54 Getting startedDrivingAfter a cold start, the automatic transmis-
sion engages at a higher revolution. This
allows the catalytic converter to reach its
operating temperature earlier.
For more information on driving, see “Driv-
ing instructions” (
page 271).
i
Once the vehicle is in motion, the automatic
central locking system engages and the locking
knobs drop down.
The automatic door lock feature can be deacti-
vated (page 165).
You can open a locked door from the inside.
Open door only when conditions are safe to do
so.
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 gear selector
lever out ofP orN 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 engine is idling normally and when
your right foot is firmly on the brake pedal.
!
Simultaneously depressing the accelerator
pedal and applying the brakes reduces engine
performance and causes premature brake and
drivetrain wear.
!
Do not run cold engine at high engine
speeds. Running a cold engine at high engine
speeds may shorten the service life of the en-
gine.
CLS 63 AMG:
At engine temperatures below 68°F (20°C), the
engine’s maximum speed is restricted in order to
protect it from damage. Avoid driving your vehi-
cle at full speed when the engine is cold to pre-
vent premature engine wear and/or diminished
comfort.

slightly when it is locked. You should there-
fore make sure that no one is standing near
the wheel arches or lying underneath the ve-
hicle when it is being locked. Otherwise,
personal injury could result.
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.

65 Safety and Security
Occupant safety
Warning!
G
Modifications to or work improperly con-
ducted on restraint systems (such as seat
belts and anchors, Emergency Tensioning
Devices, seat belt force limiters or air bags)
or their wiring, as well as tampering with in-
terconnected electronic systems, can lead
to the restraint systems no longer function-
ing as intended.
Air bags or Emergency Tensioning Devices,
for example, could deploy inadvertently or
fail to deploy in accidents although the de-
celeration threshold for air bag deployment
is exceeded. Therefore, never modify the re-
straint systems. Do not tamper with elec-
tronic components or their software.
Warning!
G
In the event that the 1 indicator lamp
comes on during driving or does not come
on at all, the SRS self-check has detected a
malfunction. For your safety, we strongly
recommend that you visit an authorized
Mercedes-Benz Center immediately to have
the system checked; otherwise the SRS may
not be activated when needed in an acci-
dent, which could result in serious or fatal
injury, or it might deploy unexpectedly and
unnecessarily which could also result in
injury.
In addition, improper repair work on the SRS
creates a risk of rendering the SRS inopera-
tive or causing unintended air bag deploy-
ment. Work on the SRS must therefore only
be performed by qualified technicians. Con-
tact an authorized Mercedes-Benz Center.
If it is necessary to modify an air bag system
to accommodate a person with disabilities,
contact your local authorized
Mercedes-Benz Center or call our Customer
Assistance Center at 1-800-FOR-MERCedes
(1-800-367-6372) for details.
