out. The glow plug indicator light will come on for about 1 second if the engine is at a normal operating temperature
or if the outside temperature is above +5°C. This
means that you can start the engine
right away
.
There is a fault in the glow plug system if the
warning light
does not come on
at all
or lights up continuously
. Contact a specialist garage
as soon as possible to
obtain assistance. If the
warning light
begins
to flash
while driving, a fault exists in the engine
control. The engine management system
selects an emergency programme which
enables you to drive to the nearest specialist garage by adopting a gentle style of driving. The following text will be displayed in the information display*:

WARNING
•
If the brake system warning light
comes on together with the ABS
warning light
stop the vehicle immediatel
y and check the brake fluid
level in the reservoir
⇒page 167, “Brake fluid”. If the fluid level has dropped
below the MIN marking, do not drive any further - risk of accident! Obtain professional assistance.•
Pay attention to the following instru
ctions before checking the brake
fluid level and opening the bonnet
⇒page 160, “Working in the engine
compartment”.•
If the brake fluid is at
the correct level, the ABS control function has
failed. The rear wheels may then block ve
ry rapidly when braking. In certain
circumstances, this can result in the rear end of the car breaking away - risk of skidding! Drive carefully to the ne
arest specialist garage and have the
fault rectified.Traction control system (TCS) *
The warning light
comes on for a few seconds when the ignition is switched on.
The warning light flashes when a cont
rol cycle is activated while driving.
The warning light will come on and remains
on if the TCS is switched off or if there
is a fault in the system. The fact that the TCS system operates together with the ABS means that the TCS warning light will also come on if the ABS system is not operating properly. If the warning light
comes on immediately after starting the engine, the TCS
system can be switched off for technical
reasons. In this case, the TCS system can
be switched on again by swit
ching the ignition on and off. If the warning light goes
out, the TCS system is fully functional again. Further information about the TCS
⇒page 133, “Traction control system (TCS)”.
Electronic stability programme (ESP)*
The warning light
comes on for a few seconds when
the ignition is switched on.
Components of the ESP system also include the Traction Control System (TCS), the Electronic Differential Lock (EDL) and the Antilock Brake System (ABS). The warning light flashes when a control cycle is activated while driving.The warning light will come on and remains on
if the ESP is switched off or if there
is a fault in the system. The fact that the ESP system operates together with the ABS and the EDL means that the ESP warning light will also come on if
the ABS system is not operating properly.
If the warning light
comes on immediately after starting the engine, the ESP
system can be switched off for technical
reasons. In this case, the ESP system can
be switched on again by swit
ching the ignition on and off. If the warning light goes
out, the ESP system is fully functional again. Further information on the ESP
⇒page 131, “Electronic

Position
Move the steering wheel back and forward a little if the ignition key cannot, or cannot easily be turned into
this position, in order to
release the steering lock.
Position
The engine is started in this position. At
the same time switched on low beam or
main beam or other electrical compon
ents with major power consumption are
briefly switched off. The ignition key
moves back into position when one
releases the key. The ignition key must be turned back into position each time before starting the engine again. The starter repeat lock in th
e ignition lock prevents the starter being
engaged when the engine is r
unning and thus getting damaged.
WARNING
•
When driving, the ignition key must always be in the position (igni-
tion switched on) without the engine running. This position is indicated by the warning lights coming on. If this is not the case, it could result in unex- pected locking of the steerin
g wheel - risk of accident!
•
Do not withdraw the ignition key from the lock until the vehicle has come
to a stop. The steering lock can en
gage immediately - risk of accident!
•
Always withdraw the ignition key if
you are going to leave the vehicle,
even for a short time. This is particularly important if children are left in the vehicle. The children might
otherwise start the engine
or switch on electrical
equipment (e.g. power windows) - risk of accident or injury!Starting the engineGeneral You can only start the engine only using an original ignition key.•
Place the gearshift lever into neutral an
d put on the handbrake firmly before
starting the engine.•
The clutch pedal should be fully depr
essed when starting the engine - the
starter then only has to crank the engine.

