9 Attach the cable at least 18 inches

(45 cm) away from the discharged bat- tery, but not near engine parts that move. To avoid an arc which could det- onate the hydrogen gas around the bat- tery, the final connection must be at least 18” from the battery.

10 Start the vehicle with the good battery

and run the engine for a while.

11 Try to start the vehicle with the dis-

charged battery. If it does not start after a few tries, it probably needs service.

12 Remove the cables in reverse order to prevent electrical shorting. Take care that they do not touch each other or any other metal.

WARNING

Using a match or flame of any kind near a battery can cause battery gas to explode. You can suffer burns or be blinded. Use a flashlight if you need more light. Be sure the battery has enough water. The battery installed in your new Saab has filler caps. Be sure the right amount of water is there. Add distilled or boiled water if the level is too low. If you don’t, explosive gas could be present. Be sure the electrolyte in the battery is not frozen. Discharged batteries will freeze. When connecting jumper cables to a frozen battery, gas from the chemical reaction inside the battery can build up under the ice and cause an explosion. Battery fluid contains acid that can burn you. Do not get it on you. If you acciden- tally get it in your eyes or on your skin, flush the area with water and get medical help immediately.

5 Check that the jumper cables do not

have loose or missing insulation. If they do, you could get a shock and also the vehicles could be damaged. Before you connect the cables, here are some basic things you should know. Positive (+) will go to positive (+) and negative (-) will go to a major metal engine part with a good ground. Do not connect (+) to (-) or you will get a short that could injure you or would damage the battery and maybe other parts as well.

6 Connect the red positive (+) cable to the positive (+) terminal of the vehicle with the discharged battery.

7 Do not let the other end touch metal.

Connect it to the positive (+) terminal of the good battery. Use a remote positive (+) terminal if the vehicle has one.

8 Now connect the black negative (-)

cable to the good battery’s negative ter- minal.

WARNING

Do not let the other end touch anything until the next step. The other end of the negative cable does not go to the dead battery. It goes to a major metal part with a good ground on the engine of the vehi- cle with the discharged battery.

Driving considerations with compact spare wheel/tire fitted

WARNING

Do not exceed 50 mph (80 km/h) as the tire can overheat and adversely affect the handling of the car. The tire should be inflated to 60 psi (420 kPa).

The following should be observed when the compact spare wheel (T115/70 R16) is installed: The compact spare is light and easy to handle when changing the wheel. Do not drive farther than necessary with the com- pact spare fitted – the maximum life of the wheel is only just over 2000 miles (3,500 km). Have the standard wheel repaired and reinstalled as soon as possi- ble.

Points to bear in mind when driving with a compact spare wheel: (cid:127) The car’s ground clearance is reduced

with the compact spare fitted.

(cid:127) Only one compact spare wheel may be

used at any time.

(cid:127) Take care not to hit the curb. (cid:127) Do not fit snow chains. (cid:127) Leave the wheel cover off, so that the

warning text is readily visible.

NOTE

To avoid damaging a punctured alloy wheel this can be placed outside up in the spare-wheel well but only while driving to the closest dealer. A general rule is that all heavy loads must be well secured in the luggage compart- ment, see page 142.

For long trips Before starting off on a long journey, it is advisable to have your car inspected by your Saab dealer. Obtain a few important items to take along on your journey such as spare bulbs, wiper blades, fuses, a Poly-V belt and the like. You can check some points yourself before- hand: (cid:127) Make sure that the engine is in good con-

dition.

(cid:127) Check that no oil or fuel leaks out of the

engine or gearbox/transmission.

(cid:127) Check the coolant and power steering

fluid levels. Check also for leaks. Inspect the Poly-V belt and replace it if it shows any signs of wear. (cid:127) Check the battery charge. (cid:127) Check the tires for tread pattern and air pressure, including the compact spare wheel.

(cid:127) Take an extra car key/remote control and

keep it separate, see also page 36.

(cid:127) Check the brakes. (cid:127) Check all bulbs. (cid:127) Check for the presence of the tool kit and

the jack in the car.

