Driving Instructions
Warning !
If you feel a sudden significant vibration or ride disturbance, or you suspect that possible damage
to your vehicle has occurred, you should turn on the hazard flashers, carefully slow down, and drive with
caution to an area which is a safe distance from the roadway.
Inspect the tires and under the vehicle for possible da mage. If the vehicle or tires appear unsafe, have
it towed to the nearest Mercedes-Benz or tire dealer for repairs.
Power Assistance
Warning !
When the engine is not running, the brake and steering systems are without power assistance.
Under these circumstances, a much greater effo rt is necessary to stop or steer the vehicle.
Brakes
Warning !
After driving in heavy rain for some time without applying the brakes or through water deep enough to
wet brake components, 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.
Resting your foot on the brake pedal will cause excessive and premature wear of the brake pads.
It can also result in the brakes overheating th ereby significantly reducing their effectiveness.
It may not be possible to stop the car in sufficient time to avoid an accident.
The condition of the parking brake system is checked each time the vehicle is in the shop for the required service .
If the parking brake is released and the brake warning lamp in the instrument cluster stays on, the brake fluid level in
the reservoir is too low. Brake pad wear or a leak in the system may be the reason for low brake fluid in the reservoir.
Have the brake system inspected at an aut horized Mercedes-Benz dealer immediately.
All checks and maintenance work on the brake system s hould be carried out by an authorized Mercedes-Benz dealer.
Install only brake pads and brake fluid recommended by Mercedes-Benz.
Warning !
If other than recommended brake pads are installed, or other than recommended brake fluid is used, the
braking properties of the vehicle can be degraded to an extent that safe braking is substantially impaired.
This could result in an accident.
Caution !
When driving down long and steep grades, relieve the load on the brakes by shifting into a lower gear. This helps prevent
overheating of the brakes and reduces brak e pad wear. After hard braking, it is advisable to drive on for some time, rather
than
immediately parking, so the air stream will cool down the brakes faster.
Exterior Lamp Switch
Off
Parking lamps (also side marker lamps, taillamps, license plate lamps, instrument panel lamps)
Canada only: When the engine is running, the low beam is additionally switched on.
Parking lamps plus low beam or high beam headlamps (combination switch pushed forward).
Standing lamps, right (turn left one stop).
Standing lamps, left (turn left two stops).
Front fog lamps (pull out one stop) with parking lamps and/or low beam headlamps on.
Rear fog lamp (pull out to 2nd detent) in addition to fog lamps. Yellow indicator lamp in lamp switch
comes on.
Standing Lamps
When the vehicle is parked on the street the standing lamps (right or left side parking lamps) can be turned on,
making the vehicle more visible to passing vehicles The standing lamps cannot be operated with the electronic key in
steering lock position 2.
Note:
With the electronic key removed and a front door open, a warning sounds if the vehicle's exterior lamps (except
standing lamps) are not switched off. Fog lamps will operate with the parking lamps and the low or high
beam headlamps Fog lamps should only be used in conjunction with low beam headlamps
Consult your State or Province Motor Vehicle Regulations regarding allowable lamp operation. Fog lamps are
automatically switched off when the exterior lamp switch is turned to position .
Daytime Running Lamps
Canada only
When the engine is running and the selector lever is in a driving position, the low beam (includes parking lamps,
side marker lamps, taillamps and license plate lamps) are automatically switched on.
When shifting from a driving position to position "N" or "P", the low beam switches off (2 seconds delay).
For nighttime driving the exterior lamp switch should be turned to position to permit activation of the high beam
headlamps.
Automatic Transmission
The automatic transmission selects individual gears automatically, dependent upon
• Selector lever position
• Program mode selector
• Accelerator position
• Vehicle speed
The gear shifting is process is continuously adapted, dependent on the driving style, the driving situation and the road
characteristics.
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 leverto 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 the 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 the 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 lock 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).
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 1st gear.
Use this position while descending very steep or l engthy 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, if the engine's speed limit would be exceeded. In this case there
will be no downshift, even when the vehicle speed reaches t he engine's speed limit of that gear, e.g. by applying the
service brakes. Continue driving in the usual manner. The transmission will then shift down automatically.
