Drinking and Driving



Warning !
Drinking and driving can be a very dangerous combination. Even a small amount of alcohol or drugs can
affect your reflexes, perceptions and judgement. The possibility of a serious or even fatal accident is
sharply increased when you drink and drive. Please don't drink and drive or allow anyone to drive after
drinking.


Parking Brake
To engage, firmly depress parking brake pedal. When the electronic key is in steering lock position 2, the brake
warning lamp in the instrument cluster should come on brightly. To release the parking brake, pull handle on
instrument panel. The brake warning lamp in the instrument cluster should go out. A warning sounds, if you start
to drive without having released the parking brake. Also see Brake Warning Lamp Test in Index.


Driving Off
Apply the service brakes to test them briefly after driving off. Perform this procedure only when the road is clear
of other traffic. Warm up the engine smoothly. Do not plac e full load on the engine until the operating temperature has
been reached. When starting off on a slippery surface, do not allow one drive wheel to spin for an extended period.

Warning !
Keep driver's foot area clear at all times. Object s stored in this area may impair pedal movement.

Automatic Transmission

The automatic transmission selects individual gears automatically, dependent upon
• Selector lever position
• Program mode selector
• Accelerator position
• Vehicle speed

Important !

When parking the car or before working on the vehicle with the engine running, firmly depress the parking brake
pedal and shift the selector lever into "P".


Driving
The selector lever is automatically locked while in position "P". To move the selector lever out of position "P", the
service brake pedal must be firmly depressed before the shift lock will release. Shift selector lever to the desired
position only when the engine is idling normally and the service brake is applied. Do not release the brake until
ready to drive. The vehicle may otherwise start creeping when the selector lever is in drive or reverse position.

Warning !
It is dangerous to shift the selector lever out of "P" or "N" if the engine speed is higher than idle speed. If
your foot is not firmly on the brake pedal, the car could accelerate quickly forward or in reverse. You
could lose control of the car and hit someone or something. Only shift into gear when the engine is idling
normally and when your right foot is firmly on the brake pedal.

Important !
After selecting any driving position from "N" or "P", wait a moment to allow the gear to fully engage before
accelerating, especially when the engine is cold.


Accelerator Position
Partial throttle = early upshifting = normal acceleration
Full throttle = later upshifting = rapid acceleration
Kickdown (depressing the accelerator beyond full throttle) = downshifting to a lower gear = maximum acceleration.
Once the desired speed is attained, ease up on t he accelerator - the transmission shifts up again.




Selector Lever Positions

The automatic gear shifting process can be adapted to specific operating
conditions using the selector lever.

P - Parking position.
The parking position is to be used when parking t he vehicle. Engage only with the car stopped. The parking
position is not intended to serve as a brake when the vehicle is parked. Rather, the driver should always use
the parking brake in addition to placing the selector lever in park to secure the vehicle.

Note:
The electronic key can be removed from the steering lo ck only with the foot off the brake pedal and the selector
lever in position "P". With the electronic key removed, the selector lever is locked in position "P".


R - Reverse gear. Shift to reverse gear only with the car stopped.
N - Neutral.
No power is transmitted from the engine to the rear axle. When the brakes are released, the vehicle can be
moved freely (pushed or towed). Do not engage "N" while driving except to coast when the vehicle is in danger of
skidding (e.g. on icy roads, see Winter driving Instructions in Index).





ProCarManuals.com

Important !
Coasting the vehicle, or driving for any other reason with selector lever in "N" can result in transmission damage
that is not covered by the Mercedes-Benz Limited Warranty.


D - The transmission automatically upshifts through 5th gear . Position "D" provides optimum driving characteristics
under all normal operating conditions.
4 - Upshift through 4th gear only.
Suitable for performance driving. To shift from position "D" to "4", push selector lever to the left.
3 - Upshift through 3rd gear only.
Suitable for moderately steep hill s. Since the transmission does not shift hi gher than 3rd gear, this gear selection
will allow use of the engine's braking power downhill.
2 - Upshift through 2nd gear only.
For driving in mountainous regions or under extreme operating conditions. This gear selection will allow use of the
engine's braking power when descending steep grades.
1 - In this position, the engine's
braking effect is utilized by shifting into 1 st gea r. Use this position while descending very steep or lengthy
downgrades and only at speeds below 40 mph (60 km/h).


