Fault
If the central locking system cannot
be operated with the radio remote
control, the cause may be one of the
following:
● Fault in radio remote control.● The range is exceeded.
● The battery voltage is too low.
● Frequent, repeated operation of the radio remote control while not
in range, which will require re-
synchronisation.
● Overload of the central locking system by operating at frequent
intervals, the power supply is
interrupted for a short time.
● Interference from higher-power radio waves from other sources.
Manual unlocking 3 25.Electronic key system
Enables a keyless operation of the
following functions:
● central locking system 3 25
● ignition switching on and starting the engine 3 131
The electronic key simply needs to be on the driver's person.
Additionally, the electronic key
includes the functionality of the radio
remote control 3 23.
Handle with care, protect from
moisture and high temperatures and
avoid unnecessary operation.
Keys, doors and windows25Replacing battery in electronic
key
Replace the battery as soon as the
system no longer operates properly or the range is reduced. The need for battery replacement is indicated by a
message in the Driver Information
Centre 3 98.
Batteries do not belong in household
waste. They must be disposed of at
an appropriate recycling collection
point.
1. Unclip the cover using a screwdriver in the cutout.
2. Remove the cover.
3. Extract the flat battery from its location.
4. Replace battery. Use CR 2032 or equivalent battery. Pay attention
to the installation position.
5. Clip the cover in place.
Fault
If the central locking cannot be
operated or the engine cannot be
started, the cause may be one of the
following:
● Fault in electronic key.
● Electronic key is out of reception range.
● The battery voltage is too low.
● Overload of the central locking system by operating at frequent
intervals, the power supply is
interrupted for a short time.
● Interference from higher-power radio waves from other sources.
To rectify the cause of the fault,
change the position of the electronic
key.
Manual unlocking 3 25.
Central locking system Unlocks and locks doors, load
compartment and fuel filler flap.
Pull an interior door handle fully to
unlock and open the respective door.
Driving and operating135● The driver's seat belt isunfastened and the driver's door
is opened.
● The engine temperature is too low.
● The charging level of the vehicle battery is below a defined level.
● The brake vacuum is not sufficient.
● The vehicle is driven at least at walking speed.
● The climate control system requests an engine start.
● The air conditioning is manually switched on.
If the bonnet is not fully closed, a warning message is displayed in the
Driver Information Centre.
If an electrical accessory, e.g. a
portable CD player, is connected to
the power outlet, a brief power drop during the restart might be noticeable.Parking9 Warning
● Do not park the vehicle on an
easily ignitable surface. The
high temperature of the
exhaust system could ignite the
surface.
● Always apply the parking brake. Activate the manual
parking brake without pressing the release button. Apply as
firmly as possible on a downhill slope or uphill slope. Depress
brake pedal at the same time to
reduce operating force.
● Switch off the engine.
● If the vehicle is on a level surface or uphill slope, engage
first gear or set the selector
lever to position P before
removing the ignition key or
switching off ignition on
vehicles with power button. On an uphill slope, turn the front
wheels away from the kerb.
If the vehicle is on a downhill
slope, engage reverse gear or
set the selector lever to position
P before removing the ignition
key or switching off ignition on
vehicles with power button.
Turn the front wheels towards
the kerb.
● Close the windows.
● Remove the ignition key from the ignition switch or switch off
ignition on vehicles with power
button. Turn the steering wheel until the steering wheel lock is
felt to engage.
● Lock the vehicle.
● Activate the anti-theft alarm system.
● The engine cooling fans may run
after the engine has been
switched off 3 177.
Caution
After running at high engine
speeds or with high engine loads,
operate the engine briefly at a low
142Driving and operatingIn manual mode, no automatic
shifting to a higher gear takes place
at high engine revolutions.
Gear shift indication
R with the number of a higher gear is
indicated, when upshifting is
recommended for fuel saving
reasons.
Shift indication appears only in
manual mode.
Electronic driving programmes
● Following a cold start, the operating temperature
programme increases engine
speed to quickly bring the
catalytic converter to the required
temperature.
● Special programmes automatically adapt the shifting
points when driving up inclines or
down hills.
● In snowy or icy conditions or on other slippery surfaces, the
electronic transmission controlenables the driver to select
manually first, second or third
gear for starting off.
Kickdown
Pressing down the accelerator pedal
beyond the kickdown detent will lead to maximum acceleration
independent of selected driving
mode. The transmission shifts to a lower gear depending on enginespeed.
Fault
In the event of a fault a message is
displayed in the Driver Information Centre. Vehicle messages 3 98.
Electronic transmission control
enables only third gear. The
transmission no longer shifts
automatically.
Do not drive faster than 100 km/h.
Have the cause of the fault remedied
by a workshop.Interruption of power supply
In the event of an interruption of
power supply, the selector lever
cannot be moved out of the P
position. The ignition key cannot be
removed from the ignition switch.
If the vehicle battery is discharged,
start the vehicle using jump leads
3 207.
If the vehicle battery is not the cause
of the fault, release the selector lever.
1. Apply the parking brake.
2. Release the selector lever trim from the centre console. Poke
with a finger into the leather
socket below the selector lever
and push the trim upwards.
182Vehicle careMeaning of symbols:● No sparks, naked flames or smoking.
● Always shield eyes. Explosive gases can cause blindness or
injury.
● Keep the vehicle battery out of reach of children.
● The vehicle battery contains sulphuric acid which could cause
blindness or serious burn
injuries.
● See the Owner's Manual for further information.
● Explosive gas may be present in the vicinity of the vehicle battery.
Diesel fuel system bleeding
If the tank has been run dry, the diesel
fuel system must be bled. Switch on
the ignition three times for
15 seconds at a time. Then crank the
engine for a maximum of
40 seconds. Repeat this process after
no less than five seconds. If the
engine fails to start, seek the
assistance of a workshop.Wiper blade replacement
Lift the wiper arm until it stays in the
raised position, press button to
disengage the wiper blade and
remove.
Attach the wiper blade slightly angled
to the wiper arm and push until it
engages.
Lower wiper arm carefully.
Wiper blade on the rear window
Lift wiper arm. Disengage wiper blade as shown in illustration and remove.
Attach the wiper blade slightly angled
to the wiper arm and push until it
engages.
Lower wiper arm carefully.
202Vehicle care9. Connect the compressor plug tothe power outlet or cigarette
lighter socket.
To avoid discharging the battery,
we recommend running the
engine.
10. Set the rocker switch on the compressor to I. The tyre is filled
with sealant.
11. The compressor pressure gauge briefly indicates up to 6 bar whilstthe sealant bottle is emptying
(approx. 30 seconds). Then the
pressure starts to drop.
12. All of the sealant is pumped into the tyre. Then the tyre is being
inflated.
13. The prescribed tyre pressure should be obtained within ten
minutes.
Tyre pressure 3 229.
When the correct pressure is
obtained, switch off the
compressor.
If the prescribed tyre pressure is
not obtained within ten minutes,
remove the tyre repair kit. Move
the vehicle one tyre rotation.
Reattach the tyre repair kit and
continue the filling procedure for
ten minutes. If the prescribed tyre
pressure is still not obtained, the
tyre is too badly damaged. Seek
the assistance of a workshop.
Drain excess tyre pressure with
the button on the air hose.
Do not run the compressor longer
than ten minutes.
14. Detach the tyre repair kit. Remove
sealant bottle from bracket. Screw the filler hose to the free
connection of the sealant bottle.
This prevents sealant from
escaping. Stow tyre repair kit in
load compartment.
15. Remove any excess sealant using a cloth.