Engine The engine is a transverse four-cylinder in-line engine with twin overhead camshafts and 16 valves. The engine is equipped with two balance shafts that reduce engine vibration to a min- mimum. The balance shafts are chain-driven and rotate at twice the speed of the crankshaft. They produce forces and torques that are opposed to those generated by the pistons and connecting rods. The effect occurs twice in each revolution of the engine, coun- teracting the vibration from its moving parts, and at the same time reducing unwanted engine noise. The gearbox, located on the right (viewed from the front), is integrated with the engine.

Engine families Saab cars imported into the United States and Canada meet all applicable emission control standards. The engine family and appropriate tune-up specifications are iden- tified on a label affixed to the left front inner fender. These engine families meet applicable EPA Federal Standards, California State Stan- dards and Canadian Federal Standards and are equipped with the following systems: • Sequential multiport fuel injection system. (cid:127) Three way catalytic converter. (cid:127) Crankcase emissions control system. (cid:127) Evaporative emission system.

Emission control systems The systems for controlling emissions to the atmosphere require regular checking and adjustment at the intervals specified in the service program. In addition to meeting the exhaust emission regulations and thereby helping to keep the environment clean, a correctly tuned engine will also give maximum fuel economy.

NOTE

The Trionic engine management system continuously monitors the operation of these systems and has on-board diag- nostic capabilities (OBD II). If the CHECK ENGINE light in the main instrument illu- minates, the Trionic ECM has detected a problem. The car will continue to operate, but performance may be diminished. You should have your car checked by a Saab dealer as soon as possible.

Car care

189

ORVR (Onboard Refueling Vapor Recovery) All hydrocarbons formed when refueling will be recovered by the car and not released into the atmosphere. The hydrocarbons are absorbed in an evaporative emission canis- ter. When the engine is subsequently started, the evaporative emission canister is gradually purged as air is sucked into it through a shut-off valve. The hydrocar- bon/air mixture passes through the evap canister purge valve and into the engine where it is burned. "Refueling", see page 151. When refueling, make sure you screw the filler cap on and keep turning until it has clicked at least 3 times. Otherwise, it is pos- sible for the CHECK ENGINE light to illumi- nate and a TIGHTEN FUEL FILLER CAP message to appear on SID.

Saab Trionic engine management system The Saab Trionic engine management system is a unique Saab development that combines sequential multiport fuel injection, electronic distributorless ignition and turbo- charger boost pressure control into one sys- tem. The Trionic engine control module (ECM) monitors many different engine parameters such as:

Intake manifold pressure. Intake air temperature.

(cid:127) Crankshaft position. (cid:127) Engine coolant temperature. (cid:127) Throttle position. (cid:127) The oxygen content of the exhaust gases. The ECM receives information regarding engine knocking from a sophisticated feed- back function in the ignition discharge unit. By processing all of this information, the Tri- onic system can control fuel injector open- ing duration, ignition timing and turbo- charger boost pressure to provide excellent engine performance while maintaining low emissions and fuel consumption.

Engine oil Checking the fluid level Regularly check the oil level in the engine. Do this with the car standing on level ground with the engine warm, 2-5 minutes after it has been turned off. Take the dipstick out and wipe it off with a clean rag before carry- ing out the check. The level must not be below the MIN mark on the dipstick, but nor should it be above the MAX mark. Excess engine oil could result in abnormal oil consumption. The distance between MIN and MAX corre- sponds to a volume of about one quart. When necessary, add oil of the recom- mended grade via the dipstick pipe. Make sure that the cap of the dipstick is screwed on properly after the check. Oil changing The engine oil must be changed in accor- dance with the service program. Oil volume and grade, see page 237. Oil changing should be carried out on a warm engine.

Oil filler cap and dipstick

Drain plug

1 Unscrew the drain plug in the bottom of the sump and leave the oil to drain into an oil tray or other suitable receptacle for at least ten minutes. Take care, as the oil may be hot.

2 After the oil has been drained, unscrew

and remove the oil filter.

3 Fit a new filter and tighten it by hand. 4 Refit the drain plug with a new washer. 5 Add new oil.

Run the engine to normal temperature and check the oil level.

