2007 MERCEDES-BENZ CLS63AMG engine

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.

You have now completed your first drive.
You have properly stopped and parked
your vehicle. End your drive as follows.
Parking brake
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 ve-
hicle.Warning!
G
If you have selected the Comfort suspension
tuning (
page 231), the vehicle lowers
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.


Move the gear selector lever to
positionP.


Slowly release brake pedal.


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

TM air bag deactivation sys-
tem (
page 76)
Although independent systems, their pro-
tective functions work in conjunction with
each other.The SRS system conducts a self-test when
the ignition is switched on and in regular
intervals while the engine is running. This
facilitates early detection of malfunctions.
The 1indicator lamp in the instrument
cluster lights up when the ignition is
switched on and goes out no later than a
few seconds after the engine has been
started.
The SRS components are in operational
readiness if the 1indicator lamp is not
lit when the engine is running.
A malfunction in the system has been
detected if the 1indicator lamp:


fails to go out after approximately
4 seconds after the engine was started


does not come on at all


comes on after the engine was started
or while driving

72 Safety and SecurityOccupant safetyWarning!
G
If the 75 indicator lamp illumi-
nates when an adult or someone larger than
a small individual is in the front passenger
seat, have the front passenger re-position
himself or herself in the seat until the
75 indicator lamp goes out, or
check whether objects are caught under or
around the seat.
More information about air bag display mes-
sages (
page 362).
In the event of a collision, the air bag control
unit will not allow front passenger front
air bag deployment when the OCS classified
the front passenger seat occupant as being
up to or less than the weight of a typical
12-month-old child in a standard child re-
straint or if the front passenger seat is
sensed as being empty.
When the OCS senses that the front passen-
ger seat occupant is classified as being up
to or less than the weight of a typical
12-month-old child in a standard child re-
straint, the 75 indicator lamp
will illuminate when the engine is started
and remain illuminated, indicating that the
front passenger front air bag is deactivated.
When the OCS senses that the front passen-
ger seat is classified as being empty, the
75 indicator lamp will illumi-
nate when the engine is started and remain
illuminated, indicating that the front passen-
ger front air bag is deactivated.
When the OCS senses that the front passen-
ger seat occupant is classified as being
heavier than the weight of a typical
12-month-old child seated in a standard
child restraint or as being a small individual
(such as a young teenager or a small adult),
the 75 indicator lamp will illu-
minate for approximately 6 seconds when
the engine is started and then, depending on
occupant weight sensor readings from the
seat, remain illuminated or go out. With the
75 indicator lamp illuminated,
the front passenger front air bag is deacti-
vated. With the 75 indicator
lamp out, the front passenger front air bag is
activated.
