Vehicles with a petrol engine:
–Use the foot brake.
– Manual gearbox: Push the clutch pedal all the way down.
– Move the gear lever into neutral (automatic gearbox: selector
lever to P or N) ⇒
.
– Turn the ignition key to position 3
without pressing the accel-
erator.
– Release the ignition key as soon as the engine starts (the start-
er motor must not be allowed to run on with the engine).
Vehicles with a diesel engine:
– Use the foot brake.
– Manual gearbox: Push the clutch pedal all the way down. Other-
wise, the engine will not start.
– Move the gear lever into neutral (automatic gearbox: selector
lever to P or N) ⇒
.
– Turn the ignition key to position 2
. The pre-heating indicator
light comes on while the glow plugs are preheating.
– When the indicator light
goes out, turn the ignition key to
position 3
. Do not press the accelerator.
– Having completed the previous action the key can be released
immediately, it will return to position 2
and the engine will
have started.
When starting a very cold engine, it may be a little noisy for the first few sec-
onds until oil pressure has built up in the hydraulic valve compensators.
This is quite normal, and no cause for concern. If the engine fails to start straight away, stop after 10 seconds and try again
after about half a minute.
Glow plug system*
To assist starting at low temperatures,
diesel engines are equipped with a
glow plug preheating system. The preheating time depends on the coolant
temperature and the outside temperature. Start the engine as soon as the
glow plug indicator light goes out.
When the engine is warm or at outside temperatures above +8 °C, the glow
plug indicator light will only come on for about one second. This means that
the engine can be started immediately.
If the engine will not start...

WARNING
Never run the engine in confined spaces, as the exhaust gases are poi-
sonous.
CAUTION
Avoid high engine speeds, full throttle and extreme load conditions until
the engine has reached its normal operating temperature, otherwise this
can damage the engine.
For the sake of the environment
Do not warm up the engine by running the engine with the vehicle station-
ary. Start immediately. This will help avoid unnecessary exhaust emissions.

Driving
Stopping the engine
– Turn the ignition key to position 1 ⇒ fig. 148.
WARNING
● Never switch the engine off until the vehicle is stationary.
● The brake servo and the power steering system work only when the
engine is running. You need more strength to steer and brake the vehicle
when the engine is switched off. Given that you will be unable to steer
and brake as usual, this could lead to a risk of accidents and injuries.
CAUTION
If the engine has been running under high load 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. Therefore, you should
let the engine idle for approximately 2 minutes before you switch it off.
Note
After the engine is switched off the radiator fan may run on for up to 10 mi-
nutes, even if the ignition is switched off. It may also start running again af-
ter some time if the coolant temperature rises due to a build-up of heat un-
der the bonnet, or if the engine is already warm and the engine compart-
ment is heated up further by direct sunlight. Handbrake
Handbrake
The handbrake should be applied firmly to prevent the vehi-
cle from accidentally rolling away.

