door lock MERCEDES-BENZ CLS550 2007 W219 User Guide

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.

cally after major steering wheel move-
ments.

Do not operate the wipers when the wind-
shield is dry. Dust that accumulates on a wind-
shield might scratch the glass and/or damage
the wiper blades when wiping occurs on a dry
windshield. If it is necessary to operate the wip-
ers in dry weather conditions, always operate
the wipers with windshield washer fluid
(
page 58).

82 Safety and SecurityOccupant safetyAutomatic comfort-fit feature seat belt
An automatic comfort-fit feature for front
seats reduces the retracting force of the
seat belts when they are in normal use.
Preventive occupant safety (PRE-SAFE
®)Your vehicle automatically takes preven-
tive measures to better protect the occu-
pants in the following hazardous
situations:


You execute an emergency braking ma-
neuver and the Brake Assist System
(page 92) is activated.


The PRE-SAFE
® system detects a criti-
cal driving dynamics situation.
In such cases, the following systems are
automatically activated:


The front seat belts are pre-tensioned
electrically.


If the vehicle is in a severe skid or is
spinning, the door windows and the
tilt/sliding sunroof close until a small
gap remains.Vehicles with front passenger seat memo-
ry function*:


If the seat is in an unfavorable position,
it will be adjusted to a better position.
If the seat belts do not release:

Adjust the backrest or seat slightly to
the rear until the seat belt tension is di-
minished.
The locking mechanism releases.
Warning!
G
The PRE-SAFE
® system is intended to re-
duce the effects of a crash on properly
seat-belted vehicle occupants. Despite hav-
ing the PRE-SAFE® system in your vehicle,
the possibility of injuries occurring as a re-
sult of an accident cannot be eliminated.
Therefore, you should always drive carefully
and adjust your driving to the prevailing
road, weather, and traffic conditions.
i
If the closing procedure of the tilt/sliding
sunroof or door window is blocked, the tilt/slid-
ing sunroof or door window will stop and open
slightly.
i
The PRE-SAFE
® system is activated in the
previously described circumstances only at
speeds exceeding 20 mph (30 km/h).
When the critical driving dynamic situation has
passed without an accident occurring, the
pre-tensioning on the seat belts is deactivated.
You can then adjust the seat, the door windows
and the tilt/sliding sunroof to their previous po-
sition.

84 Safety and SecurityOccupant safetyChildren in the vehicle
If an infant or child is traveling with you in
the vehicle:
Secure the child using an infant or child
restraint appropriate to the age and
size of the child.

Make sure that the infant or child is
properly secured at all times while the
vehicle is in motion.
Infant and child restraint seats and
information on choosing an appropriate
restraint system can be obtained from any
Mercedes-Benz Center.Infant and child restraint systems
We recommend all infants and children be
properly restrained at all times while the
vehicle is in motion.
Canada only:
Use only a BabySmart
TM compatible child
restraint for the front passenger seat in
this vehicle.
All lap-shoulder belts except the driver’s
seat belt have special seat belt retractors
for secure fastening of child restraints.
To fasten a child restraint, follow child
restraint instructions for mounting. Then
pull the shoulder belt out completely and
let it retract. During seat belt retraction, a
ratcheting sound can be heard to indicate
that the special seat belt retractor is acti-
vated. The seat belt is now locked. Push
down on child restraint to take up any
slack.
To deactivate, release seat belt buckle and
let seat belt retract completely. The seat
belt can again be used in the usual
manner.

G
Do not leave children unattended in the
vehicle, even if they are secured in a child
restraint system. The children could

injure themselves on parts of the vehicle


be seriously or fatally injured through
exposure to extreme heat or cold
Do not expose the child restraint system to
direct sunlight. The child restraint system’s
metal parts, for example, could become very
hot, and the child could be burned on these
parts.
If children open a door, they could

injure other persons


get out of the car and injure themselves
or be injured by following traffic
Do not carry heavy or hard objects in the
passenger or cargo compartment unless
they are firmly secured in place. For more in-
formation, see “Loading” (
page 239) and
“Useful features” (
page 244).
Unsecured or improperly positioned cargo

When leaving the vehicle, always remove the
SmartKey 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. It is possible
for children to open a locked door from the

and/or serious personal injury.i
When you open a door, the side window on
that side lowers slightly. Once you close the
door, the window moves up again.

The side windows will not open or close if
the battery is discharged or the windows are cov-
ered with ice. As a result, you may no longer be
able to properly close the door. Do not attempt
to force the door shut. Doing so may damage the
door or the side window. Correct the condition
that prevents the windows from operating before
attempting to close the door.
