- Depending on the vehicle equipment, the
instrument lighting (for dials and needles)
may be switched on when the ignition is on
and the vehicle's lights are off. The illumi­
nation of the diaLs and needles is automati­
cally reduced as it becomes dark outside
and is eventually switched off altogether.

12, Fig. 3 only works when the ig­
nition is switched on. In order to avoid possible
damage to the engine, please read the following
notes for the different temperature ranges.
Engine cold
If the LEDs are still in the lower range of the dis­
play, this indicates that the engine has not yet
reached operating temperature. Avoid high en­
gine speeds, full acceleration and heavy engine

loads.

Normal temperature
The LEDs will settle somewhere in the centre of
the display once the engine has reached operat­
ing temperature. If the warning lamp || lights
up in the instrument cluster display, the coolant
temperature is too high

- Additional lights and other accessories in
front of the air inlet reduce the cooling ef­
fect of the radiator. At high outside temper­
atures and high engine loads, there is a risk
of the engine overheating.
- The front spoiler also ensures proper distri­
bution of the cooling air when the vehicle is

moving.
If the spoiler is damaged this can
reduce the cooling effect, which could cause
the engine to overheat. Obtain professional
assistance.
® Note
Applies to: vehicles with diesel engine
These engines are so efficient that they may
not reach their full operating temperature in
very cold weather. This is quite normal and no
cause for concern.
Rev counter

The
rev counter indicates the number of engine
revolutions per minute.
The start of the red zone on the dial indicates the
maximum engine speed which may be used brief­
ly in all gears when the engine is warm and after
it has been run in properly. However, it is advisa­
ble to change up a gear or move the selector lev­
er to D/S (or
lift your
foot
off
the accelerator) be­
fore the needle reaches the red zone. •

Note
After the engine is stopped, the radiator fan
may remain on or turn itself back on for up to
10 minutes, even if the ignition is switched
off. This may occur for the following reasons:
- Residual heat has raised the coolant
tem­

perature.
- Direct sunlight has additionally heated up
the engine compartment while the engine is

warm.

- Applies to vehicles with diesel particulate
filter: The emission control system is hot
because of the regeneration process, even
though the engine has
not
yet reached oper­
ating temperature.

® For the sake of the environment
Do not warm up the engine by running it with
the car stationary. You should drive off imme­
diately whenever possible. This will help avoid
unnecessary exhaust emissions.
© Note
- Any noises which may be heard when the
engine is started are quite normal and no
cause for concern.
- If
you
leave your vehicle with the ignition
switched on, it will be switched off auto­
matically after
a
while. Please note that
electrical equipment such as the exterior
lighting will also be switched off.

lock15

The steering will be locked if
you
switch off the
engine with the ISTART ENGINE STOP| button,
move the selector lever to position P (on vehicles
with automatic gearbox*) and open the driver's
door. The steering lock acts as a theft deterrent.
Emergency Off function
If necessary in an emergency, the engine can be
switched off while the vehicle is still moving at
speeds of 7 km/h and above. To switch off the
engine, press the ISTART ENGINE STOP| button
twice in quick succession or hold it in for longer
than two seconds.
A WARNING
- Never switch off the engine until the vehicle
is stationary. Otherwise you may not have
the full benefit of the brake servo and pow­
er steering. You may need more strength to
steer and brake the vehicle than you nor­
mally would. This would mean a greater risk
of accidents and serious injury, because you
cannot steer and brake in the normal
man­

ner.
- Always take the key with you when you Leave
the vehicle. Otherwise the engine can be
started or power-operated equipment such
as the electric windows can be used. This
could result in serious injury.
- When parking, always move the selector
lever to position
P
to prevent the vehicle
from rolling back accidentally.
If the engine has been working hard for
a
long

time,
there is a risk of heat building up in the
engine compartment after the engine has
been switched off; this could cause engine
damage. For this reason, you should leave the
engine idling for about 2 minutes before
switching it off.

a qualified workshop.
Electronic stabilisation control
The
ESC
-
in particular in conjunction with the
trailer stabilisation system
o^page
97 - makes
it

easier to stabilise a trailer
if it
starts to skid
or

sway. You should therefore keep the
ESC
switch­
ed on
at
all times.
Overheating
In hot weather, keep an eye on the coolant
tem­

perature gauge
^page
13. When climbing long
hills with the engine running fast in low gear, the
coolant temperature can increase. Reduce speed
immediately
if
the needle moves to the right end
of the scale. For information on the warning
lamp

Rear carrier systems
When using rear carrier systems (e.g. bicycle
racks) on the towing bracket,
it
is important not
to exceed the maximum load.
The total weight
of
the rear carrier system and
its

load must not exceed
75
kg for this vehicle. How­
ever,
it
is also important to observe the maxi­
mum permissible load for the rear carrier sys­

tem.

