2003 Saab 9 3 Owners Manual

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

three way catalytic converter

(cid:127) crankcase emissions control system (cid:127) evaporative emission system.

173

Car care 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.

(cid:127) 174

Car care

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.

NOTICE

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

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 hydrocarbon/ air mixture passes through the evap canis- ter purge valve and into the engine where it is burned. "Refueling", see page 128. When refueling, make sure you screw the filler cap on and keep turning until it has clicked 1 time. Otherwise, it is possible for the Engine malfunction (CHECK ENGINE) light to illuminate. The following message will appear on the SID:

Tighten fuel filler cap.

Engine oil Checking the oil level Check the engine oil level regularly. 1 Park the car on a level ground. 2 Switch off the engine and wait for

2–5 minutes. The engine should be at normal operating temperature.

3 Take the dipstick out and wipe it off with

a clean rag before carrying 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. If the oil level is too low, the following mes- sage will be displayed on the SID:

Low engine oil level. Fill oil now.

Oil filler cap and dipstick

The distance between the MIN and MAX marks is equivalent to 1.0 qt (1.0 l). Top up as necessary with oil of the recom- mended grade (see page 238). Make sure you screw on the oil filler cap properly after topping up the oil to avoid run- ning problems.

NOTICE

Too high oil level can damage the engine.

During the Break-in Period (approx. 3,000 miles or 5,000 km) and when driving at high speeds or with a trailer, the oil con- sumption may be higher than normal.

NOTICE

Change of engine oil and oil filter may be required more frequently if the car is being used under certain conditions, see page 231.

Car care

177

Engine oil and oil filter should be changed according to the service program. For oil volumes and grades, refer to "Tech- nical data". The oil should be drained when the engine is warm. The car must stand on level ground. 1 Unscrew the drain plug in the bottom of the sump and leave the oil to drain into a suitable receptacle for at least 10 minutes. Take care, as the oil may be hot.

2 Refit the drain plug with a new washer. 3 Change the oil filter once the engine oil

has drained (see page 178).

4 Fill with new oil. Run the engine to normal temperature and check the oil level.

WARNING

(cid:127) Prolonged and repeated exposure of the skin to engine oil can cause seri- ous skin disorders. The risk of cancer cannot be ruled out.

(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

exhaust 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

dispose of oil into the ground or down a drain. Dispose of all used oil and oil filters at an appropriate disposal facility.

178

Car care

Changing filter 1 Unscrew the oil filter cap. (cid:127) Lift the cap slightly and carefully pry apart the cap and the filter housing.

(cid:127) Remove the filter cap. 2 Remove the filter. Have paper towelling

or a rag at hand to catch the oil that escapes from the filter.

3 Fit a new filter. 4 Check the seal in the cap. Apply a small amount of new engine oil to the O-ring. 5 Screw on the cap. The correct tightening

torque is 25 Nm (18 lbf ft).

179

The expansion tank is transparent to facili- tate checking the coolant level. When the engine is cold, the coolant must not lie above the KALT/COLD mark on the expansion tank (boundary between the upper and lower sections of the tank, see illustration). Top up with a mixture of equal parts of Saab-approved antifreeze and clean water. If the expansion tank is empty when coolant is added, run the engine to normal temper- ature and top up again, as necessary.

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. (cid:127) The cooling system is pressurized – hot coolant and vapor can escape when the filler cap is released. These can cause injury to your eyes and burns. Loosen the cap carefully, and let the engine cool before removing the cap.

(cid:127) Exercise care when adding coolant.

Coolant on hot surfaces constitutes a fire risk.

If the coolant level drops too low, the follow- ing message appears on the SID:

Coolant level low. Refill.

Coolant expansion tank

The properties of the coolant are retained for the entire service life of the car. There- fore, it is not necessary to change the cool- ant. The coolant contains 50 % antifreeze and anti-corrosion fluid. This ratio gives the best cooling effect. Lower concentrations should be avoided, in view of the corrosion risk. Other makes of antifreeze can damage the engine and cooling system.

