2004 MERCEDES-BENZ C320 4MATIC WAGON instrument cluster

45 Getting started
Driving

Release parking brake by pulling on
handle1.
The warning lamp; (USA only)
or3 (Canada only) in the
instrument cluster goes out.
Driving

Depress the brake pedal.

Move gear selector lever to positionD
orR.

Release the brake pedal.

Carefully depress the accelerator.
Once the vehicle is in motion, the auto-
matic central locking system engages
and the locking knobs drop down.After a cold start, the automatic transmis-
sion shifts at a higher engine revolution.
This allows the catalytic converter to reach
its operating temperature earlier.iWait for the gear selection process to
complete before setting the vehicle in
motion.
iYou can open a locked door from the
inside. Open door only when conditions
are safe to do so.
You can deactivate the automatic
locking using the control system
(page 131).
!Simultaneously depressing the
accelerator pedal and applying the
brake reduces engine performance and
causes premature brake and drivetrain
wear.!If you hear a warning signal when driv-
ing off, you have forgotten to release
the parking brake.
Release the parking brake.
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.!Place the gear selector lever in
positionR only when the vehicle is
stopped in order to avoid damaging the
transmission.!Do not run cold engine at high engine
speeds. Running a cold engine at high
engine speeds may shorten the service
life of the engine.

Parking and locking
Parking and locking
You have now completed your first drive.
You have properly stopped and parked
your vehicle. End your drive as follows.
Parking brake
1Release handle
2Parking brake
Step firmly on parking brake2.
When the engine is running, the
warning lamp; (USA only)
or3(Canada only) in the
instrument cluster will be illuminated.
Warning!
G
Wait until the vehicle is stationary before
removing the SmartKey from the starter
switch. The vehicle cannot be steered when
the SmartKey is removed.Warning!
G
With the engine not running, there is no
power assistance for the brake and steering
system. 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 as a re-
sult 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 to starter switch
position0 and remove.


Take the SmartKey and lock vehicle
when leaving.

56 Safety and SecurityOccupant safety
Occupant safetyIn this section you will learn the most im-
portant facts about the restraint systems
of the vehicle.
The restraint systems are

Seat belts


Emergency tensioning device


Airbags


Child seats


Child seat recognition


Lower anchors and tethers for children
(LATCH)
As independent systems, their protective
effects work in conjunction with each
other.The1 indicator lamp in the instrument
cluster (
page 22) comes on:


for about four seconds when you turn
the SmartKey in the starter switch to
position1.


for about four seconds when you start
the engine by turning the SmartKey.The1 indicator lamp goes out shortly
after you start the engine. This shows that
the restraint systems are operational.
A malfunction in the system has been
detected if the1 indicator lamp:


fails to extinguish after approximately
four seconds.


does not come on at all.


comes on after the engine was started
or while driving.
For safety reasons, we strongly recom-
mend that you visit an authorized
Mercedes-Benz Center immediately to
have the system checked.
For more information, see “Practical
hints”(
page 278).
iFor information on infants and children
traveling with you in the vehicle and
restraint systems for infants and
children, see “Children in the vehicle”
(page 65).
iThe1 indicator lamp remains lit if
the SmartKey is turned to position2
and left there. The indicator lamp will
go out when you start the engine.

74 Safety and SecurityDriving safety systems
Driving safety systemsIn this section you will find information on
the following driving safety systems:

ABS (A
ntilock B
rake S
ystem)


BAS (B
rake A
ssist S
ystem)


ESP (E
lectronic S
tability P
rogram)


4MATIC (Four Wheel Electronic
Traction System)
ABS
The Antilock Brake System (ABS) regulates
the brake pressure so that the wheels do
not lock during braking. This allows you to
maintain the ability to steer your vehicle.
The ABS is functional above a speed of ap-
proximately 5 mph (8 km/h) independent
of road surface conditions.
On slippery road surfaces, the ABS will
respond even with light brake pressure.
The- indicator lamp in the instrument
cluster (
page 22) comes on when you
turn the SmartKey in the starter switch to
position2. It goes out when the engine is
running.
iIn winter operation, the maximum
effectiveness of the ABS, ESP and
4MATIC (if so equipped) is only
achieved with winter tires (M + S tires),
or snow chains as required.
Warning!
G
The following factors increase the risk of
accidents:

Excessive speed, especially in turns


Wet and slippery road surfaces


Following another vehicle too closely
The ABS, BAS, ESP and 4MATIC (if so
equipped) cannot reduce this risk.
Always adjust your driving style to the
prevailing road and weather conditions.
Warning!
G
Do not pump the brake pedal. Use firm,
steady brake pedal pressure instead. Pump-
ing the brake pedal defeats the purpose of
the ABS and significantly reduces braking
effectiveness.