WARNING
•
Never switch off the engine before the
vehicle is stationary - risk of acci-
dent!•
The brake booster only operates when the engine is running. Greater
physical effort for braking is required
when engine is switched off. Because
if you do not stop as normal, this can cause an accident and severe injuries.
Caution
you should not switch the engine off right
away at the end of your journey after the
engine has been operated fo
r a lengthy period at high
loads but should be allowed
it to run at idling speed for about 2 minutes
. This prevents any accumulation of heat
when the engine is switched off.
Note
•
The radiator fan may continue running fo
r a further 10 minutes or so after the
engine and the ignition have been switched
off. The coolant fan may, however, also
switch on again after some time if the coolant temperature rises because of an accumulation of heat in the engine or
if the engine is warm and the engine
compartment is additionally
heated by strong sunlight.
•
This is why particular care is required when carrying out any work in the engine
compartment
⇒page 160, “Working in the engine compartment”.
ShiftingShift into reverse only when the vehicle is
stationary. Depress the clutch pedal and
hold it fully depressed. Wa
it a moment before engaging reverse gear in order to
avoid any shift noises. The reversing lights will come on once reverse gear is engaged, provided the igni- tion is on.
WARNING
Never engage the reverse gear when driving - risk of accident!
Note
•
One should not lay the hand on the shift lever while driving the vehicle. The
pressure of the hand will be transferred to
the gearshift forks in the gearbox. This
can, over a period of time, lead to
early wear of the gearshift forks.
•
Depress the clutch pedal fully when chan
ging gears, in order to avoid unneces-
sary wear and damage.

an adequate field of view to the rear. Headlights Before starting off with a hitched trailer, also check the setting of the headlights. Alter the setting as necessary with th
e aid of the headlight beam adjuster
⇒ page 51. Detachable ball head The ball rod is detachable on vehicles which feature a factory-fitted towing device. It is stowed together with separate fitting instructions in the spare wheel well in the luggage compartment of the vehicle. Further information on the towing device
⇒page 146.
Note
•
We recommend that you also have yo
ur vehicle inspected between service
intervals if you tow a trailer frequently.•
The handbrake on the towing vehicle
must be put on when coupling and
decoupling the trailer.Driving Tips Particular caution is required when towing a trailer.– Do not, as far as possible, drive
with your vehicle unladen and the
trailer laden.
– Do not make full use of the legal maximum speeds. This applies in
particular to downhill sections.
– Apply the brakes in good time.– Keep a check on the coolant temper
ature gauge if the outside temper-
ature is high.
Distribution of weight The distribution of the weight is very poor
if your vehicle is
unladen and the trailer
is laden. Maintain a particularly low speed if you cannot avoid driving with this combination. Driving speed Do not drive faster than 80 km/hour for safety reasons. This also applies for coun- tries in which higher speeds are allowed. The fact that the driving stability of the vehicle + trailer combination reduces with increasing speed means that the legally allowed speed should not be used when there are unfavourable road, weather or wind
conditions, particul
arly near accident
black spots. You must always reduce your speed immedi
ately as soon as you detect even just
the
slightest swaying
of the trailer. On no account attempt to stop the trailer from
“swaying” by
accelerating.
Apply the brakes in good time! If the trailer is fitted with a
trailer brake
, apply the
brakes gently at first and then brake firmly
. This will avoid brake jolts resulting from
the trailer wheels locking. Shift down gears
in good time before negotiating a down-
hill section to allow the engine to also act as a brake. Engine overheating Please keep a check on the coolant temperature gauge if you have to negotiate a lengthy slope in a low gear at a high engine speed when the outside temperature is very high
⇒page 16.
If the needle of the coolant temperature gauge moves into the right-hand area or even the red area of the scale, reduce yo
ur speed immediately. Stop and switch off
the engine if the warning light
in the instrument cluste
r begins flashing. Wait a
few minutes and check the level of coolant in the coolant expansion bottle ⇒ page 165, “Inspecting the coolant level”. Please refer to the following guidelines
⇒page 30, “Coolant temperature/ Coolant
quantity
”.
The coolant temperature can be reduced by switching on the heating.Any increase in the cooling effect of the coolant fan through shifting down a gear and increasing the engine speed is not possible since the fan speed is independent