NOTE

Change of engine oil and oil filter may be required more frequently (5000-mile intervals (8,000 km)) if any one of the fol- lowing conditions apply to the car:

(cid:127) Most trips are less than 5 to 10 miles (8 to 16 km). This is particularly important when outside temperatures are below freezing.

(cid:127) Most trips include extensive idling

(such as frequent stop-and-go driving).

(cid:127) Most trips are through dusty areas.

(cid:127) You frequenty tow a trailer or use a car-

rier on top of your vehicle.

If the vehicle is used for delivery ser- vice, police, taxi or other commerical applications.

WARNING

MAX +80°

(cid:127) Prolonged and repeated exposure of the skin to engine oil can cause seri- ous skin disorders.

(cid:127) Avoid prolonged skin contact when-

ever possible. Wash the affected area thoroughly with soap and water after any contact.

(cid:127) Keep oil out of reach of children.

(cid:127) Do not touch the turbocharger or

manifold. These get very hot when the engine has been running.

(cid:127) Do not spill oil on hot parts of the

engine as this could cause a fire. Used engine oil is particularly flammable.

(cid:127) Protect the environment. Do not dis- pose of oil in the ground or down a drain. Dispose of all used oil and oil fil- ters at an appropriate disposal facility.

+80° MIN

Oil dipstick, automatic transmission

Transmission fluid Manual transmission Check and top up the fluid in accordance with the service program. If original fluid cannot be obtained for top- ping up, Dextron III (synthetic fluid) auto- matic transmission fluid can be used. If so, the car should be taken to an authorized Saab dealer as soon as possible to have the reason for low fluid level corrected and orig- inal fluid installed. Automatic transmission Check the fluid level as follows: 1 Park the car on level ground and apply the parking brake. The automatic trans- mission fluid must be at normal running temperature, approximately 175°F

(cid:127) 192

Car care

(80°C). This can be achieved by driving the car for about 30 min on the open road.

2 With the engine idling, move the selector

lever to D and wait for at least 15 seconds. Next, move the selector lever to R and wait for 15 seconds again. Finally, move the selector lever to P. Let the engine idle.

3 Wipe the dipstick clean with a lint-free

cloth and put it back.

4 With the fluid at normal temperature, the

level should be between the MAX and MIN marks on the dipstick. Top up, as necessary, with Texaco Texamatic Dex- tron III automatic-transmission fluid, adding it through the dipstick pipe. The distance between the MIN and MAX marks on the dipstick corresponds to a volume of approximately 0.4 qts (0.4 litre).

NOTE

If there is a burnt smell or the fluid is black, change the fluid as soon as possible.

If the outside temperature is below 50°F (10°C), the fluid will not reach the specified temperature of 175°F (80°C). In this case, the correct fluid level may be 0.8 in (20 mm) below the MAX mark.

Coolant

WARNING

(cid:127) Proceed with caution if the radiator is

boiling when you open the hood. Never remove the expansion-tank filler cap when the radiator is boiling. Loosen the cap carefully, and let the engine cool before removing the cap.

(cid:127) The cooling system is pressurized – hot coolant and vapor can escape when the filler cap is released.

(cid:127) Exercise care when adding coolant.

Coolant on hot surfaces constitutes a fire risk.

The expansion tank is transparent, to facili- tate checking. The level must be a little under the mark ”KALT – COLD” on the tank when the engine is cold. If the SID message "FILL COOLANT FLUID" is displayed, the level in the expansion tank should be checked. Top up as necessary with equal parts of clean water and coolant. Use only coolant approved by Saab. If the expansion tank is empty when coolant is added, run the engine to normal temper- ature and top up again, as necessary.

Coolant expansion tank

Coolant The cooling system is filled at the factory with coolant containing a 50% concentra- tion of a combined antifreeze and corrosion inhibitor. A weaker mixture will result in reduced anticorrosion protection. For pro- tection against freezing in very cold weather, a stronger concentration will be needed. A 60% concentration of antifreeze will pro- vide protection at temperatures down to -58 F (-50°C).

Car care

193

Air filter

WARNING

Only use an air filter recommended by Saab Automobile AB.

