46 Getting startedDrivingAfter a cold start the automatic transmis-
sion engages at a higher revolution. This al-
lows the catalytic converter to reach its
operating temperature earlier.More information on driving can be found
in the "Operation" section (
page 249).

Warning!
G
On slippery road surfaces, never downshift
in order to obtain braking action. This could
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of loss of control.Warning!
G
It is dangerous to shift the selector lever out
ofPorN if the engine speed is higher than
idle speed. If your foot is not firmly on the
brake pedal, the vehicle could accelerate
quickly forward or in reverse. You could lose
control of the vehicle and hit someone or
something. Only shift into gear when the en-
gine is idling normally and when your right
foot is firmly on the brake pedal.
iTo signal minor directional changes,
move combination switch to point of
resistance only and release. The turn
signal blinks three times.

48 Getting startedDrivingSingle wipe
Press switch briefly in the direction of
arrow1.
The windshield wipers wipe one time
without washer fluid.
Wiping with windshield washer fluid

Push switch in the direction of arrow1
past the resistance point.
The windshield wiper operates with
washer fluid.
Information on filling up the washer reser-
voir can be found in the "Operation" sec-
tion (page 267).
Problems while driving
The engine runs erratically and misfires

An ignition cable may be damaged.


The engine electronics may not be op-
erating properly.


Unburned gasoline may have entered
the catalytic converter and damaged it.

Give very little gas.

Have the problem repaired by an au-
thorized Mercedes-Benz Center as
soon as possible.
!If leaves, snow, etc. block the wind-
shield wipers, switch off the wipers.

For safety reasons, withdraw key
from starter switch. Remove block-
age.


Turn the windshield wipers on
again.
If windshield wipers fail to function at
all in switch positionI,


Set the combination switch to the
next highest wiper speed.


Have the windshield wipers
checked at the nearest authorized
Mercedes-Benz Center.

151 Controls in detail
Automatic transmission
Automatic transmission
Information for driving with an automatic
transmission is found in the "Getting start-
ed" section (
page 43).
Your transmission adapts its gear shifting
process to your individual driving style by
continually adjusting the shift points up or
down. These shift point adjustments are
performed based on current operating and
driving conditions.
If the operating conditions change, the au-
tomatic transmission reacts by adjusting
its gear shift program.The automatic transmission selects indi-
vidual gears automatically, depending on


the selector lever positionD with gear
ranges4, 3, 2, 1 (
page 153)


the selected shift program (W/S)
(page 155)


the position of the accelerator pedal
(page 156)


the vehicle speed
The current selector lever position and
shift program (W/S) appear in the speed-
ometer display (
page 121).
An additional indication of the current se-
lector lever position can be found on the
cover of the shifting-gate. The indicators
come on when you activate a switch (e.g.
unlocking the vehicle or opening a door)
and go out after approximately 15 min-
utes.When the selector lever is in positionD,
you can influence transmission shifting by


limiting the gear range


changing gears yourself
iDuring the brief warm-up, the transmis-
sion upshifting is delayed. This allows
the catalytic converter to heat up more
quickly to operating temperatures.
Warning!
G
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 vehicle could accelerate
quickly forward or reverse. You could lose
control of the vehicle and hit someone or
something. Only shift into gear when the en-
gine is idling normally and when your right
foot is firmly on the brake pedal.

256 OperationDriving instructionsControl and operation of radio trans-mitter
COMAND*, radio and telephone*Telephones and two-way radios
Radio transmitters, such as a portable tele-
phone or a citizens band unit should only
be used inside the vehicle if they are con-
nected to an antenna that is installed on
the outside of the vehicle.
Refer to the radio transmitter operation in-
structions regarding use of an external an-
tenna.
Catalytic converter
Your Mercedes-Benz is equipped with
monolithic type catalytic converters, an
important element in conjunction with the
oxygen sensors to achieve substantial con-
trol of the pollutants in the exhaust emis-
sions. Keep your vehicle in proper
operating condition by following our rec-
ommended maintenance instructions as
outlined in your Service Booklet.
Warning!
G
Please do not forget that your primary re-
sponsibility is to drive the vehicle. Only op-
erate the COMAND (Cockpit Management
and Data System), radio or telephone
1 if
road and traffic conditions permit.
Bear in mind that at a speed of just 30 mph
(approximately 50 km / h), your vehicle is
covering a distance of approximately
44 feet (approximately 13.5 m) every sec-
ond.
1Observe all legal requirements
Warning!
G
Never operate radio transmitters equipped
with a built-in or attached antenna (i.e. with-
out being connected to an external antenna)
from inside the vehicle while the engine is
running. Doing so could lead to a malfunc-
tion of the vehicle’s electronic system, pos-
sibly resulting in an accident and personal
injury.
!To prevent damage to the catalytic con-
verters, use only premium unleaded
gasoline in this vehicle.
Any noticeable irregularities in engine
operation should be repaired promptly.
Otherwise, excessive unburned fuel
may reach the catalytic converter,
causing it to overheat, which could
start a fire.

263 Operation
Engine compartment
You can check the engine oil level on the
multifunction display.
Turn the key in the starter switch to
position2.
The standard display (
page 121) should
appear in the multifunction display.

Press button k or j, on the
steering wheel until the following mes-
sage is seen in the multifunction dis-
play:Engine oil level - Measuring now!
Measurement correct only if veh.

If necessary, add engine oil.Adding engine oil
1Filler neck

Unscrew the cap from filler neck 1. Be
careful not to overfill with oil.
Be careful not to spill any oil when adding.
Avoid environmental damage caused by oil
entering the ground or water.

Screw the cap back on the filler neck.!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.

346 Practical hintsJump starting
Jump starting
If the battery is discharged, the engine can
be started with jumper cables and the bat-
tery of another vehicle. Observe the follow-
ing:

Jump starting should only be performed
when the engine and catalytic convert-
er are cold.


Do not start the engine if the battery is
frozen. Let the battery thaw out first.


Only jump start from batteries with the
same voltage rating.


Use only jumper cables with sufficient
cross-section, insulated terminal
clamps and polarity reversal protec-
tion.
Warning!
G
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 injured.
Battery fluid contains sulfuric acid. Do not
allow this fluid to come in contact with eyes,
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.
iJumper cables with polarity reversal
protection are available at any autho-
rized Mercedes-Benz Center.
!Jump starting may only be performed
on the main battery installed in the
trunk.
Avoid repeated and lengthy starting at-
tempts.
Do not attempt to start the engine us-
ing a battery quick charge unit.
If the engine does not run after several
unsuccessful starting attempts, have it
checked at the nearest authorized
Mercedes-Benz Center.
Excessive unburned fuel generated by
repeated failed starting attempts may
damage the catalytic converter.
Make sure the jumper cables do not
have loose or missing insulation.
Make sure the cable clamps do not
touch any other metal part while the
other end is still attached to a battery.