180

Car care

NOTICE

If the cooling system needs topping up, mix the antifreeze with the appropriate quantity of drinking water or distilled water before adding it to the system. If undiluted 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 ther- mostat has opened to allow full circula- tion.

Note: If incorrect coolant is used or added, the life- time properties will be affected. Even if the coolant is flushed from the system and replaced with life-time coolant, life-time properties are no longer retained and the coolant must then be drained and replaced at regular intervals.

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 regularly, as specified in the service program.

Checking Brake fluid should be changed according to the service program. Refer to the Warranty and Service Book. The brake and clutch fluid reservoir is trans- parent to facilitate checking of the fluid level. The fluid level should lie between the MAX and MIN marks. Top up as necessary with DOT 4 brake fluid. Do not use DOT 5 fluid. Use only new brake fluid from a sealed container. The brake fluid level will fall somewhat as the brake pads wear. The MAX level in the reservoir corresponds to the amount of brake fluid required with new brake pads. If the fall in fluid level is moderate, due to normal brake pad wear, topping up is not necessary.

Brake fluid reservoir

If the brake fluid should require chang- ing, this must be carried out at a Saab dealer.

The foot brake and parking brake are self- adjusting. It is not possible to detect, through abnormal pedal or parking brake lever travel, whether the brake pads are worn and need replac- ing. It is therefore essential that brake pads be checked regularly, as specified in the service program.

NOTICE

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.

Brake pads should only be changed at a Saab dealer. To ensure optimum brake performance, use only Saab genuine brake pads.

Power steering

WARNING

Power steering fluid on hot engine components 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 directly forwards during this check. Clean round the cap before unscrewing it. Wipe the dipstick. To check the level, screw down the cap completely and then remove it again. The oil level should lie between the MAX and MIN marks when the oil temperature is about 68°F (+20°C). If the oil is colder, the level will be lower, and at a higher tempera- tures the level will be higher, both of which are acceptable. Top up with "CHF 11S power steering fluid".

Battery

WARNING

(cid:127) When working on the battery, highly explosive gas can build up. A spark could ignite this gas that collects around the battery. Therefore, always avoid sparks and open flames in the vicinity of 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 onto 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.

Checking the battery electrolyte level. Level correct if level indicator dark

Check the charge state and electrolyte level of the battery regularly.

NOTICE

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

If frequent short journeys are made, the battery may need extra charging. This can be done with a battery charger or by taking the car for a long run. If the battery is not being charge while the engine is running, the following message will appear on the SID:

Battery not charging. Make a safe stop. Contact Saab dealer.

Check the drive belt (see page 185). If the belt is damaged, the engine may overheat, the battery may not be charged and the A/C compressor may not work.

Car care

183

Turn the two retainers a quarter turn to unlock the battery cover.

Battery bracket

Always connect the positive (red) cable to the battery’s positive (+) terminal, and the negative (black) cable to the negative (-) terminal of the battery. Always disconnect both battery leads when boost charging the battery.

NOTICE

(cid:127) If boost charging never use anything

but a 12-volt charger.

• Do not connect the battery termi-

nals, + and –, incorrectly.

(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.

(cid:127) Exercise special care when removing and fitting the positive (+) cable so as not to damage the battery disconnect switch.

A car with standard equipment specifica- tions 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 fit- ted, such as a mobile phone, the charge may only be sufficient for about 15 days.

Car care

Battery disconnect switch

WARNING

If the battery disconnect switch has tripped, do not reset it until you have visu- ally inspected the car’s electrical system. If there are visible signs of damage, have the car checked at a Saab dealer before resetting the disconnect switch.

A crash could cause a short circuit in the alternator or starter motor. A disconnect switch by the battery’s positive terminal cuts off the battery from the alternator and starter motor when the airbags and seatbelt pre- tensioners are detonated.