Important !
With selector lever in position "D", "4" or "3", upshifting from 1st to 2nd to 3rd gear is delayed depending on vehicle
speed and engine temperature. This allows the catalytic converter to heat up more quickly to operating temperatures.
During the brief warm-up period this delayed upshift and increased engine noise might be perceived as a malfunction.
However, neither the engine nor transmission are negatively affected by this mode of operation.
The delayed upshift is effective with vehicle speeds below 31 mph (50 km/h) at partial throttle and engine
temperatures below 95°F (35°C). To avoid overrevving the engi ne when the selector lever is moved to a lower driving
range, the transmission will not shift to a lower gear as l ong as the vehicle speed exceeds the speed limit of that gear.
To prevent the engine from laboring at low RPMs, do not allow the engine speed to drop too low on uphill gradients.
Depending on the degree of the incline, shift selector feve r to a lower gear range early enough to maintain engine
RPM within the best torque range.

Warning!

On slippery road surfaces, never downshift in order to obtain braking action. This could result in rear wheel
slip and reduced vehicle control. Your vehicle's AB S will not prevent this type of loss of control.

Maneuvering
To maneuver in tight areas, e.g. when pulling into a parki ng space, control the car speed by gradually releasing the
brakes. Accelerate gently and never abr uptly step on the accelerator. To rock a car out of soft ground (mud or snow),
alternately shift from forward to reverse, while applying slight partial throttle. Rocking a car free in this manner may
cause the ABS malfunction indicator lamp to come on. Turn off and restart the engine to clear the malfunction
indication.

Stopping
For brief stops, e.g. at traffic lights, leave the transmission in gear and hold vehicle with the service brake. For longer
stops with the engine idling, shift into "N" or "P" and hold t he vehicle with the service brake. When stopping the car on
an uphill incline, do not hold it with the accelerator, use the brake. This avoids unnecessary transmission heat build
up.

Warning !

Getting out of your car with the selector lever not fully engaged in position "P" is dangerous. Also, when
parked on an incline, position "P" alone may not pr event your vehicle from moving, possibly hitting people
or objects. Always set the parking brake in addition to sh ifting to position "P". When parked on an incline,
also turn front wheel against curb.

Cruise Control



Cruise Control
Any given speed above approximately 22 mph (35 km/h) can be maintained with the cruise control by operating the
lever.
1. Accelerate and set:
Lift lever briefly to set speed. Hold lever up to accelerate.
2. Decelerate and set:
Depress lever briefly to set sp eed. Hold lever down to decelerate.
Normally the vehicle is accelerated to the desired speed with the accelerator. Speed is set by briefly pushing
the lever to position 1 or 2. The accelerator can be released. The speed can be increased (e.g. for passing)
by using the accelerator. As soon as the accelerator is released, the previously set speed will be resumed
automatically. If a set speed is to be increased or decreased slightly, e.g. to adapt to the traffic flow, hold lever in
position 1 or 2 until the desired speed is reached, or br iefly tip the control lever in the appropriate direction for
increases or decreases in 0.6 mph (1 km/h) increment s. When the lever is released, the newly set speed remains.
3. Canceling
To cancel the cruise control, briefly push lever to position 3.
When you step on the brake or the vehicle speed drops below approx. 22 rnph (35 km/h), for example when driving
upgrade, the cruise control will be canceled. If the cruise control cancels by itself and remains inoperative until the
engine is restarted, have the syst em checked at your authorized Mercedes-Benz dealer as soon as possible.
4. Resume
If the lever is briefly pushed to position 4 when drivi ng at a speed exceeding approx. 22 mph (35 km/h), the vehicle
resumes the speed which was set prior to the cancella tion of the cruise control. The last memorized speed is
canceled when the key in the steering lock is turned to position 1 or 0.



Note:
If the engine does not brake the vehicle sufficiently while dr iving on a downgrade, the speed you set on the cruise
control may be exceeded and you may have to step on the brake pedal to slow down.
As soon as the grade eases, the cruise controlled speed w ill again be maintained as long as the brakes were not
previously applied, or the lever may be used to resume the previously set speed if the brakes were applied.


Caution !
Moving gear selector lever to position "N" switches the cruise control off.

Warning !
Only use the cruise control if the traffic and weather conditions make it advisable to travel at a steady speed.
• The use of cruise control can be dangerous on winding roads or in heavy traffic because conditions do not
allow safe driving at a steady speed.
• The use of cruise control can be dangerous on slippery roads. Rapid changes in tire adhesion can result
in wheel spin and loss of control.
The "Resume" function should only be operated if the driv er is fully aware of the previously set speed and
wishes to resume this particular preset speed.

Exterior Lamp Failure Indicator Lamp
With the electronic key in steering lock position 2, an indicator lamp comes on. It should go out when the engine is
running. If the warning lamp does not go out after starting the engine, or if it comes on while driving, this lamp
indicates a failure in the parking lamp, taillamp, stop lamp, or low beam headlamp. If an exterior lamp fails, the
indicator lamp will come on only when that lamp is switched on. If a brake lamp fails, the lamp failure indicator will
come on when applying the brake and st ay on until the engine is turned off.