The coolant does not normally have to be changed during the service life of the car. This type of coolant has a reddish colour and should not be mixed with other types of coolant. Saab Original coolant should be used all year round. Only use coolant approved by Saab.

NOTE

Always mix the antifreeze with the appropriate volume of water before adding it to the cooling system. If pure antifreeze is added, the engine could still freeze and be damaged. This is because the antifreeze will not mix properly with the coolant before the thermostat has opened to allow full circulation.

Brake pad wear indicators The outboard brake pads on the front wheels incorporate pad-wear indicators. When the lining is down to 0.11 in (3 mm), the pad will produce a screeching, squeal- ing or scraping noise when the brakes are applied. New pads should be installed with- out delay. Brake pads should only be changed by an authorized Saab dealer. To ensure optimum brake performance, use only Saab original brake pads.

Car care

194
Brake- clutch fluid and brake pads

WARNING

Brake fluid deteriorates as it becomes old. Because it is hygroscopic, it absorbs water from the air and, in time, could allow vapor to form in the brake system, thus reducing its performance. It is therefore important that brake fluid be changed reg- ularly, as specified in the service pro- gram.

Checking the fluid level The combined brake and clutch-fluid reser- voir is transparent to facilitate checking of the fluid level. The level should be between the MAX and MIN marks. Top up, as necessary, with DOT 4 fluid. Do not use DOT 5 brake fluid. Use only new brake fluid from a sealed con- tainer. Check that there are no leaks in the brake system. Changing of the brake fluid should be carried out by an authorized Saab dealer.

The vehicle´s regular braking system is adjusted automatically, but the parking brake has to be adjusted manually. This work, involving adjustment of the parking brake cables and brake pads, must only be carried out by an authorized Saab dealer. It is not possible to detect, through abnormal pedal or parking brake-lever travel, whether brake pads are worn and need replacing. It is therefore essential that brake pads be checked regularly, as specified in the ser- vice program..

NOTE

Avoid spilling brake fluid onto paintwork, since it can cause the paint to bubble and lift. If any brake fluid is spilled, the area should be flushed with large quantities of water as quickly as possible.

Power steering fluid reservoir

Car care

195

Battery

WARNING

(cid:127) Work on the battery may entail an

explosion hazard, since the battery gives off hydrogen which forms an explosive mixture with the oxygen in the air. For this reason, always avoid sparks or open flames when working near the battery.

(cid:127) The battery contains corrosive sulphu- ric acid. Always wear a face mask or goggles when working on the battery.

(cid:127) If battery acid gets into the eyes or

splashes the skin or clothing, wash the affected area liberally with water. If acid gets into the eyes or a large quantity makes contact with the skin, seek medical help.

Power steering

WARNING

Do not fill the power steering fluid to above the MAX mark. Too much fluid can result in leakage. Power steering fluid on hot engine com- ponents constitutes a fire risk.

Check the level of the power-steering fluid in the reservoir regularly, in accordance with the service program. The wheels should point forward during the check. Clean around the cap before it is unscrewed. Unscrew the cap and wipe the dipstick. To check the fluid level, first screw the cap on fully again and then remove. The level should be between the MAX and MIN marks on the dipstick when the oil temperature is about 68°F (+20°C). If the oil is colder the oil level can be lower, and in higher tempera- tures the level can be higher, both of which are acceptable. Top up with power-steering fluid CHF 11S (part number 8996860).

196

Car care

A car with standard equipment and a fully charged battery can be left for up to 40 days and still have a sufficient charge for starting. If extra equipment is fitted, such as a mobile telephone, the time may be reduced to about 15 days. Always connect the positive (red) cable to the positive (+) terminal of the battery and the negative (blue) cable to its negative (-) terminal. Always disconnect both battery leads when boost charging the battery.

NOTE

• Don’t connect the battery terminals

+ and – the wrong way around.

(cid:127) Serious damage can occur to the car’s electrical system if a battery or alterna- tor lead is disconnected while the engine is running.

Correct fluid level in the battery

Taking out the battery

The liquid level in the car battery must be checked at regular intervals.