NOTICE

Exercise special care when removing and fitting the positive (+) cable so as not to damage the battery disconnect switch.

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 these sometimes leave a wax coating on the windshield. If wiper performance is still unsatisfactory, fit new blades.

Change of wiper blades

Washer fluid reservoir

To fit new blades: 1 Press in the catch (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.

Washers

WARNING

Take care not to spill washer fluid concen- trate onto hot surfaces. Washer fluid concentrate can contain flammable ingre- dients such as alcohol.

The reservoir capacity is 5.5 qts (5.2 litres).

Car care

187

When the washer fluid level drops below 1 quart (1 litre), the headlight washers are deactivated. This is in order to prioritize the windshield. The following message is displayed on the SID:

Washer fluid level low. Refill.

Headlight washers are only available on certain markets. Fill with a mixture of "Saab washer fluid" and water as recommended by the table on the packaging to reduce the risk of freezing and to ensure effective cleaning (see also page 76). To prevent the smell of washer fluid from entering the car, recirculation can be acti- vated temporarily while washing the wind- shield. This function can be programmed; contact a Saab dealer.

Washer jets The washer jets, which are adjustable, can be cleaned with a pin if necessary.

Car care

Changing bulbs

WARNING

Before changing a bulb in the engine bay, switch off the engine to avoid the danger of fingers and hands being injured by moving parts. The radiator fan can cut in even when the engine is switched off.

NOTICE

Switch off the ignition before changing a bulb, to avoid possible short-circuiting.

Autochecking of lights The bulbs that are most important from the point of view of traffic safety are monitored by the car’s electrical system. If one of these bulbs should fail, a message will be displayed on the SID. Example of SID message:

Left low beam failure.

The following bulbs are not checked: parking lights, front fog lights, reversing lights, license plate lighting, side marker lights and side direction indicators.

If a brake light bulb fails If a brake light bulb fails, the adjacent tail light will act as a brake light to ensure traffic safety. Change the broken bulb when possible. All rear light bulbs are of the same type and rated 21 W, with the exception of the license plate lighting which is rated 5 W. Wrong bulb fitted If a dipped or main beam bulb of too high a rating is fitted, a bulb failure message will be shown on the SID (a too high wattage bulb can damage the reflector). If the following message is displayed but the bulb shines, it is most likely that an incorrect bulb has been fitted.

Right high beam failure.

Note: When changing bulbs, fit the same type of bulb (e.g. Long-Life) as that removed. Headlight aiming, page 226.

Car care

Contact a Saab dealer to have a Bi-Xenon headlight changed

Bi-Xenon headlight, main and dipped beam (certain variants only)

WARNING

Bi-Xenon headlights are high tension. All work on Bi-Xenon head- lights, including changing bulbs, must be carried out by dealer personnel.

Xenon headlights produce roughly three times as much light as halogen bulbs and have a significantly longer service life. The lamp units consist of a gas discharge lamp containing xenon. When the lights are switched on a very high voltage activates the xenon gas. The lamps soon reach full intensity. Cars with Bi-Xenon headlights have automatic levelling. The level- ling system comprises two sensors, one on the front suspension and one on the rear suspension, and a control unit by the engine bay fuse box. Headlight alignment is adjusted automatically to the car’s load to prevent dazzling drivers in oncoming traffic. If a fault is detected in the system, the following message will be dis- played on the SID:

Headlight levelling malfunction. Contact Saab dealer.

Fuses

WARNING

To avoid the risk of short-circuiting and/or fire breaking out in the electrical system, the following should be heeded: (cid:127) Always consult an 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 rating than specified (see page 201). The color of the fuse indi- cates its amperage.

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

have the electrical system checked by an 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 Saab dealer.

200

Car care

Fuse panel in end of fascia

A special tool for removing fuses is provided on the hatch on the left-hand end of the fas- cia. Simply push the tool onto the fuse, squeeze and remove the fuse. Some fuses and relays may be fitted but not connected to the car’s electrical system.

