and/or serious personal injury.
iThe last set steering wheel position is stored
when
the ignition is switched off (page 40)
the position is stored in memory
(
page 129)
iIf the current position for the steering wheel
is in the uppermost tilt position, the steering
wheel will no longer be able to move upward
when the easy-entry/exit feature is activated.
The adjustment procedure is briefly interrupted
when the engine is started.
Warning!G

procedure before setting the vehicle in mo-
tion. All steering wheel adjustment must be
completed before setting the vehicle in mo-
tion. Driving off with the steering wheel still
adjusting could cause the driver to lose con-
trol of the vehicle.

with KEYLESS-GO, see “Turning off with
KEYLESS-GO*” (
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

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.
