General notes on the central locking system
If the electronic key is inserted in the steering lock, the
vehicle cannot be locked or unlocked with the remote
control.
If the vehicle cannot be locked or unlocked:
•Aim transmitter eye at a receiver of either front door
handle. Check the batteries of the electronic main
key, see page 298, or synchronize the remote
control, see page 300.
•Use the mechanical key to unlock the vehicle. To
start engine, insert the electronic key in the steering
lock. There could be a slight delay until the
electronic key can be turned in the steering lock.Important!
When unlocking the driver’s door with the mechanical
key, the exterior lamps will flash and the alarm will
sound.
To cancel the alarm, insert the electronic key in the
steering lock or press buttonŒ or‹ on the
electronic main key.

To check the engine oil level, park vehicle on level
ground, with engine at normal operational temperature.
Check oil level approximately 5 minutes after stopping
the engine, allowing for the oil to return to the oil pan.Turn the electronic key in steering lock to position 2.
To call up the trip odometer and main odometer, press
button è or ÿ on the multifunction steering
wheel until the display appears. See page 96.
Press button j or k on the multifunction
steering wheel repeatedly until the “MEASUREMENT
CORRECT – ONLY IF VEH. LEVEL” engine oil level
indicator appears. This indicator is only a reminder.
Measurement can be cancelled by pressing button j
or k if the vehicle is not parked on level ground. An
incorrect reading will be recorded if you do not cancel
the measurement. Move the vehicle to level ground and
measure again.
The electronic key in steering lock is not in position 2 if
the “ENGINE OIL LEVEL – SWITCH ON IGNITION”
message appears.
The “ENGINE OIL LEVEL – MEASURING NOW”
message is displayed after approximately 3 seconds.

One of the following messages will subsequently appear
on the indicator:
“ENGINE OIL LEVEL – O.K.”
No oil needs to be added.
“ENGINE OIL LEVEL – ADD 1.0 QUART”
(Canada: 1.0 L)
“ENGINE OIL LEVEL – ADD 1.5 QUART”
(Canada: 1.5 L)
“ENGINE OIL LEVEL – ADD 2.0 QUART”
(Canada: 2.0 L)
See page 268 for instructions on adding engine oil.
“ENGINE OIL LEVEL – REDUCE OIL LEVEL”
Do not overfill the engine.
Excessive oil must be siphoned or drained off. It could
cause damage to the engine and catalytic converter not
covered by the Mercedes-Benz Limited Warranty.
The message “PERF. SERV. ON TIME” (perform service
[engine oil level check] on time) will be displayed if a
proper oil level check cannot be performed. The engine
oil level check can be repeated after a short time.Perform the engine oil level check with the dipstick, if it
cannot be completed via the multifunction display.
See page 268.
In this case we recommend that you have the system
checked at a Mercedes-Benz Center.
Note:
See malfunction and warning messages on page 247
and page 258 if an engine oil level indicator appears on
the multifunction display when the engine is running.
The engine oil level cannot be checked while the engine
is running. The “ENGINE OIL LEVEL – NOT WHEN
ENGINE ON” message will appear.
Engine oil consumption
Engine oil consumption checks should only be made
after the break-in period. During the break-in period,
higher oil consumption may be noticed and is normal.
Frequent driving at high engine speeds results in
increased consumption.

Starting and turning off the engine
Before Starting
Ensure that parking brake is engaged and that selector
lever is in position “P” or “N”. Turn electronic key in
steering lock to position 2.
Starting
Do not depress accelerator.
Briefly turn electronic key in steering lock clockwise to
the stop and release. The starter will engage until the
engine is running.
If engine will not run, and the starting procedure stops,
turn electronic key completely to the left and repeat
starting the engine.
After several unsuccessful attempts, have the system
checked at the nearest authorized Mercedes-Benz
Center.Important!
Due to the installed starter non-repeat feature, the
electronic key must be turned completely to the left
before attempting to start the engine again.
In areas where temperatures frequently drop below
-4°F(–20°C) we recommend that an engine block heater
be installed. Your authorized Mercedes-Benz Center will
advise you on this subject, see page 218.
Turning off
Turn the electronic key in the steering lock to position 0
to stop the engine.
The electronic key can only be removed with the
selector lever in position “P”.

209 Automatic transmission
Te ch n ica l
data Instruments

cluster displayPractical hints Car care Index WWinter / 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.
Caution!
Never change the program mode when the selector lever
is out of position “P”. It could result in a change of
driving characteristics for which you may not be
prepared.
Important!
Always be certain of the program mode selected since
the vehicle driving characteristics change with the
selection of the program mode.
Dependent on the program mode selector switch
position “S” or “W” and the gear selector lever in
position “R”, 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 of 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. Sto p t h e v e h i c l e .
2. Move selector lever to position “P”.
3. Turn off the engine.
4. Wait approximately 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 Center as soon as possible.

Power assistance
BrakesThe condition of the parking brake system is checked
each time the vehicle is in the shop for the required
maintenance 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 f luid in the reservoir.
Have the brake system inspected at an authorized
Mercedes-Benz Center immediately.
All checks and service work on the brake system should
be carried out by an authorized Mercedes-Benz Center.
Install only brake pads and brake fluid recommended by
Mercedes-Benz.
Wa r n i n g !
When the engine is not running, the brake and
steering systems are without power assistance.
Under these circumstances, a much greater effort is
necessary to stop or steer the vehicle.Wa r n i n g !
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 to obtain expected
braking effect. 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 thereby
significantly reducing their effectiveness. It may
not be possible to stop the vehicle in sufficient time
to avoid an accident.
Wa r n i n g !
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.