Selector lever lock
The selector lever lock prevents gears from being engaged
inadvertently, so that the vehicle is not set in motion unin-
tentionally.
Fig. 156 Selector lever
lock functions
The selector lever lock is released as follows:
– Switch the ignition on.
– Press the brake pedal and at the same time press in the inter-
lock button.
Automatic selector lever lock
With the ignition turned on, the selector lever is locked in the positions P
and N. To remove it from these positions, press on the brake. The following
message appears in the instrument panel as a reminder for the driver when
the selector lever is in position P or N: WHEN STATIONARY APPLY FOOTBRAKE WHILE SELECTING GEAR The selector lever lock only works if the vehicle is stationary or driving at
speeds up to 5 km/h. At higher speeds the selector lever lock in the N posi-
tion is disengaged automatically.
The selector lever lock is not engaged if the selector lever is moved quickly
through position N (e.g. when shifting from R to D). This makes it possible,
for instance, to “rock” the vehicle backwards and forwards if it is stuck in
snow or mud. The selector lever lock engages automatically if the brake
pedal is not depressed and the lever is in position N for more than about a
second.
Interlock button
The interlock button on the selector lever handle prevents the driver from
inadvertently engaging particular gears. Press the button in to disengage
the selector lever lock. The selector lever positions in which the interlock
button has to be pressed are shown in the illustration, highlighted in colour
⇒
fig. 156.
Safety interlock for ignition key
Once the ignition has been turned off, the key may be removed only if the
gear selector is in position P. While the key is not in the ignition, the selec-
tor lever is locked in position P.
Kick-down feature
This feature allows maximum acceleration. Vehicles with multitronic ®
gearbox
When the accelerator pedal is pressed right down past the point of resist-
ance at full throttle, the gearbox will select a lower gear ratio, depending on
road speed and engine speed. While you keep the accelerator depressed
the engine speed is automatically controlled to give your vehicle maximum
acceleration.
202Trailer towing
Where possible, operate the trailer with the maximum permitted drawbar
load on the ball joint of the towing bracket, but do not exceed the specified
limit.
Tyre pressure
Check the tyre pressures on your vehicle, and adjust for “full load” condi-
tions (refer to the sticker listing the tyre pressures on the door pillar). It may
also be necessary to adjust the tyre pressures on the trailer according to the
recommendations of the trailer manufacturer.
Exterior mirrors
Check whether you can see enough of the road behind the trailer with the
standard mirrors. If this is not the case you should have additional mirrors
fitted. The two exterior mirrors should be fitted on folding arms. Adjust the
mirrors to give sufficient rear vision.
Headlights
Before starting a journey, check the headlight beam settings with the trailer
hitched up. If necessary, alter the height of the headlight beams by means
of the headlight range control. See ⇒ page 119.
Power supply
When you remove the ignition key, the power supply to the trailer is inter-
rupted.
Removable ball joint coupling
Vehicles with a factory-fitted towing bracket are equipped with a removable
ball joint coupling. This is stored in the spare wheel well in the luggage
compartment together with the necessary fitting instructions.
Note
If you frequently tow, we recommend you also have the vehicle serviced be-
tween services. Notes on towing
Towing a trailer involves additional attention by the driver.
Weight distribution
The weight distribution of a loaded trailer with an unladen vehicle is very
unfavourable. However, if this cannot be avoided, drive extra slow to allow
for the unbalanced weight distribution.
Speed
The stability of the vehicle and trailer is reduced with increasing speed.
Therefore, it is advisable not to drive at the maximum permissible speed in
unfavourable road, weather or wind conditions. This especially applies
when driving downhill.
You should always reduce speed immediately if the trailer shows the slight-
est sign of swaying. Never try to stabilise the trailer by accelerating.
Anticipate hazards and brake in good time. If towing a trailer with an inertia
brake, first brake gently and then harder. This will prevent brake tapping by
the trailer wheels when they lock. Select a low gear in due course before go-
ing down a steep downhill. This enables you to use the engine braking to
slow down the vehicle.
Swaying and pitching can be reduced by stabiliser aids. We recommend
having stabiliser aids installed when towing trailers with a high trailer
weight. They can be purchased and installed at a Technical Service.
Reheating
When climbing long hills in hot weather with the engine running fast in low
gear, you should keep an eye on the coolant temperature gauge ⇒ page 60.
Reduce speed immediately if the needle moves to the right end of the scale.
If the temperature warning lamp in the instrument panel should start
flashing, stop the vehicle and let the engine cool down by running it at
idling speed for a few minutes.

Vehicle maintenance and cleaning
Vehicle maintenance and cleaning General notes
Regular washing and care help maintain the value of your
vehicle.Vehicle maintenance
Regular care and washing help to maintain the value of the vehicle. This
may also be one of the requirements for acknowledging warranty claims in
the event of bodywork corrosion or paint defects.
The best way to protect your vehicle against the harmful effects of the envi-
ronment is through correct maintenance and frequent washing. The longer
substances such as insect remains, bird droppings, resinous tree sap, road
dirt, industrial deposits, tar, soot or road salt and other aggressive materi-
als remain on the vehicle, the more damage they do to the paintwork. High
temperatures (for instance in strong sunlight) further intensify the corrosive
effect.
After winter, a period when salt is put on the roads, it is important to have
the underside of the vehicle washed thoroughly.
Products for vehicle maintenance
Car care products are available in your Authorised Service Centre. Keep the
product instructions until you have used them up.
WARNING
● Car care products can be toxic. Because of this, they must always be
kept closed in their original container. Keep them out of the reach of chil-
dren. Failure to comply could result in poisoning.
● Always read and observe the instructions and warnings on the pack-
age before using vehicle care products. Improper use could cause health
problems or damage the vehicle. The use of certain products may pro-
duce noxious vapours; they should be used in well ventilated areas.
● Never use fuel, turpentine, engine oil, nail varnish remover or other
volatile fluids. These are toxic and highly flammable. Risk of fire and ex-
plosion.
● Before washing your vehicle, or carrying out any maintenance, switch
the engine off, apply the handbrake firmly and remove the key from the
ignition.
CAUTION
Never attempt to remove dirt, mud or dust if the surface of the vehicle is dry.
Never use a dry cloth or sponge for cleaning purposes. This could damage
the paintwork or the windows of your vehicle. Soak dirt, mud or dust with
plenty of water.
For the sake of the environment
● When purchasing products for your vehicle maintenance, select the
ones which are not harmful to the environment.
● The waste from car care products should not be disposed of with ordina-
ry household waste. Observe the disposal information on the package.