MAXI fuses The car also has a number of large fuses known as MAXI fuses. These are designed to protect the car’s electrical system from being damaged. Each MAXI fuse protects a number of electrical circuits and functions and therefore has a higher rating (amper- age) than the standard fuses. No spare MAXI fuses are supplied with the car.

NOTICE

If a MAXI fuse blows, there is a major fault in the electrical system. Have the car checked at a 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 available. 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.

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. Do not take it for granted that a wheel/tire combination will work in the best possible way, just because it can be fitted to the car. To ensure that the speedometer is as accu- rate as possible it should be reprogrammed if wheels of a different dimension are fitted. Contact a Saab dealer.

NOTICE

Always consult your Saab dealer before changing the car’s wheels or tires on your Saab. Wide wheels and tires with side walls that are too low can: (cid:127) be damaged in potholes, etc.

(cid:127) cause springs, shock absorbers and wheel bearings and body mountings to be overloaded

(cid:127) cause the wheels to come into contact

with chassis and body components

(cid:127) affect the function of the Electronic

Stability Program (ESP).

The speed and load limits of the tires must not be exceeded; see page 209.

Wheels larger than 18" must not be fitted on the Saab 9-3. The permissible offset is 1.61 inch (41 mm).

Tire pressure

WARNING

Check the tire pressure at least once a month and before long journeys. Under- inflation can result in: (cid:127) punctures (cid:127) separation of the tire and tread (cid:127) damage to the sidewalls (cid:127) damage to the rims on poor roads (cid:127) poor handling characteristics.

Note: Low tire pressure also causes prema- ture tire wear and increased fuel consump- tion. Adjust the tire pressure to match the current load and speed of the car (see page 245). The stated tire pressures apply to cold tires, i.e. tires that are the same temperature as the outside air temperature. Tire pressure increases as the tires become warm (e.g. during highway driving) by approximately 0.3 bar (4 psi). When the temperature of the tires changes by 50°F (10°C), the tire pres- sure will change 0.1 bar (2 psi). 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. If a valve is leaking, simply unscrew it and fit a new one. Note: Remember to adjust the tire pressure if you change the load in the car or intend to cruise at a speed that is substantially differ- ent from normal.

Car care

207

Automatic tire pressure monitoring (option, certain variants only)

WARNING

The system is intended to aid the driver. The driver is always ultimately responsi- ble for ensuring that the tire pressure is correct.

The pressure monitoring system consists of a sensor in each wheel, a detector in each wheel housing and a receiver. The sensors are located inside the wheels directly adja- cent to the air valves.

NOTICE

Great care must be taken when changing tires so as not to damage the sensors that are integrated in the valves.

208

Car care

The receiver is located in the trunk. Tire pressure information is sent wirelessly to the receiver. The system checks the tire pressure when the car is travelling over 18 mph (30 km/h). The system is "self-learning", which means that the position of the wheels can be changed without requiring adjustments to the monitoring system. The spare wheel does not have a sensor. The sensor batteries have an average life of 10 years. The batteries cannot be changed but require the sensor units to be replaced. The system does not warn if a tire is overin- flated.

Valve with sensor

Valve without sensor

If the tire pressure drops If the tire pressure drops 0.3 bar (4 psi) below the recommended pressure, the SID will issue a warning as to which tire is affected.

Tire pressure low, front left. Check tires.

Adjust the tire pressure as soon as possible.

If the tire pressure continues to drop, the SID will issue a warning alarm when the pressure is 0.6 bar (9 psi) below the recom- mended value.

Flat tire front left. Make a safe stop.

Reduce speed (avoid heavy braking and violent steering wheel movements) and stop the car as soon as it is safe to do so. Change the wheel.

Malfunction

Shifting the wheels

Tire pressure system failure. Contact Saab dealer.

