’t covered
by your warranty.
[f there seems to be no leak, check to see
if the electric engine fan is running. If the
mgine is overheating, the fan should be
running. If it isn’t, your vehicle needs
service.
How to Add Coolant to the Coolant
Recovery Tank
[f you haven’t found a problem yet, but
:he coolant level isn’t at or above the
“FULL” mark, add a 50/50 mixture of
:lean water (preferably distilled) and a
xoper antifreeze at the coolant recovery
:a&. (See “Engine Coolant” in the Index
for more information about the proper
:oolant mix.)

NOTICE:
In cold weather, water can freeze and
crack the engine, radiator, heater core
and other parts. Use the recom-
mended coolant.
When the coolant in the coolant recovery
tank is at or above the "FULL" mark.
start your vehicle.
If the overheat warning continues, there's
ope more thing you can try. You can add
the proper coolant m i x directly to the
radiator, but be sure the coolink 7 . 4: y. stem
is cool before you do it.
A CAUTION:
Steam and scalding liquids from a
hot cooling system can blow out and
burn you badly. They are under pres-
sure, and if you turn the radiator
pressure cap - even a little - they can
come out at high speed. Never turn
the cap when the cooling system,
including the radiator pressure cap, is
hot. Wait for the cooling system and
radiator pressure cap to cool if you
ever have to turn the pressure cap.

2. Then keep turning the pressure cap,
but now push down a s you turn it.
Remove the pressure cap.
3. Fill the radiator with the proper mix,
up to the base of the filler neck.
How to Add Coolant to the Radiator
1. You can remove the radiator pressure
cap when the cooling system,
including the radiator pressure cap an(
upper radiator hose, is no longer hot.
Turn the pressure cap slowly to the
left until it first stops. (Don’t press
down while turning the pressure cap.)
If you hear a hiss, wait for that to stop
A hiss means there is still some
pressure left.

4. Then fill the coolant recovery tank to
the "FULL" murk.
Put the cap back on the coolant
recovery tank, but leave the radiator
pressure cap off.
6.
Start the engine and let it run until
you can feel the upper radiator hose
getting hot. Watch out for the engine
fan.
By this time, the coolant level inside
the radiator filler neck may be lower.
If the level is lower, add more of the
proper m i x through the filler neck
until the level reaches the base of the
filler neck.

Changing a Flat Tire
If a tire goes tlat, avoid further tire and
wheel damage by driving slowly to a
level place. Turn on your hazard warning
flashers.
Problems on the Road
If a Tire Goes Flat
It’s unusual for a tire to “blow out” while
you’re driving, especially if you maintain
your tires properly. If air goes out of a
tire, it’s much more likely to leak out
slowly. But if you should ever have a
“blowout.” here are a few tips about what
to expect and what to do:
If a front tire Fails, the flat tire will create
a drag that pulls the vehicle toward that
side. Tdke your foot off the accelerator
pedal and grip the steering wheel firmly.
Steer to maintain lane position, then
gently brake to a stop well out of the
traffic lane.
A rear blowout, particularly on a curve,
acts much like a skid and may require the
same correction you’d use in a skid. In
any rear blowout, remove your foot from
the accelerator pedal. Get the vehicle
under control by steering the way you
want the vehicle to go. It rnay be very
bumpy and noisy, but you can still steer.
fently brake to a stop, well off the road
if possible.
If a tire goes tlat, the next section shows
how to use your jacking equipment to
:hange a tlat tire safely.
7, Then replace the pressure cap. At any
time during this procedure, if coolant
begins to flow out of the filler neck,
reinstall the pressure cap. Be sure the
arrows on the pressure cap line up like
this.

A CAUTION:
.v ,
Changing a tire can cause an injury. The vehicle can slip off the jack and roll
over you or other people. You and they could be badly injured. Find a level
place to change your tire. To help prevent the vehicle from moving:
1. Set the parking brake firmly.
2. Put an automatic transmission shift lever in T“ (Park), or shift a manual

gear - not in “ N ’ (Neutral).
4. Turn off the engine.
To be even more certain the vehicle won’t move, you can put chocks at the front
and rear of the tire farthest away from the one being changed. That would be the
tire on the other side of the vehicle, at the opposite end.
The following steps will tell you how to

