Drive Sensibly - Save Fuel

Fuel consumption, to a great extent, depends on driving habits and operat ing conditions.

To save fuel you should:

• keep tires at the recommended inflation pressures

• remove unnecessary loads

• remove ski racks or roof-mounted luggage racks when not in use

• allow engine to warm up under low load use

• avoid frequent acceleration and deceleration

• have all maintenance work per

formed at regular intervals by an authorized MERCEDES-BENZ dealer.

Fuel consumption is also increased by driving in cold weather, in stop- and-go traffic, on short trips and in hilly country.

The First 1500 km (1000 Miles)

The more cautiously you treat your vehicle during the break-in period, the

more satisfied you will be with its per formance later on. Therefore, drive your vehicle during the first 1500 km

(1000 miles) at moderate vehicle and engine speeds.

During this period, avoid heavy loads

(full throttle driving) and high RPM

(no more than 2 /3 of maximum permis sible speed in each gear).

Avoid accelerating by kickdown. It is not recommended to brake the vehi cle by manually shifting to a lower gear. We recommend to select posi tions “ 3” or “ 2” only at moderate speeds (for hill driving).

After 1500 km (1000 miles) speeds may gradually be increased to the permissible maximum.

In either case we recommend that you have the malfunction checked as soon as possible.

See page 67

Catalytic Converter

Your MERCEDES-BENZ is equipped with monolithic catalytic converters, an important element in conjunction with the 0 2-sensor to achieve sub stantial control of the pollutants in the exhaust emissions. Keep your vehicle in proper operating condition by fol lowing our recommended mainte

nance instructions as outlined in your

maintenance booklet.

Caution!

To prevent damage to the catalytic

converters, use only premium unleaded gasoline in this vehicle.

Should any noticeable irregularities in the engine operation occur, exces sive unburned fuel may reach the

converter causing it to overheat.

Warning! As with any vehicle, do not idle,

park or operate this vehicle in

areas where combustible materi als such as grass, hay or leaves can come into contact with the

hot exhaust system, as these materials could be ignited.

Starting and Turning off the Engine

Engage parking brake and move the gear selector lever in either “ P” or “ N” position before starting the engine.

Turn key to steering lock position 2. The charge indicator lamp should come on.

Cold Engine

Turn key in steering lock clockwise to the stop. Do not depress accelerator. Release key only when the engine is firing regularly.

Hot Engine

Turn key in steering lock clockwise to the stop. Do not depress accelerator. If the engine has not fired after approx. 4 seconds, depress accelera tor and continue cranking until the engine is firing regularly. Release key and back off accelerator.

At very high coolant temperatures the engine starting time can be shortened if the accelerator is depressed slowly at the beginning of the starting pro cess.

Turning off

Turn the key to steering lock posi tion 0. Remove the key only when the vehicle has stopped.

If the coolant temperature is very high (e.g. after hard driving on mountain roads), do not shut off the engine immediately, allow it to run for 1 —2 minutes at increased idle speed.

Important!

Due to the installed starter non repeat unit, the key must be returned to steering lock position 0 before a new starting attempt is made.

Observe the oil pressure gauge immediately after starting the engine. In a very cold engine the oil pressure will only rise slowly, some time after the engine has started. Do not speed up the engine before pressure is registered on the pressure gauge.

The charge indicator lamp should go out as soon as the engine has started.

In areas where temperatures fre quently drop below — 25 ° C (— 13 ° F), we recommend that a block heater be installed. Your authorized MERCEDES-BENZ dealer will advise you on this subject.

Driving Instructions

Power assistance

When the engine is not running, the brake and steering systems are with out power assistance. Under these circumstances, a much greater effort is necessary to stop or steer the vehicle.

Brakes Caution!

When driving down long and steep grades, relieve the brakes by shifting into “ 3” or “ 2” . This helps prevent overheating of the brakes and reduces brake pad wear. Do not exceed engine speed limits (see page 62). After hard braking it is advisable to drive on for some time so the air stream will cool down the brakes

faster.

The condition of the parking brake system is checked each time the car is in the shop for maintenance.

Between maintenance checks it is a good practice to apply the parking brake once or twice while driving at approximately 50 km/h (30 mph) on a dry straight road. Apply brake lightly until a slight drag on the wheels is felt. Keep applying brake for about

10 seconds while pulling the release handle out before releasing the park ing brake completely. This practice will keep the parking brake at maxi mum efficiency.

Warning! The stop lamps will not come on

when applying the parking brake only. Perform the procedure in the previous paragraph only when the road is clear of other traffic.

Caution!

Resting your foot on the brake pedal will cause excessive and premature wear of the brake pads.

All checks and maintenance work on the brake system should be carried out by an authorized MERCEDES-

BENZ dealer. If the parking brake is released and

the brake warning lamp in the instru

ment cluster stays on, the brake fluid

level in the reservoir is too low.

Brake pad wear or a leak in the sys tem may be the reason for low brake fluid in the reservoir.

Have the brake system inspected at an authorized MERCEDES-BENZ dealer without delay.

Install only brake pads and brake fluid

recommended by MERCEDES-BENZ.

If other than recommended brake

pads are installed, the braking pro

perties of the vehicle can be affected to an extent that the safety is sub

stantially impaired.