NOTE

NOTE

Never use tap water to top up the battery. Use distilled or boiled water.

Tap water contains salts and minerals that accelerate the corrosion of the battery elec- trodes, which can shorten the life of the bat- tery. The charge level should be checked with a battery-acid tester. The specific gravity of the acid in a fully charged battery should be 1.28. A specific gravity of 1.18 roughly indi- cates a 50% charge.

A discharged battery can freeze and frac- ture. Batteries should therefore always be stored away from frost.

If frequent short journeys are made in cold weather, the battery may need to be given a booster charge. This can be done either using a battery charger or by taking the car for a long drive.

Drive belt

WARNING

Car care

197

(cid:127) Keep hands and clothing clear of drive

belts when engine is running. (cid:127) Always stop the engine before

inspecting drive belts.

(cid:127) The fan can start even when the

engine is switched off.

NOTE

Drive belt

Serious damage can occur to the car’s electrical system if an alternator lead is disconnected while the engine is running.

The alternator is situated on the right-hand side of the engine. It is driven via a poly-V belt from the crankshaft pulley. The poly-V-belt also drives the water pump, the A/C compressor and the steering servo pump. The belt tension is critical, and is adjusted by an automatic belt tensioner. See also page 61, "Warning charging".

Car care

198
Wipers and washers Wiper blades Check and clean all wiper blades regularly. We recommend Saab washer fluid for cleaning. If poor wiper performance is experienced, clean the windshield with Saab washer fluid. This is particularly important if the car has been through an automatic car wash, as this sometimes leave a wax coating on the wind- shield. If wiper performance is still unsatisfactory, fit new blades.

WARNING

Take care not to spill washer fluid concen- trate onto hot surfaces as this constitutes a fire hazard.

Windshield and rear window 1 Push the catch in (1). 2 Pull the complete wiper blade down-

wards so that it comes away from the wiper arm. Slide the entire blade out from the arm.

Headlight wipers 1 Lift the wiper arm off the headlight. 2 Detach the wiper blade by pulling it

laterally from the wiper arm.

3 Fit the new blade by sliding it into the

retainer on the wiper arm and pressing it firmly home.

Car care

199

Washer jets The washer jets, which are adjustable, can be cleaned with a pin if necessary. The jet for rear-window washing is located in the right-hand part of the high-mounted brake light.

Washer-fluid reservoir

Washer The reservoir holds 5 quarts (4.7 litres). When the SID message "WASHER FLUID LEVEL LOW" appears there is about 1.5 quarts (1.4 litres) left. Fill with quality washer fluid, available from your Saab dealer and follow the instructions on the package to reduce the risk of freez- ing. Note: If the reservoir is run dry and the car has a rear-window wiper, then after refilling you cannot wash the rear window until you have first washed the windscreen.

Tool for changing fuses

WARNING

To avoid the risk of short-circuiting and/or fire breaking out in the electrical system, the following advice should be heeded: (cid:127) Always consult an authorized Saab

dealer before modifying or adding any electrical equipment. Failure to do so can result in the electrical system being damaged.

(cid:127) Never replace a fuse with one having a

higher/lower rating than specified (see page 208). The color of the fuse indicates its amperage.

(cid:127) If the same fuse blows repeatedly,

have the electrical system checked by an authorized Saab dealer.

(cid:127) If a MAXI fuse blows, it means that

there is a major fault in the electrical system. Have the car checked without delay by an authorized Saab dealer.

Car care

206
Fuses The fuses are housed in two fuse panels: one at the end of the instrument panel on the driver’s side, and one under the hood. To check if a fuse has blown, first remove it from the panel (see below). If the filament is broken, the fuse has blown. A special tool for removing fuses is provided at the bottom of the fuse panel on the fascia. Simply push the tool onto the fuse, squeeze and remove the fuse.

The DICE and TWICE control modules are linked to a data bus, which is basically an information carrier that allows information to be exchanged between all the control mod- ules and components connected to the bus. If a fault occurs in any of these components, diagnostic faults codes are set in the rele- vant control module, which enhances fault diagnosis at the Saab dealer. The scan tool connector for fault diagnosis is located under the instrument panel on the driver’s side.