If You’re Stuck: In
Sand, Mud, Ice or
Snow
What you don’t want to do when your
vehicle is stuck is to spin your wheels.
The method known as “rocking” can
help you get out when you’re stuck, but
you must use caution.
153 ...
Problems on the Road
NOTICE:
Spinning your wheels can destroy
parts of your vehicle as well as the
tires. If you spin the wheels too fast
while shifting your transmission back
and forth, you can destroy your trans-
mission.
Rocking your vehicle to get it out:
First, turn your steering wheel left and
right. That will clear the area around your
front wheels. Then shift back and forth
between “R” (Reverse) and a forward
gear (or with a manual transmission,
between First or Second gear and
Reverse), spinning the wheels as little as
possible. Release the accelerator pedal
while you shift, and press lightly on the
accelerator pedal when the transmission is
in gear. If that doesn’t get you out after a
few tries, you may need to be towed out.
Or, you can use your recovery hooks, if
your vehicle has them. If you do need to
be towed out, see “Towing Your Vehicle”
in the Index.
. . I154
Using the Recovery Hooks
If you ever get stuck in sand, mud, ice or
snow, your Tracker is equipped with
recovery hooks. The recovery hooks are
provided at the front and rear of your
vehicle. You may need to use them if
you’re stuck off-road and need to be
pulled to some place where you can
continue driving.
NOTICE:
Never use the recovery hooks to tow
the vehicle. Your Tracker could be
darnaged and it would not be covered
by warranty.

F YOU want to do some of your own
ervice work, you’ll want to get the

mch more about how to service your
;eo than this manual can. To order the
. . .I56
NOTICE:
If you try to do your own service
work without knowing enough about
it, your vehicle could be damaged.
Fuel
Use regular unleaded gasoline rated at 87
octane or higher. It should meet
specifications ASTM D4814 in the U.S.
and CGSB 3.5-92 in Canada. These fuels
should have the proper additives, so you
should not have to add anything to the
fuel.
In the U.S. and Canada, it’s easy to be
sure you get the right kind of gasoline
(unleaded). You’ll see “UNLEADED”
right on the pump. And only unleaded
nozzles will fit into your vehicle’s filler
neck.
Be sure the posted octane is at least 87. If
the octane is less than 87, you may get a
heavy knocking noise when you drive. If
it’s bad enough, it can damage your
engine.
If you’re using fuel rated at 87 octane or
higher and you still hear heavy knocking,
your engine needs service. But don’t
worry if you hear a little pinging noise
when you’re accelerating or driving up a
hill. That’s normal and you don’t have to
buy a higher octane fuel to get rid of
pinging. It’s the heavy, constant knock
that means you have a problem.
What about gasoline with blending
materials that contain oxygen
(oxygenates), such as MTBE or alcohol?
MTBE is “methyl tertiary-butyl ether.”
Fuel that is no more than 15% MTBE is
fine for your vehicle.
Ethanol is ethyl or grain alcohol.
Properly-blended fuel that is no more
than 10% ethanol is fine for your vehicle.
Methanol is methyl or wood alcohol.
NOTICE:
Fuel that is more than S% methanol
is bad for your vehicle. Don’t use it.
It can corrode metal parts in your fuel
system and also damage plastic and
rubber parts. That damage wouldn’t
be covered under your warranty. And
even at 5% or less, there must be
“cosolvents” and corrosion prevent-
ers in this fuel to help avoid these
problems.
Gasolines for Cleaner Air
Your use of gasoline with deposit control
additives will help prevent deposits from
forming in your engine and fuel system.
That helps keep your engine in tune and
your emission control system working
properly. It’s good for your vehicle, and
you’ll be doing your part for cleaner air.
Many gasolines are now blended with
oxygenates. General Motors recommends
that you use gasolines with these blending
materials, such as MTBE and ethanol. By
doing so, you can help clean the air,
especially in those parts of the country
that have high carbon monoxide levels.
In addition, some gasoline suppliers are
now producing reformulated gasolines.
These gasolines are specially designed to
reduce vehicle emissions. General Motors
recommends that you use reformulated
gasoline. By doing so, you can help clean
the air, especially in those parts of the
country that have high ozone levels.
You should ask your service station
operators if their gasolines contain deposit
control additives and oxygenates, and if
they have been reformulated to reduce
vehicle emissions.
Fuels in Foreign Countries
If you plan on driving in another country
outside the U.S. or Canada, unleaded fuel
may be hard to find. Do not use leaded
gasoline. If you use even one tankful,
your emission controls won’t work well
or at all. With continuous use, spark plugs
can get fouled, the exhaust system can
corrode, and your engine oil can
deteriorate quickly. Your vehicle’s oxygen
sensor will be damaged. All of that means
costly repairs that wouldn’t be covered by
your warranty.
To check on fuel availability, ask an auto
club, or contact a major oil company that
does business in the country where you’ll
be driving.
You can also write us at the following
address for advice. Just tell us where
you’re going and give your Vehicle

Engine Oil
It’s a good idea to check your engine oil
level every time you get fuel. In order to
get an accurate reading, the oil must be
warm and the vehicle must be on level
ground.
Turn off the engine and give the oil a few
minutes to drain back into the oil pan. If
you don’t, the oil dipstick might not show
the actual level.
To Check Engine Oil
Pull out the dipstick and clean it with a
paper towel or cloth, then push it back in
all the way. Remove it again, keeping the
tip lower.