Warning! After driving in heavy rain for

some time without applying the brakes or through water deep enough to wet brake compo nents, the first braking action may be somewhat reduced and increased pedal pressure may be necessary. Be sure to maintain a safe distance from vehicles in front.

i s 1801

Tires

Tread wear indicators (TWI) are

required by law. These indicators are

located in six places on the tread cir cumference and become visible at a depth of approx. 2 mm (V 16 in), at which point the tire is considered worn and should be replaced.

The tread wear indicator appears as a solid band across the tread.

Warning!

Do not allow your tires to wear

down too far. With less than 3 mm

(Vs in) of tread, the adhesion pro

perties on a wet road are sharply reduced.

Depending upon the weather and/or road surface (conditions), the traction varies widely.

Specified tire pressures must be

maintained. This applies particularly if

the tires are subjected to high loads

(e.g. high speeds, heavy loads, high

ambient temperatures).

Aquaplaning

Depending on the depth of the water layer on the road, aquaplaning may occur, even at low speeds and with new tires. Avoid track grooves in the road and apply brakes cautiously in the rain.

Tire traction

The safe speed on a wet, snow cov ered or icy road is always lower than on a dry road.

You should pay particular attention to the condition of the road as soon as the prevailing temperatures fall close to the freezing point.

We recommend M + S radial-ply tires for the winter season for all four wheels to insure normal balanced handling characteristics. On packed snow, they can reduce your stopping distance as compared with summer tires. Stopping distance, however, is still considerably greater than when the road is wet or dry.

Warning! If ice has formed on the road, tire

traction will be substantially reduced. Under such weather conditions, drive, steer and brake with extreme caution.

Drivina Instruction";

Parking

Warning! To reduce the risk of personal

injury as a result of vehicle move ment, before turning off the engine and leaving the vehicle always:

1. Keep foot on brake pedal.

2. Firmly depress parking

brake pedal.

3. Move the selector lever

to position “P”.

4. Slowly release brake pedal.

5. Turn front wheels towards the

road curb.

6. Turn the key to steering lock

position 0 and remove.

Winter Driving Instructions

The most important rule for slippery or icy roads is to drive sensibly and to avoid abrupt acceleration, braking and steering action. Do not use the cruise control system under such conditions.

When the vehicle is in danger of skid ding, move selector lever to position “ N” . Try to keep the vehicle under control by corrective steering action.

Road salts and chemicals can adversely affect braking efficiency. Increased pedal force may become necessary to produce the normal brake effect. We therefore recom mend depressing the brake pedal repeatedly when traveling on salt- strewn roads at length. This can bring road salt impaired braking efficiency back to normal. A prerequisite is, however, that this is possible without endangering other drivers on the road.

If the vehicle is parked after being driven on salt treated roads, the brak ing efficiency should be tested as soon as possible after driving is resumed while observing the safety rules in the previous paragraph.

Note: It is advisable to set the parking brake

whenever leaving the vehicle. In addi tion, move selector lever to position “ P” .

Also, when parking on hills, always apply the parking brake.

Heating, cooling, and air distribution within the vehicle’s interior will be automatically controlled. This is accomplished with the temperature selector (1), the pushbuttons (2) and the fan control buttons (3).

The adjustable air outlets (7) and (8) can be variably opened and closed, or moved to direct the flow of air as desired. The outlets (7) are opened and closed with slide lever (6), and outlets (8) with slide levers (5).

Move slide levers (5) and (6) towards the left to open, towards the right to close.

The air flow from the outlets (9) may be increased by rotating the control (10) up, and reduced by rotating down.

With the exterior lamps turned on

(except standing lamps), the symbols on all buttons light up. Each button shines brighter when depressed.

Notes: The automatic climate control oper

ates properly only if all windows and the sliding roof are kept closed. Air outlets (7), (8) and (9) must not all be closed at the same time.

The air conditioner removes consi derable moisture from the air during operation. It is normal, for water to

drip on the ground through openings

in the underbody.

The adjustable air outlet in the rear passenger compartment console pro vides a variable flow of fresh outside air or cooled air. The air flow is increased by sliding the lever to the left and decreased by sliding the lever to the right.

Temperature Selection ( °C)

The desired interior temperature

can be selected by rotating the

temperature selector. The selected temperature is reached as quickly as possible and maintained. A basic setting of 22 ° C (72 ° F) is recommended.

If desired, the temperature selector can be rotated to the end positions “ MIN” and “ MAX” . This overrides the automatic mode.

“ MIN” (detent) = peak cooling. “ MAX” (detent) = maximum heating. If button 0 is depressed with the

temperature selector in the “ MIN” or “ MAX” end positions, the fan will run at near maximum speed.

Air Recirculation

Press symbol side of switch =

the air recirculation mode is

engaged. The indicator lamp in

the switch lights up. This mode can be selected to prevent

annoying odors or dust from entering the car’s interior.

At high outside temperatures, the system automatically engages the recirculated air mode and thereby increases the cooling capacity per formance.

The recirculated air mode will be auto matically switched off after approxi mately 30 minutes of operation at out side temperatures above approxi mately 7 °C (45 °F) and after approximately 5 minutes at outside temperatures below approximately 7 °C (45 °F).

At outside temperatures above 20 °C (68 °F), the system can be contin uously operated in the recirculated air mode by pressing button 0 or 0 and rotating the temperature selector to end position “ MIN” .

If the windows should fog up from the inside, switch from recirculated air back to fresh air by pressing the lower half of the air recirculation switch (the indicator lamp in the switch goes out).

Note: It is not possible to switch to recircu

lated air if button (0 or is

depressed.