Note:
If additional lighting equipment is installed (e.g. auxiliary headl amps etc.) be certain to connect into the fuse before
the failure indicator monitoring unit in order to avoid damaging the system.


Brake Pad Wear Indicator Lamp
With the electronic key in steering lock position 2, the brake pad wear indicator lamp comes on for approximately 30
seconds. It goes out when the engine is running.
If the indicator lamp lights up during braking, this indica tes that the brake pads are worn down. Have the brake
system checked at your authorized Mercedes- Benz dealer as soon as possible.


Brake Warning Lamp
With the electronic key in steering lock position 2, the brake warning lamp will come on. It should go out when the
engine is running. The brake warning lamp will come on:

• when there is insufficient brake fluid in the rese rvoir (engine running and parking brake released), or
• when the parking brake is set (engine running).

Warning !
Driving with the brake warning lamp on can result in an accident. Have your brake system checked
immediately if the brake warning lamp stays on. Don't add brake fluid before checking the brake system.
Overfilling the brake fluid reservoir can result in spilling brake fluid on hot engine parts and the brake fluid
catching fire. You can be seriously burned.

If you find that the minimum mark on the brake fluid reserv oir is reached, have the brake system checked for brake
pad thickness and leaks. To test the brake warning lamp, turn electronic key in steering lock to position 2. The brake
warning lamp comes on, and should go out when the engine is running.

Antilock Brake System (ABS)

Important !
The ABS improves steering control of the vehicle during braking maneuvers. Do not pump the brake pedal, rather use
firm, steady brake pedal pressure. Pu mping the brake pedal defeats the pur pose for ABS and significantly reduces
braking effectiveness.
The ABS prevents the wheels from locking up above a vehicl e speed of approximately 5 mph (8 km/h) independent of
road surface conditions.
At the instant one of the wheels is about to lock up, a slight pulsation can be felt in the brake pedal, indicating that the
ABS is in the regulating mode. Keep firm and steady pressure on the brake pedal while experiencing the pulsation.
On slippery road surfaces, the ABS will re spond even with light brake pedal pressure because of the increased
likelihood of locking wheels. The pulsating brake pedal can be an indication of hazardous road conditions and
functions as a reminder to take extra care while driving.


ABS Control
The ABS malfunction indicator lamp in the instrument cl uster comes on with the electronic key in steering lock
position 2 and should go out when the engine is running.
If the charging voltage falls below 10 volts, the malfunction indicator lamp comes on and the ABS is switched off.
When the voltage is above this value again, the malfunction indicator lamp should go out and the ABS is operational.
With the ABS malfunctioning, the ASR or ESP, if vehicl e so equipped, are also switched off. Both malfunction
indicator lamps come on with the engine running. If the ABS malfunction indicator lamp does not go out or comes on
while driving, it indicates that the ABS has detected a malfunction and has switched off. In this case, the brake
system functions in the usual manner, but without antilock assistance.
Have the system checked at your authorized Mercedes-Benz dealer as soon as possible.

Warning !
ABS cannot prevent the natural laws of physics from acting on the vehicle, nor can it increase the traction
made available by the road conditions. The ABS ca nnot prevent accidents, including those resulting from
excessive speed in turns, following another vehicle too cl osely, or aquaplaning. Only a safe, attentive, and
skillful driver can prevent accidents. The capabilities of an ABS equipped car must never be exploited in a
reckless or dangerous manner which could jeopardize the user's safety or the safety of others.

Note:
To alert following vehicles to slippery road conditions you discover, operate your hazard warning flashers as
appropriate.

Brake Assist System (BAS)

Warning !
BAS cannot prevent the natural laws of physics from acting on the vehicle, nor can it increase braking
efficiency beyond that afforded by the condition of the vehicle brakes and tires or the traction afforded. The
BAS cannot prevent accidents, including those resulting from excessive speed in turns, following another
vehicle too closely, or aquaplaning. Only a safe, at tentive, and skillful driver can prevent accidents. The
capabilities of a BAS equipped car must never be explo ited in a reckless or dangerous manner which could
jeopardize the user's safety or the safety of others.