When to Add Oil:
If the oil is at or below the ADD mark,
you’ll need to add some oil. But you must
use the right kind. This section explains
what kind of oil to use. For crankcase
capacity, see “Capacities and
Specifications” in the Index.
NOTICE:
Donl add too tnuch oil. If your
engine has so much oil that the o i l
level gets above the upper mark that
shows the proper operating range,
your engine could be damaged.
What Kind of Oil to Use
Beginning midyear 1993, oils of the
proper quality for your vehicle will be
identified with this new “starburst”
symbol. The “starburst” symbol indicates
that the oil has been certified by the
American Petroleum Institute (API), and
is preferred for use in your gasoline
engine.
You should look for this on the front of
the oil container, and use o&
oils that
display this new symbol.
You should also use the proper viscosity
oil for your vehicle, as shown in the
following chart:
163 ...
Service and Appearance Care

Grade Engine Oils
For best fuel economy and cold starting,
select the lowest SAE viscosity grade oil
for the expected temperature range.

MAY BE USED AT TEMPERATURES ABOVE
40 DEGREES F (4 DEGREES C).
DO NOT USE SAE 1OW-40, SAE 2OW-50 OR
ANY OTHER GRAOE OIL NOT RECOMMENDED.
. . .164
As shown in the chart, SAE SW-30 is best
for your vehicle. However, you can use
SAE IOW-30 if it’s going to be 0°F
(-1 8°C) or above. These numbers on an
oil container show its viscosity, or
thickness. Do not use other viscosity oils,
such as SAE IOW-40 or SAE 2OW-SO.
If you cannot find oils with the new
“starburst” symbol on the front of the
container, you should look for and use
oils containing the following three things:
Ski or SG
“SH” or “SG” must be on the oil
container, either by itself or combined
with other quality designations, such
as “SHKD,” “SH,SG,CD,” “SGKD,”
etc. These letters show American
Petroleum Institute (API) levels of
quality.
SAE SW-30
Energy Conserving I1
Oils with these words on the container
will help you save fuel.
These three things are usually included in
1 doughnut shaped logo (symbol) on most
Zontainers. If you cannot find oils with the
“starburst” symbol, you should look for
lils with the doughnut shaped symbol,
;.ontaining the three things noted above.
NOTICE:
If you use oils that do not have either
the “starburst” symbol or an API SH
or SG designation, you can cause
engine damage not covered by your
warranty.
3 M Goodwrench” oil (in Canada, GM
Engine Oil) meets all the requirements
[or your vehicle.
Engine Oil Additives
Don’t add anything to your oil. Your Geo
dealer is ready to advise if you think
something should be added.
When to Change Engine Oil
See if any one of these is true for you:
Most trips are less than 4 miles (6 km).
It’s below freezing outside and most
trips are less than 10 miles ( 1 6 km).
The engine is at low speed most of the
time (as in door-to-door delivery, or
stop-and-go traffic).
You tow a trailer often.
Most trips are through dusty places.
The vehicle is frequently operated
off-road.
If any one of these is true for your
vehicle, then you need to change your
and filter every 3,000 miles (5 000 km) or
3 months - whichever comes first.
If none of them is true, change oil and
filter every 7,500 miles (1 2 500 km) or
7.5 months - whichever comes first.
Engine Coolant Heater (Engine Block
Heater)
An engine coolant heater can be a big
help if you have to park outside in very
cold weather, 0°F (-I 8°C) or colder. If
your vehicle has this option, see “Engine
Coolant Heater” in the Index.
What to Do with Used Oil
Did you know that used engine oil
contains elements that may be unhealthy
for your skin and could even cause
cancer? Don’t let used oil stay on your
skin for very long. Clean your skin and
nails with soap and water, or a good hand
cleaner. Wash or properly throw away
clothing or rags containing used engine
oil. (See the manufacturer’s warnings
about the use and disposal of oil products.)
Used oil can be a real threat to the
environment. If you change your own oil,
be sure to drain all free-tlowing oil from
the filter before disposal. Don’t ever
dispose of oil by putting it in the trash,
pouring it on the ground, into sewers, or
into streams or bodies of water. Instead.
recycle it by taking it to a place that
collects used o i l . If you have a problem
properly disposing. of your used oil, ask
your dealer, a service station or a local
recycling center for help.
Air Cleaner
Refer to the Maintenance Schedule to
detertnine when to replace the air filter.
See “Scheduled Maintenance Services“ ir
the Index. A CAUTION:
Operating the engine with the air
cleaner off can cause you or others to
be burned. The air cleaner not only.
cleans the air, it stops flame if the
engine backfires. If it isn’t there, and
the engine backfires, you could be
burned. Don’t drive with it off, and
be careful working on the engine
with the air cleaner off.