The message shown above will be dis- played on the SID if: (cid:127) a wheel without pressure sensor is fitted

(e.g. spare wheel)

(cid:127) one, two or three pressure sensors are

broken or missing two or more detectors are missing or broken the receiver malfunctions

(cid:127) a fault arises in the system. The message shown above is not displayed if none of the wheels have sensors, such as if winter wheels without sensors are fitted.

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 wheels should therefore be moved to the front. Always move rear left to front left and rear right to front right, 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.

Car care

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

211

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.

Wear indicator

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.

212

Car care

Tire 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 have a code that specifies their date of manufacture. The first two digits denote the week number and the last two digits the year. Accordingly, a date code of 3701 signifies that the tire was manufactured in week 37, 2001.

Date code

Compact spare wheel

WARNING

The spare wheel or punctured wheel must be stowed under the trunk floor, and secured in place with the retaining nut.

Compact spare The compact spare is light and easy to handle when changing the wheel. Its use is only permitted when a standard wheel has sustained a puncture. The maximum life of the wheel is only just over 2,000 miles (3,500 km). Do not exceed 50 mph (80 km/h) with the compact spare fitted. The tire pressure should be 60 psi (420 kPa). Put the punctured wheel in the spare wheel well under the trunk floor. Driving with the compact spare wheel, see page 167. Have the standard wheel repaired and refit- ted as soon as possible.

Car care

213

The spare wheel, the tools and the jack with its crank are carried under a panel in the trunk. Fold the carpeting forward to ease access to the tools and spare wheel. The screwdriver handle has a "button" for removing plastic rivets. This type of rivet must be removed when changing the light bulb in the trunk lid (see page 195).

NOTICE

To avoid damaging an alloy wheel with a flat tire, this can be placed outside up in the spare-wheel well but only while driv- ing to the closest workshop. A general rule is that all heavy loads must be well secured in the luggage compart- ment (see page 118).

Spare wheel (under trunk floor)

Your Saab is equipped with a trip computer and you can use its "Speed warning" func- tion, to monitor driving speed since you must not exceed 50 mph (80 km/h).

(cid:127) The jack should be stored correctly under the carpeting in the trunk. If it lies loose in the car, it could thrown forward and cause personal injury in the event of a crash or if the car rolls over.

(cid:127) Do not use the jack on a car other than

your Saab 9-3.

(cid:127) Grit, salt and rust can clog the inner

threads if the car has been driven for several years exclusively with alloy wheels. If steel wheels are now fitted, the bolt hole threads in the brake hubs should be cleaned before the thinner steel wheels are fitted. It may otherwise not be possible to achieve the correct clamping force, despite tightening the wheel bolts to the correct torque.

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.

(cid:127) Never crawl under a car that is

supported only by a jack.

(cid:127) Special care must be taken if the car is on a slope - use wedge-shaped wheel chocks!

(cid:127) Position chocks, one ahead and one behind, the wheel that is diagonally opposite to the one to be changed.

(cid:127) Switch on the hazard warning lights if

the car is on a road.

(cid:127) Apply the parking brake and leave the car in gear (1st or reverse). Automatic transmission: move the selector lever to the P position.

(cid:127) Ensure that everybody is out of the car

before jacking it up.

(cid:127) Never start the engine while the car is

jacked up.

(cid:127) If possible, make sure the jack is standing on a firm, level surface.

Car care

215

Marking of jacking points

Jacking points

Clean any rust or dirt from the contact sur- faces between the wheel and brake disc.

When the car has to be lifted, the jack must be positioned at one of the four jacking points (front or rear) under the sill members. If a floor jack is used, the lifting plate must be positioned under the normal jacking points. If the car is equipped with a towbar, the jack can also be placed under this.

NOTICE

Apply the jack only to the jacking points indicated on the body.

1 Apply the parking brake and engage 1st

or reverse gear (automatic transmis- sion: select P).

