page 64).
Starting difficulties
If the engine does not start as described,
carry out the following steps:
If you are starting the engine with the
SmartKey: Turn SmartKey in starter
switch to position0 and repeat starting
procedure.
If you are starting the engine with
KEYLESS-GO*: Close any doors that
may be open to allow for better detec-
tion of the SmartKey with
KEYLESS-GO*.
Or:
Start the engine with the SmartKey as
radio signals from another source may
be interfering with the SmartKey with
KEYLESS-GO*.
Warning!G
As long as the SmartKey with KEYLESS-GO
is in your vehicle, the vehicle can be started.
Therefore, never leave children unattended
in the vehicle, as they could otherwise
accidentally start the engine.
When leaving the vehicle, always take the
SmartKey with KEYLESS-GO with you and
lock the vehicle. Do not leave children
unattended in the vehicle, or with access to
an unlocked vehicle.

55 Getting started
Driving
Repeat the starting procedure
(
page 53). Remember that extended
starting attempts can drain the battery.
Get a jump start (page 432).
If the engine does not start after several
starting attempts, there could be a mal-
function in the engine electronics or in the
fuel supply system.
Contact an authorized Mercedes-Benz
Center or call Roadside Assistance.
Parking brake
1Release handle
Release the parking brake by pulling on
release handle1.
The brake warning lamp;(USA
only) or3 (Canada only) in the
instrument cluster goes out.
Warning!G
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children
unattended in the vehicle, or with access to
an unlocked vehicle. Children could release
the parking brake, which could result in an
accident and/or serious personal injury.

56 Getting started
Driving
Driving off
Depress the brake pedal.
Place the gear selector lever in
positionD orR.
Release the brake pedal.
Carefully depress the accelerator
pedal.After a cold start, the transmission en-
gages at a higher revolution. This allows
the catalytic converter to reach its operat-
ing temperature earlier.
Warning!G
It is dangerous to shift the gear selector le-
ver out ofP orN if the engine speed is high-
er than idle speed. If your foot is not firmly
on the brake pedal, the vehicle could accel-
erate quickly forward or in reverse. You
could lose control of the vehicle 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.
Warning!G
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 ABS will not
prevent this type of loss of control.
!In order to avoid damage to the
transmission:

Wait for the gear selection process to com-
plete before setting the vehicle in motion.

Place the gear selector lever in positionP
orR only when the vehicle is stopped.
!If you hear a warning signal and the
message
Release Parking Brake appears in
the multifunction display when driving off, you
have forgotten to release the parking brake.
Release the parking brake (
page 55).
iOnce the vehicle is in motion, the automatic
central locking system engages and the locking
knobs drop down.
You can deactivate the automatic locking using
the control system (
page 166).
You can open a locked door from the inside.
Open door only when conditions are safe to do
so.
!Do not run cold engine at high engine speed.
Running a cold engine at high engine speed may
shorten the service life of the engine.
!Simultaneously depressing the accelerator
pedal and applying the brakes reduces engine
performance and causes premature brake and
drivetrain wear.

a dry windshield. If it is necessary to operate the
windshield wipers in dry weather conditions,
always operate the windshield wipers with
windshield washer fluid (

(
page 289).
Problems while driving
The engine runs erratically and misfires

An ignition cable may be damaged.

The engine electronics may not be
operating properly.

Unburned gasoline may have entered
the catalytic converter and damaged it.
Give very little gas.
Have the problem repaired by an
authorized Mercedes-Benz Center
as soon as possible.The coolant temperature gauge is
above 248°F (120°C)
The coolant is too hot and is no longer
cooling the engine.
Stop the vehicle as soon as possible in
a safe location and turn off the engine.
Allow engine and coolant to cool off.
Check the coolant level and add cool-
ant if necessary (
page 288).

62 Getting started
Parking and locking
You have now completed your first drive.
You have properly stopped and parked
your vehicle. End your drive as follows.
Warning!G
With the engine not running, there is no
power assistance for the brake and steering
systems. In this case, it is important to keep
in mind that a considerably higher degree of
effort is necessary to brake and steer the
vehicle.
Warning!G
Do not park this vehicle in areas where com-
bustible materials such as grass, hay or
leaves can come into contact with the hot
exhaust system, as these materials could be
ignited and cause a vehicle fire.
To reduce the risk of personal injury or
damage to the vehicle drivetrain as a result
of vehicle movement, before turning off the
engine and leaving the vehicle always:

Keep right foot on brake pedal.

Firmly depress parking brake pedal.

Move the gear selector lever to
positionP.

Slowly release brake pedal.

When parked on an incline, turn front
wheels towards the road curb.

Turn the SmartKey or the SmartKey with
KEYLESS-GO* to starter switch
position0 and remove, or press the
KEYLESS-GO* start/stop button.

Take the SmartKey or the SmartKey with
KEYLESS-GO* with you and lock vehicle

Parking and locking
Parking brake
1Parking brake pedalStep firmly on parking brake pedal1.
When the engine is running, the indica-
tor lamp;(USA only) or3
(Canada only) in the instrument cluster
will be illuminated.
Switching off headlamps
Turn the exterior lamp switch to
position M (
page 131).
Warning!G
Engaging the parking brake while the vehicle
is in motion can cause the rear wheels to
lock up. You could lose control of the vehicle
and cause an accident. In addition, the
vehicle’s brake lights do not light up when
the parking brake is engaged.
Warning!G
When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it with you, and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. Children could release the
parking brake and/or move the gear selec-
tor lever from positionP, either of which
could result in an accident and/or serious
personal injury.
Warning!G
Getting out of your vehicle with the gear se-
lector lever not fully engaged in positionP is
dangerous. Also, when parked on an incline,
positionP alone may not prevent your vehi-
cle from moving, possibly hitting people or
objects.
Always set the parking brake in addition to
shifting to positionP (
page 174).
When parked on an incline, also turn front
wheels towards the road curb.