When to Check and Change
A good time to check your automatic
transmission fluid level is when the
engine oil is changed. Refer to the
Maintenance Schedule to determine when
to change your fluid. See “Scheduled
Maintenance Services” in the Index.
How to Check
Because this operation can be a little
difficult, you may choose to have this
done at your Geo dealership Service
Department.
If you do it yourself, be sure to follow all
the instructions here, or you could get a
false reading on the dipstick.
NOTICE:
Too much or too little tluid can
damage your transmission. Too much
can mean that some of the fluid could
come out and fall on hot engine parts
or exhaust system parts, starting a fire.
Be sure to get an accurate reading if
you check your transmission tluid.
Wait at least 30 minutes before checking
the transmission fluid level if you have
been driving:
0 When outside temperatures are above
90°F (32°C).
0 At high speed for quite a while.
In heavy traffic - especially in hot
weather.
While pulling a trailer.
To get the right reading, the fluid should
be at normal operating temperature,
which is 180°F to 200°F (82°C to 93°C).
To check transmission fluid hot: Get the
vehicle warmed up by driving about IS
miles (24 km) when outside temperatures
are above 50°F ( 10°C). If it’s colder than
50°F (IOOC), drive the vehicle in “D”
(Third Gear) until the engine temperature
gage moves and then remains steady for
ten minutes. Then follow the hot check
procedures.
To check transmission fluid cold: A cold
check is made after the vehicle has been
sitting for eight hours or more with the
engine off and i s used only as a reference.
Let the engine run a t idle for five minutes
if outside temperatures are 50°F (10°C)
or more. If it’s colder than 50°F (IO’C),
you may have to idle the engine longer.

take much fluid, generally less than a pint.
Don’t overfill. We recommend you use
only fluid labeled DEXRON@-III or
DEXRON@-IIE, because fluids with that
label are made especially for your
automatic transmission. Dama e caused
by fluid other than DEXRON 8 -m or
DEXRON@-IIE is not covered by your

0 After adding fluid, recheck the fluid
level as described under “How to
Check.”
When the correct fluid level is
obtained, push the dipstick back in
all the way.

2. Push it back in all the way, wait three
seconds and then pull it back out
again.

3. Check both sides of the dipstick, and
read the lower level. The fluid level
must be in the “COLD’ area for a
cold check or in the “HOT” area or
cross-hatched area for a hot check.
4. If the fluid level is in the acceptable
range, push the dipstick back in all
the way.
How to Add Fluid
Refer to the Maintenance Schedule to
determine what kind of transmission fluid
to use. See “Recommended Fluids and
Lubricants” in the Index.
[f the fluid level is low, add only enough
of the proper fluid to bring the level up to
the “COLD” area for a cold check or the
“HOT” area for a hot check. It doesn’t
If you do it yourself, be sure to follow all
the instructions here, or you could get a
false reading.
NOTICE:
Too much or too little fluid can
darnage your transmission. Too much
can mean that some of the tluid could
come out and Pall on hot engine parts
or exhaust system parts, starting a
fire. Be sure to get an accurate read-
ing if you check your transmission
fluid.
Check the fluid level only when your
engine is off, the vehicle is parked on a
level place and the transmission is cool
enough for you to rest your fingers on the
transmission case.
Then, follow these steps:
1. Remove the filler plug.
2. Check that the lubricant level is up to
the bottom of the filler plug hole.
3. If the fluid level is good, install the
plug and be sure it is fully seated. If
the fluid level is low, add more fluid
as described in the next steps.
How to Add Fluid:
Here’s how to add tluid. Refer t o the
Maintenance Schedule to determine what
kind of tluid t o use. See “Recommended
Fluids and Lubricants” in the Index.
1. Rernove the filler plug.
2. Add tluid at the filler plug hole. Add
only enough fluid to bring the fluid
level LIP to the bottom of the filler
plug hole.
3. Install the filler plug. Be sure the plug
is fully seated.
CIutch Adjustment
The clutch linkage in your vehicle
should be checked as recommended in
your Maintenance Schedule. To check,
push the clutch pedal down with your
hand until you feel some resistance to
movement of the pedal. If the pedal
moves freely up to an inch (25 mm) or
so before you feel resistance to the travel,
adjustment isn’t needed.
If there is no free travel or very little
(less than S/8 of an inch), see your dealer
for adjustment.