The Brake Assist System is designed to maximize the vehicle's braking capability during emergency braking
maneuvers by having maximum power boost applied to the br akes more quickly in emergency braking conditions
than might otherwise be afforded solely by the driver's braking style. This can help reduce braking distances over
what ordinary driving and braking style might do. The BAS complements the Antilock Brake System (ABS).
To receive the benefit of the system you must apply continuous full braking power during the stopping sequence. Do
not reduce brake pedal pressure.
Once the brake pedal is released, the BAS is deactivat ed The indicator lamps for the ASR and ESP are combined
with the BAS indicator lamp.
The BAS/ASR or BAS/ESP malfunction indicator lamp in the instrument cluster corne on with the electronic key in
steering lock position 2 and should go out with the engine running.
If the BAS/ASR or BAS/ESP malfunction indicator lamp co mes on permanently while the engine is running, a
malfunction has been detected in either system. As a result, it is possible that now only partial engine output will be
available, and pressing the accelerator pedal will require more effort. If the BAS malfunctions. The brake system
functions in the usual manner, but wi thout BAS. If the charging voltage falls be low 10 volts, the malfunction indicator
lamp comes on and the BAS is switched off. When the volt age is above this value again, the malfunction indicator
lamp should go out and the BAS is operational. With t he ABS malfunctioning, the BAS, ASR or ESP are also
switched off. Both malfunction indicator lamps come on with the engine running. Have the BAS, ASR or ESP checked
at your authorized Mercedes-Benz dealer as soon as possible .

Acceleration Slip Regulation (ASR)
The acceleration slip regulation will engage at all vehicle s peeds, if one or both drive wheels begin to lose traction
and spin in acceleration. While engaged, the yellow warni ng lamp in the speedometer dial flashes. With the
acceleration slip regulation engaged, the brake is applied to the spinning drive wheel until slip is brought under
control. If both drive wheels spin, the brake is applied to both drive wheels and simultaneously, engine torque is
limited, to improve the vehicle's driving stability. As traction on the road surface increases, thus allowing
acceleration without slip, the allowable engine torque also increases again and the brake is no longer applied to
drive wheels.

Important !
If the ASR warning lamp flashes, adapt your spee d and driving to the prevailing road conditions.

Caution !
If the vehicle is towed with the front axle raised (see Towing the vehicle in Index), t he engine must be shut off
(electronic key in steer ing lock position 0 or 1). Othe rwise, the acceleration slip regulation will immediately be
engaged and will apply the rear wheel brakes.

Notes:
The indicator lamp for the ASR is combined with that of the BAS The yellow BAS/ASR malfunction indicator
lamp in the instrument cluster and the yellow ASR warning lamp in the speedometer dial come on with the
electronic key in steering lock position 2. They should go out with the engine running. If the BAS/ASR malfunction
indicator lamp comes on with the engine running, a malfunc tion has been detected in either system. Pressing the
accelerator pedal will require greater effort. Only partial engine output will be available.
If the BAS malfunctions, the brake system functions in the usual manner, but without BAS. Have the BAS or ASR
checked at your authorized Mercedes-Benz dealer as soon as possible. With the ABS malfunctioning, the ASR
is also switched off. Driving the vehicle with varied size tires will cause the wheels to ro tate at different speeds,
therefore the acceleration slip regulation may activate (ye llow ASR warning lamp in speedometer dial comes on).
For this reason, all wheels, including the spare wheel, mu st have the same tire size. When testing the parking
brake on a brake test dynamometer, the engine must be shut off. Otherwise, t he acceleration slip regulation will
immediately be engaged and will apply the rear wheel brakes . In winter operation, the maximum effectiveness of
the acceleration slip regulation is only achieved with Mercedes-Benz recommended M+S rated radialply tires
and/or snow chains.

ASR Control Switch



ASR control switch located in center console To improve
the vehicle's traction when driving with snow chains, or
starting off in deep snow, sand or gravel, press the upper half of the ASR switch. The ASR warning lamp, located
in the speedometer dial, is cont inuously illuminated. With the ASR system switched off, the engine torque
reduction feature is cancelled. Therefore, the enhanced vehicle stability offered by ASR is unavailable. Adapt your
speed and driving to the prevailing road conditions. A por tion of the ASR system remains active, even with the
switch in the OFF position. If one drive wheel loses traction a nd begins to spin, the brake is applied until the wheel
regains sufficient traction. The traction control engages at vehicle speeds up to approximately 24 rnph (40 km/h),
and switches off at 50 mph (80 km/h).
Note:
Avoid spinning of one drive wheel. Doing so may cause seriou s damage to the drive train which is not covered by the
Mercedes-Benz Limited Warranty.
The ASR warning lamp, located in the speedometer dial, star ts to flash at any vehicle speed as soon as the tires
lose traction and the wheels begin to spin. To return to the enhanced vehicle stability offered by ASR: press lower
half of the switch (the ASR warning lamp in the speedometer dial goes out).

Important!
If the ASR warning lamp flashes:
• during take-off, apply as little throttle as possible,
• while driving, ease up on the accelerator.