DICE / TWICE DICE = Dashboard Integrated Central Elec- tronics TWICE = Theft-Warning Central Electronics DICE and TWICE are electronic control modules. DICE controls, among other things: (cid:127) Front lights and interior lighting.

MAXI fuse for soft-top system (Convertible)

MAXI fuses The MAXI fuses are housed in the fuse box under the hood. These fuses can be checked in the same way as the other fuses. The MAXI fuses are designed to protect the car’s electrical system from being dam- aged. Each MAXI fuse protects a number of electrical circuits and functions and there- fore has a higher rating (amperage) than the standard fuses. No spare MAXI fuses are supplied with the car.

NOTE

If a MAXI fuse blows, it means that there is a major fault in the electrical system. Have the car checked without delay by an authorized Saab dealer.

Wheels Alternative wheels and tires If you wish to fit other tires or wheels than those supplied with the car, consult your Saab dealer first as to the possibilities avail- able. Wheels/tires combinations that are not approved by Saab can negatively affect the car´s directional stability, steering and brak- ing in both wet and dry conditions. Do not assume that a wheel/tire combina- tion will function properly just because it will bolt on. To ensure that the speedometer is as accu- rate as possible it should be reprogrammed if wheels of a different dimension are fitted. Contact an authorized Saab dealer.

NOTE

For wide wheels and/or low-profile tires, bear in mind the following: (cid:127) Tires and wheels can be damaged in

potholes etc.

(cid:127) Springs, shock absorbers and wheel

bearings and body mountings can be overloaded.

(cid:127) The wheels can come into contact with

chassis and body components.

(cid:127) The speed and load limits for the tires must not be exceeded; see page 212.

(cid:127) Wheels larger than 17” must not be fitted on the Saab 9-3. For Viggen models the wheel should not be larger than 17”. The maximum permissible offset for the 9-3 is 49 mm and for the Viggen 42 mm.

(cid:127) Wheels smaller than 16” must not be

fitted on Viggen models. Fitting a smaller size wheel on a Viggen is not possible due to the size of the brake discs.

The wheels and tires have been carefully matched to the characteristics of the car and play a key role in its outstanding roadhold- ing and handling.

Tire pressure

NOTE

Check the tire pressures at least once per month. Underinflation is the main cause of: (cid:127) Tires wearing out prematurely. (cid:127) Damage to the sidewalls. (cid:127) Damage to the wheels.

Tires need to be inflated to suit the load car- ried and the maximum speed the car will be driven (see the recommended tire pres- sures on the back cover). Tire pressure label, see page 243. Note that all values apply to cold tires. For tires with an aspect ratio less than /60, increase the tire pressure by 3 psi (20 kPa) for rough roads with potholes to minimize the risk of rim damage. Never reduce the pressure of a hot tire. If the tires are hot when you check them, only increase the pressure, if necessary. Soft tires will cause faster wear than over-pressurized tires. They also increase fuel consumption. If a valve is leaking, simply unscrew it and fit a new one. Important! Remember to adjust the tire pressures if you change the load in the car or intend to cruise at a substantially higher or lower speed than normal.

Car care

Rotating the tires

WARNING

When fitting just one new pair of tires, these should be fitted to the rear wheels, as these are more critical to the direc- tional stability of the car (e.g. on braking or in a skid). The existing rear tires should therefore be moved to the front. Always move left rear to left front and right rear to right front, so that the direction of rotation remains the same.

Because of front wheel drive, the front tires tend to wear faster than the rear ones. New tires should always be fitted in pairs, so that tires on the same axle have the same amount of tread. The wheels should be marked, L (left) and R (right), when changing between summer and winter (snow) tires. This ensures that the direction of rotation of the wheels is the same when they are refitted. Fit the tires in best condition to the rear wheels. Store wheels lying flat or hanging – never standing upright.

