MERCEDES-BENZ ML350 2005 W163 Workshop Manual

49 Getting started
Driving
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.
For more information, see “Driving instruc-
tions” (
page 197).
For information on off-road driving, see
“Off-road driving” (
page 204).
!If you hear a warning signal when driv-
ing off, you have forgotten to release
the parking brake.
Release the parking brake.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.
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.!Simultaneously depressing the acceler-
ator pedal and applying the brake re-
duces engine performance and causes
premature brake and drivetrain wear.

For information on filling up the washer
reservoir, see “Windshield washer system
and headlamp cleaning system*”
(
page 230).
!Vehicles with rain sensor*:
Do not leave windshield wipers in inter-
mittent setting when the vehicle is tak-
en to an automatic car wash or during
windshield cleaning. Wipers will oper-
ate in the presence of water sprayed on
the windshield, and wipers may be
damaged as a result.
The switch should not be left in inter-
mittent setting as the wipers will wipe
the windshield once every time the en-
gine is started. Dust that accumulates
on the windshield might scratch the
glass and / or damage the wiper blades
when wiping occurs on a dry wind-
shield.

53 Getting started
Driving
Problems while driving
The engine runs erratically and misfires

An ignition cable may be damaged.


The engine electronics may not be
operating properly.


Unburned gasoline may have entered
the catalytic converter and damaged it.

Give very little gas.

Have the problem repaired by an au-
thorized Mercedes-Benz Light Truck
Center as soon as possible.The coolant temperature is above
248°F (120°C)
The coolant is too hot and is no longer
cooling the engine.

Stop the vehicle as soon as possible
and turn off the engine. Allow engine
and coolant to cool.

Check the coolant level and add cool-
ant if necessary (
page 227).In case of accident
If the vehicle is leaking gasoline:

Do not start the engine under any cir-
cumstances.

Notify local fire and / or police authori-
ties.
If the extent of the damage cannot be de-
termined:

Notify an authorized Mercedes-Benz
Light Truck Center.
If no damage can be determined on the


major assemblies


fuel system


engine mount:

Start the engine in the usual manner.

54 Getting startedParking and lockingYou have now completed your first drive.
You have properly stopped and parked
your vehicle. End your drive as follows.
Parking brake
1Parking brake
2Release handle
Step firmly on parking brake1.
When the engine is running, the warn-
ing lampÉ in the instrument clus-
ter will be illuminated.
Warning!
G
Wait until the vehicle is stationary before re-
moving the key from the steering lock. The
vehicle cannot be steered when the key 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
wheel towards the road curb.


Turn the key to steering lock position0
and remove.


Take the key and lock vehicle when leav-
ing.

55 Getting started
Parking and locking
Switching off headlamps
Turn the combination switch to1
(page 50).
For more information, see “Lighting”
(
page 107).
Turning off engine
Place the gear selector lever in
positionP.

Turn the key in the steering lock to
position0 (
page 33) and remove it.
The immobilizer is activated.

Move the steering wheel slightly to al-
low the locking mechanism to engage.
Warning!
G
When leaving the vehicle, always remove the
key from the steering lock and lock the vehi-
cle. Do not leave children unattended in the
vehicle, or with access to an unlocked vehi-
cle. Children could release the parking
brake and / or move the gear selector lever
from positionP, either of which could result
in an accident and / or serious personal
injury.
Warning!
G
Getting out of your vehicle with the gear
selector lever not fully engaged in positionP
is dangerous. Also, when parked on an in-
cline, positionP alone may not prevent your
vehicle from moving, possibly hitting people
or objects.
Always set the parking brake in addition to
shifting to positionP (
page 123).
When parked on an incline, also turn front
wheel towards the road curb.
iAlways set the parking brake in addi-
tion to shifting to positionP.
On steep slopes, turn the front wheels
towards the road curb.iThe key can only be removed from the
steering lock with the gear selector le-
ver in positionP.


56 Getting startedParking and locking
Press the seat belt release button
(page 43).
Allow the retractor to completely re-
wind the seat belt by guiding the latch
plate.
For more information, see “Locking and
unlocking” (

page 88).
iWith the key removed and the driver’s
door open, a warning sounds if the ve-
hicle’s exterior lamps are not switched
off.Warning!
G
When leaving the vehicle, always remove the
key from the steering lock, and lock your ve-
hicle. Do not leave children unattended in
the vehicle, or with access to an unlocked
vehicle. Unsupervised use of vehicle equip-
ment may cause an accident and / or seri-
ous personal injury.
Warning!
G
To prevent possible personal injury, always
keep hands and fingers away from the door
openings when closing the doors. Be espe-
cially careful when small children are
around.
Before closing doors, make sure there is no
possibility of someone getting caught in a
door during closing.

58 Safety and SecurityOccupant 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.The 1 indicator lamp in the instrument
cluster (
page 26) comes on for about
four seconds when you turn the key in the
steering lock to position1. It goes out
when you start the engine. This shows that
the restraint systems are operational.
If the lamp does not come on at all or if it
fails to extinguish after approximately four
seconds or if it comes on thereafter, a mal-
function in the system has been detected.
For more information, see the “Practical
hints” section (
page 262).
iFor information on infants and children
traveling with you in the vehicle and
restraint systems for infants and chil-
dren, see “Children in the vehicle”
(page 67).
Warning!
G
In the event that the 1indicator lamp
comes on during driving or does not come at
all, the SRS self-check has detected a mal-
function.
For your safety, we strongly recommend
that you visit an authorized Mercedes-Benz
Light Truck Center immediately to have the
system checked; otherwise the SRS may not
be activated when needed in an accident,
which could result in serious or fatal injury,
or it might deploy unexpectedly and unnec-
essarily which could also result in injury.
In addition, improper work on the SRS cre-
ates a risk of rendering the SRS inoperative
or causing unintended airbag deployment.
Work on the SRS must therefore only be per-
formed by qualified technicians. Contact an
authorized Mercedes-Benz Light Truck
Center.