To prevent the engine from laboring at low RPM when driv ing uphill gradients or with your vehicle heavily loaded, the
automatic transmission will downshift when necessary 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 drive wheel
slip and reduced vehicle control. Your vehicle's AB S will not prevent this type of loss of control.
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 ABS 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 vehicle speed by gradually releasing
the
brakes. Accelerate gently and never abruptly step on the ac celerator. To rock a vehicle out of soft ground (mud or
snow),
alternately shift from forward to revers e, while applying slight partial throttle. Rocking a vehicle 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 the vehicle with the service brake. When stopping the
vehicle
on an uphill gradient, do not hold it with the accelerator, use the brake. This avoids unnecessary transmission heat
build up.
Warning !
Getting out of your vehicle with the selector lever not fully engaged in position "P" is dangerous. Also,
when parked on an incline, position "P" alone may not prevent your vehicle from moving, possibly hitting
people or objects. Always set the parking brake in a ddition to shifting to position "P". When parked on
an incline, also turn front wheel against curb.
Program Mode Selector Switch
The transmission is provided with a selector switch for Standard "S" and Winter/Wet (snow and ice) "W" program
modes.
Important !
Always be certain of the program mode selected since the vehicle driving characteristics change with the selection of
the program mode.
S - Standard mode Press switch on symbol "S". Use this mode for all regular driving. The vehicle starts out in 1st
gear.
Accelerator Operation:
Fast on = depressing the accelerator pedal quickly (not into kickdown position) while driving continuously, rather
than depressing the accelerator pedal in the usual manner, will cause the automatic transmission to shift down
into a lower gear.
This gear shifting process is dependent on the current vehicle speed.
Fast off = there will be no upshift when releasing the accelerator pedal quickly, e.g. using the engine's braking
power during performance driving
W - Winter/Wet (snow and ice) mode Press switch on symbol "W".
The vehicle starts out in 2nd gear, except with selector lever in 1st gear, or with accelerator pedal in kick-down
position. The "W" mode helps to improve traction and driving stability of the vehicle.
The gear shifting process occurs at lower vehicle and engine speeds than in the "S,' program mode.
Important
Dependent on the program mode selector switch position "S" or "W" and the gear selector lever in position "13", the
ratio of power transmission changes.
Emergency Operation (Limp Home Mode)
If vehicle acceleration worsens, or the transmission no longer shifts, the transmission is most likely operating in Limp
Home Mode which engages when there is a malfunction at the transmission. This condition may be accompanied by
the "CHECK ENGINE" malfunction indicator lamp in the instrument cluster coming on.
In this mode only the 2nd gear or reverse gear can be activated.
To engage 2nd gear or reverse:
1. Stop the vehicle.
2. Move selector lever to position "P".
3. Turn off the engine.
4. Wait 10 seconds.
5. Restart the engine.
6. Move selector lever to position "D" (for 2nd gear), or move selector lever
to position "R" (for reverse gear).
Have the transmission checked at your authorized Mercedes-Benz dealer as soon as possible.
Cruise Control
Cruise Control
Any given speed above approximately 25 mph (40 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 speed. 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. After 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 briefly tip the lever in the appropriate direction for
increases or decreases in 0.6 mph (1 km/h) increments. When the lever is released, the newly set speed remains.
3. Cancelling
To cancel the cruise control, briefly push lever to position 3.
When you step on the brake pedal or the vehicle speed drops below approx. 25 mph (40 km/h), for example when
driving upgrade, the cruise control will be cancelled. If the cruise control cancels by itself and remains inoperative
until the engine is restarted, have the system checked at your authorized Mercedes-Benz dealer as soon as
possible.
4. Resume
If the lever is briefly pushed to position 4 when driving at a speed exceeding approx. 25 mph (40 km/h), the vehicle
resumes the speed which was set prior to the cancellation of the cruise control. The last memorized speed is
cancelled when the electronic key in the steering lock is turned to position 1 or 0.
Note:
If the engine does not brake the vehicle sufficiently while driving on a downgrade, the speed you set on the cruise
control may be exceeded. In this case the automatic transmission shifts down (max. to 3rd gear) to maintain the set
cruise control speed by using the engine's braking power. As soon as the grade eases, the automatic transmission
shifts up again dependent on the selector lever position. Nevertheless, in some cases you may have to step on the
brake pedal to slow down. In this case the cruise control is switched off. Use the lever to resume the previously set
speed.