2 Wind the jack up to a suitable height

before placing it under the jacking point. Each jacking point is indicated by an

arrow on the sill (see illustration). Make sure that the jack fully engages the jacking point in the underside of the sill member and that the entire foot of the jack is steady and flat on the ground. The jack must not stand on snow, ice or similar. Wind up the jack until it just begins to lift the car.

3 It is not necessary to remove the wheel

cover. If, none the less, you wish to remove the wheel cover, take hold of the outer edge and pull it straight out. Loosen the wheel bolts half a turn.

4 Wind the jack to raise the wheel clear of the ground. Remove the wheel bolts and lift off the wheel.

5 Clean any rust or dirt from the contact surfaces between the wheel and brake disc. Do not wipe away the grease in the wheel hub.

6 Fit the wheel and screw in the bolts in the sequence shown on the following page (opposite pairs). Tighten the bolts enough for the bolts and wheel to be seated correctly.

7 Lower the car and tighten the wheel

bolts to torque in sequence as shown on the following page. Tightening torque: Light-alloy wheels: 110 Nm. Steel wheels: 110 Nm.

216

Car care

Do not wipe away the grease in the wheel hub.

Tightening sequence, wheel bolts

We advise against using wheels with large ventilation slots in winter, as the brake com- ponents are then more exposed to slush, road salt and grit. If you fit wheels of a different dimension, the speedometer can be reprogrammed to ensure it is as accurate as possible. Contact a Saab dealer. Driving with tire chains, see page 156

NOTICE

(cid:127) Do not overtighten the bolts using a

impact wrench: not only can this damage the wheels but it can also make it impossible to undo the bolts using the wheel wrench in the car’s toolkit.

(cid:127) When refitting a wheel cover, make

sure that the valve protrudes through the marked recess in the wheel cover.

8 Retighten the wheel bolts after twenty or

so miles. Tightening torque: Light-alloy wheels: 110 Nm. Steel wheels: 110 Nm.

Flat spotting All tires get hot, especially on long journeys or when the car is driven hard. After the car has been parked with hot tires and the tires have cooled down, a flat spot can form in the tire, where it is in contact with the ground. The same can occur if the car has not been moved for a long time. Flat spots can cause vibration that can be felt through the steering wheel, similar to that experienced when the wheels need bal- ancing. Flat spots of this type disappear once the tires get hot again, usually after 10–15 miles (20–25 km) of driving at cruising speed.

217

Car care Upholstery and trim To remove fluff and hairs from the seats, door armrests and headlining, use a vacuum cleaner, a moist lint-free cloth, or a clothes brush. Remove spots and dirt using a cloth moistened with lukewarm soapy water. When using a stain remover, always work from the outside towards the centre to avoid leaving a ring. If a soiled ring or spot should remain, it can usually be removed using lukewarm soapy water or water alone. Spots left by liquids, such as soft drinks or thin oil, must be removed at once with an absorbent material, such as kitchen towel- ling. Then clean with a stain remover. White spirit is recommended for removing grease and oil stains. A medium stiff brush may also be used.

Safety belts

WARNING

If the car is involved in a crash, the safety belts, belt pretensioners and other asso- ciated components must be inspected at a Saab dealer. Never make any alterations or repairs to the safetybelts yourself but visit a Saab dealer.

Check the function of the safety belts regu- larly as follows: (cid:127) Hold the diagonal strap and pull it sharply. The safety belt should lock and it should not be possible to withdraw it further.

Check the anchorage points in the floor. They must not have suffered rust damage. If a belt is worn or has any fraying edges, it should be replaced. Safety belts must not come into contact with substances such as polishes, oil or chemi- cals. If the belts get dirty, wash them with warm water and a detergent or have them replaced.