The greater the distance from the towing brack­
et, the smaller the maximum permissible Load
on

the rear carrier system. For this reason, you
should secure heavy objects as near as possible
to the towing bracket.
Note the instructions provided by the manufac­
turer of the rear carrier system.
Please make sure that the rear carrier system
is

approved for use on your vehicle.

l
Note
A WARNING
The use of an unsuitable rear carrier system
could cause severe damage
to
the towing
bracket. The towing bracket could then break
and cause an accident.
Degrease and clean the ball joint before using
a rear carrier system.

Removable towing
bracket

Introduction
Applies to: vehicles with removable towing bracket
Special care is required when fitting and remov­
ing the towing bracket.

Fig.
84 Luggage compartment:
Ball
joint for towing brack­
et (stowage example)
The removable ball joint attachment for the tow­
ing bracket is stored under the floor panel or in a
separate bag on the floor of the luggage com­
partment.
The ball joint can be fitted and removed by hand.
WARNING
Never use tools of any kind when fitting and
removing the ball joint. This could damage
the mechanism which locks the
ball
joint
in

place and impair its safety
-
risk of accident!
© Note
- Do not attempt to modify or repair the ball
joint or other towing bracket components.

Emission controL
systems
Catalytic converter
Applies to: vehicles with petrol engine
The vehicle must only be used with unleaded pet­

rol,
otherwise the catalytic converter will be ir­
reparably damaged.
Never allow the fuel tank to run completely dry,
as the irregular supply of fuel can cause misfir­

ing.
This allows unburnt fuel to enter the exhaust

system,
which can cause overheating and dam­
age to the catalytic converter.
Diesel particulate filter
Applies to: vehicles with diesel engine
The diesel particulate filter can filter out almost
all soot particles contained in the exhaust gas. In
normal driving conditions the filter is self-clean­

ing.
Should the self-cleaning function of the filter
not be able to operate, e.g. when the vehicle is
continuously used only for short trips, the filter
becomes obstructed with soot and the indicator

A WARNING
The exhaust system is very hot when the
vehi­

cle is being driven and after the engine has
been switched off.
- Never touch the tailpipes when they are hot
- risk of burns!
- Because of the high temperatures which can
occur in the emission controL system, do not
park the vehicle where the exhaust can
come into contact with flammable materials
under the car (e.g. on grass or at the forest
edge) - risk of fire!
- Do not apply any underseal agents in the
area around the exhaust system - risk of

fire!

Engine compartment
Working on components in the engine
compartment
Extra caution is necessary when working on com­
ponents in the engine compartment.
Always be aware of the danger of injury and
scalding as well as the risk of accident or fire
when working in the engine compartment (e.g.
when checking and refilling fluids). Always ob­
serve the warnings listed below and follow all
normal safety precautions. The engine compart­
ment of any motor vehicle is a potentially haz­
ardous area

- No additives should be used with engine oil.
Any damage caused by the use of such
addi­

tives would not be covered by the factory
warranty.
© For the sake of the environmen
- Never pour engine oil down drains or into
the ground.
-Always observe statutory requirements
when disposing of empty oil canisters.
© Note
Depending on
how
you drive and the condi­
tions in which the car is used, oil consumption
can be up to 0.5
Itr./lOOO
km. Oil consump­
tion is likely to be higher for the first 5,000

km.
The engine oil Level must be checked at
regular intervals, preferably when refuelling
and before setting off on a long trip.
Cooling system
Coolant
The engine cooling system is filled at the factory
with a mixture of conditioned water and coolant
additive. This coolant must not be changed.
The coolant level is monitored by a warning lamp
|
<^page