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 driver is fully aware of the previously set speed and
wishes to resume this particular preset speed.
Odometer Display Field
(Models C 280 and C 43 AMG)
Turn electronic key in steering lock to position 2 and wait until the symbols and appears in the
odometer display field. Within 1 second press button 0 twice.
The following messages are available:
"OK"
"-1.0 Q" (Canada: -1.0 L)
"-1.5 Q" (Canada: -1.5L)
"-2.0 Q" (Canada: -2.0 L)
If the message "-2.0 Q" (Canada: -2.0 L) blinks and a signal sounds, add oil to upper (max) mark of the dipstick.
"HI"
The message "Hi" blinks and a signal sounds.
Do not overfill the engine.
Excessive oil must be drained or siphoned. It could cause damage to engine and catalytic converter not covered
by the Mercedes-Benz Limited Warranty.
The symbol flashes in the odometer field if a proper oil level check cannot be performed. The oil level check
can be repeated after a short while. Perform the oil level check with the dipstick, if it cannot be completed via the
odometer display field. In this case we recommend that you have the system checked at a Mercedes-Benz dealer.
Notes:
If the symbols and are continuously illuminated after pressing button 0 twice and there is no change in the
odometer display field or the low engine oil level warning lamp comes on, a malfunction has occurred to the system .
Perform the engine oil level check with the dipstick. If no oil leaks are noted continue to drive to the nearest
Mercedes-Benz dealer to have the system checked.
Automatic Transmission Fluid Level
The transmission has a permanent fill of automatic transmission fluid. Regular automatic transmission fluid
level checks and changes are not required. For this reason the dipstick is omitted. If you notice fluid leaks or
gear shifting malfunctions, have your authorized Mercedes-Benz dealer check the transmission fluid level.
Jump Starting
Warning !
Failure to follow these directions will cause damage to the electronic components, and can
lead to a battery explosion and severe injury or death. Never lean over batteries while
connecting or jump starting, you might get injure d. Battery fluid contains sulfuric acid. Do
not allow this fluid to come in contact with ey es, skin or clothing. In case it does, immediately
flush affected area with water, and seek medical help if necessary. A battery will also produce
hydrogen gas, which is flammable and very explosive. Keep flames or sparks away from
battery, avoid improper connection of jumper cables, smoking etc.. Read all instructions
before proceeding.
If the battery is discharged, the engine should be start ed with jumper cables and the (12 V) battery of
another vehicle.
The battery is located in the trunk under the trunk floor.
Proceed as follows:
1 . Position the vehicle with the charged battery so that the jumper cables will reach, but never
let the vehicles touch. Make sure the jump er cables do not have loose or missing insulation.
2. On both vehicles:
• Turn off engine and all lights and accessories, except hazard warning flashers or work lights.
• Apply parking brake and shift selector lever to position "P".
Important !
3. Clamp one end of the first jumper cable to the positive (+) terminal of the discharged
battery and the other end to the positive (+ ) terminal of the charged battery. Make sure
the cable clamps do not touch any other metal parts.
4. Clamp one end of the second jumper cable to the grounded negative (-) terminal of the
charged battery and the final connection to the negative (-) terminal of the discharged battery.
Important !
5. Start engine of the vehicle with the charged battery and run at high idle. Make sure the
cables are not on or near pulleys, fans, or other parts that will move when the engine is
started. Allow the discharged battery to charge for a few minutes. Start engine of the
disabled vehicle in the usual manner.
6. After the engine has started, remove jumper cables exactly reversing the above
installation sequence, starting with the last connection made first. When removing each
clamp, make sure that it does not touch any other metal while the other end is still attached.
Important !
A discharged battery can freeze at approx. +14°F (-10°C ). In that case, it must be thawed out before
jumper cables are used. A frozen battery can explode and cause personal injury.
Jumper cable specifications:
• Minimum cable cross-section of 25 mm
2 or approx. 2 AWG
• Maximum length of 11.5 ft. (3.5 m).
Note:
If engine does not run after several unsuccessful starting attempts, have it checked at the nearest
authorized Mercedes-Benz dealer. Excessive unbur ned fuel may damage the catalytic converter.