Car care

Cleaning and caring for leather upholstery The principal reason for treating leather upholstery is to maintain its elegant appear- ance and to provide it with a protective film. Discolouration caused by dust and wear mainly affects the lighter shades, although this is not detrimental to the leather, indeed, the patina resulting from use is often consid- ered desirable in leather. But if the leather is allowed to become too grubby, it can start to look shabby. The leather upholstery should be cleaned and reconditioned twice a year in conjunc- tion with spring and autumn inspections. In very warm, dry climates the leather may need more regular reconditioning. Recom- mended conditioner – Saab Leather Care Lotion. Do not use unknown harsh polishing agents, cleaning agents, sprays, coarse soap or hot water.

Textile carpeting Textile carpeting should be vacuum cleaned regularly. Carpeting can also be cleaned using a brush or sponge and carpet shampoo. For safety reasons, vacuum cleaners that are not earthed (grounded) must not be used out of doors. Engine bay The engine bay should be cleaned with an engine degreasant and rinsed with hot water. The headlights must be covered over. Do not use a pressure washer. Do not use petrol as a cleaning agent or sol- vent when carrying out repairs or mainte- nance. Saab recommends the use of envi- ronmentally-friendly degreasants.

Washing The bodywork must be washed frequently. When the car is new, the body should be washed by hand using plain cold water and a clean, soft brush through which the water flows. Automatic carwashes should be avoided when the car is new. After 5–6 months the paintwork will have hardened. To facilitate cleaning, a suitable detergent can be added to the water, which should be lukewarm. Remove any bird droppings without delay, as these can discolour the paintwork and prove difficult to polish out. Lay a wad of wet paper on the patch of dirt and leave it for a minute or so. It will then be easy to wash off the dirt. Use a soft cloth moistened with white spirit to remove splashes of tar or asphalt. Do not use strong cleaners, as these can dry out the paintwork.

NOTICE

Do not use alcohol-based cleaners on the plastic lenses of the front or rear lights, as these can cause a crackling effect on the lenses. The door mirrors should be folded in before the car enters an automatic car wash.

The underside of the car also needs wash- ing regularly, and this should be done extra

thoroughly at the end of winter. Clean the underside of the car by hand if the car is usu- ally washed in an automatic car wash with- out special facilities for underbody cleaning. Never wash or leave the car to dry in the sun, but wipe it dry with a chamois leather immediately after washing to avoid smears and streaks. Clean the inside of window glass using a proprietary window cleaner. This is particu- larly important when the car is new, as upholstery and trim have a tendency to sweat a little at first. Keep the glass well polished, as this helps to prevent misting. Clean the outside of the windows with Saab washer fluid. This is especially important if the car has been washed in an automatic car wash, as sometimes a wax treatment is used that can contaminate the windshield and impair the performance of the wipers.

NOTICE

(cid:127) Try your brakes on leaving a car wash.

Wet brake discs reduce the perfor- mance of the brakes.

(cid:127) Fixed antennae, such as for a mobile

phone, must be removed if the car goes through an automatic car wash.

(cid:127) Cars with Saab Parking Assistance: Do not spray the sensors or closer than 8 in. (20 cm) to the sensors with a pressure washer, as this can damage them.

Waxing and polishing Do not wax a new car during the first three or four months. In fact, there is no need to polish the car before the paintwork has started to go dull through oxidation. Other than in exceptional cases, do not use abra- sive polishes containing a cutting agent on a new car. Always wash the car thoroughly before waxing or polishing.

Car care

219

Touching up the paint Damaged paintwork should be treated as soon as it is discovered: the longer it is left, the greater the risk of corrosion. The anti- corrosion warranty does not cover corrosion resulting from untreated defects. Paintwork damage sustained in a crash is usually extensive and can only be properly restored by professionals. However, you can repair small scratches and stone chip damage yourself. The nec- essary tools and materials, such as primer, touch-up paint and brushes, are available from your Saab dealer. In the case of minor flaws in the paintwork, where the metal has not been exposed and an undamaged layer of paint remains, touch-up paint can usually be applied directly, after any dirt has been scraped away using a pointed knife. If corrosion has already set in, such as the result of stone-chip damage, use a pointed knife to scrape off all surface rust. If possi- ble, the damaged area should be taken