Tire markings An example of the meaning of the different markings in a tire size is given below for a tire size of 205/55 R16 91V:

205 Tire section width, mm 55 Aspect ratio, i.e. the section height

is 60 % of the section width

V Tire approved for speeds up to

150 mph (240 km/h)

W Tire approved for speeds up to

Winter tires Winter (snow) tires are recommended for winter climates where the majority of your driving will be done on snow and ice. Winter tires should be fitted to all four wheels to maintain a proper balance. Your Saab dealer can advise you of to the correct size tire for your car (if different from the original size) and also supply Saab approved winter tires pre-mounted on steel or alloy rims. Tire quality grading (cars sold in U.S.) New tires must be graded and labeled in accordance with new Federal regulations. Standard tests are conducted to measure performance in the areas of traction and temperature resistance. Refer to the tire sidewall for the specific quality grades of the tires provided on your new Saab. Compact spare tires are exempt. DOT QUALITY GRADES (cid:127) Treadwear. (cid:127) Traction AA, A, B, C. (cid:127) Temperature A, B, C. All passenger car tires must conform to Fed- eral safety requirements in addition to these grades.

Uniform Tire Quality Grading (US) Quality grades can be found where applica- ble on the tire sidewall between tread shoul- der and maximum section width. For exam- ple: Treadwear 200 Traction AA Temperature A Treadwear The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tire graded 150 would wear one and one half (1 1/2) times as well on the gov- ernment course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices and differences in road character- istics and climate.

Traction The traction grades, from highest to lowest, are AA, A, B and C. These grades represent the tire’s ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance.

WARNING

The traction grade assigned to a tire is based on straight-ahead braking, traction test and does not include acceleration, cornering, hydroplaning or peak traction characteristics.

Car care

213

Temperature The temperature grades are A (the highest), B, and C, representing the tire’s resistance to the generation of heat and its ability to dis- sipate heat when tested under controlled conditions on a specified indoor laboratory test wheel. Sustained high temperature can cause the material of the tire to degenerate and reduce tire life. Excessive temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades B and A represent higher levels of performance on the laboratory test wheel than the minimum required by law.

WARNING

The temperature grade for a tire is estab- lished for a tire that is properly inflated and not overloaded. Excessive speed, underinflation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire fail- ure.

Date code

Wear indicators

Date code Tires should be regarded as perishable goods. As the tires age, the rubber becomes progressively harder, and the roadholding ability of the tires diminishes. This is partic- ularly true on winter tires. Tires now have a date-code marking for the year of manufacture. The first two digits denote the week number and the last two digits the year. The ”<” symbol points to the year. Accordingly, a date code of 0200 signifies that the tire was manufactured in week 02, 2000.

Wear indicators The tires incorporate wear indicators in the form of smooth, treadless strips across the width, which become visible when only 2/32" (1.6 mm) of tread remains. As soon as the indicators become visible, new tires should be fitted without delay. Make sure you are familiar with the legal limit for minimum tread depth in your country and also any regulations gov- erning the use of winter (snow) tires.

Spare wheel (under the carpet in the trunk)

Compact spare wheel The compact spare is light and easy to handle when changing the wheel. Its use is only permitted when a standard tire has sus- tained a puncture. The maximum life of the tire is only 2000 miles (3,500 km). Do not exceed 50 mph (80 km/h) with the compact spare fitted. The compact spare should be inflated to 60 psi (420 kPa). Carry the punctured tire in the spare-wheel well under the trunk floor. Have the standard tire repaired and refitted as soon as possible Driving considerations with compact spare wheel/tire fitted, see page 184. The spare wheel, the tools and the jack with its crank are carried under a panel in the trunk.

Car care

215

(cid:127) Stow the jack in the place provided for

it under the panel in the floor of the trunk. Secure it properly to avoid injury to passengers in the event of a crash.

(cid:127) Do not use the jack for any purpose

other than for jacking up the car.

(cid:127) If light-alloy wheels have been fitted to the car for several years and a change is made to steel wheels, the threads for the wheel bolts in the brake discs should be cleaned before the thinner steel wheels are fitted. The innermost threads in the holes may be clogged with sand, salt and rust so that the cor- rect tightening torque cannot be achieved.

Changing a wheel

WARNING

(cid:127) The car jack is designed solely for use

in changing a wheel or fitting snow chains. It must not be used to support the car during repair work or servicing.
