Lock cylinders
Designed to free-wheel if they are forcefully rotated without the correct
key or if the correct key is not fully
inserted. To reset, turn cylinder with
the correct key until its slot is vertical, remove key and then re-insert it. If the
cylinder still free-wheels, turn the key

20Keys, doors and windowsCar Pass
The Car Pass contains security
related vehicle data and should
therefore be kept in a safe place.
When the vehicle is taken to a
workshop, this vehicle data is needed
in order to perform certain operations.
Radio remote control
Used to operate: ● central locking system 3 23
● anti-theft locking system 3 33
● anti-theft alarm system 3 35
● load compartment 3 32
The remote control has a range of
approx. 5 metres. It can be restricted
by external influences. The hazard
warning flashers confirm operation.
Handle with care, protect it from
moisture and high temperatures and
avoid unnecessary operation.
Depending on model, the vehicle may
use a 2 button or 3 button remote
control or an electronic key which
includes the functionality of the radio
remote control.
Electronic key system 3 22.
Fault
If the central locking system cannot
be operated with the remote control,
it may be due to the following:
● range exceeded
● battery voltage too low
● frequent, repeated operation of the remote control while not in
range, which will require
reprogramming by a workshop● 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 key operation 3 23.
Remote control battery
replacement
Replace the battery as soon as the
range reduces.
Batteries do not belong in household
waste. They must be disposed of at
an appropriate recycling collection
point.
22Keys, doors and windowsElectronic key system
Enables a handsfree operation of thefollowing functions:
● central locking system 3 23
● load compartment 3 32
● ignition switching on and starting the engine 3 116
The electronic key simply needs to be on the driver's person.
Notice
Always take the electronic key with
you when exiting the vehicle.
The electronic key being left in the
card reader is indicated by a warning
chime 3 92 and a message in the
Driver Information Centre (DIC)
3 91 when the driver's door is
opened.
Additionally, the electronic key
includes the functionality of the radio
remote control 3 20 and an entry
lighting function 3 101.
Handle with care, protect from
moisture and high temperatures and
avoid unnecessary operation.
Notice
Do not put the electronic key in the
load compartment during driving, as
this is outside of the detection zone
(indicated by a warning chime at low
speed 3 92 and a message in the
Driver Information Centre (DIC)
3 91).
Handsfree operation is automatically disabled when the electronic key
buttons have been operated or the
central locking switch e 3 23 is
pressed. To re-enable handsfree
operation, restart the engine.
Power button 3 116.Replacing 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 DIC 3 91.
Battery replacement, see Radio
remote control 3 20.
Fault
If the central locking system cannot
be operated or the engine cannot be
started, the cause may be one of the
following:
● fault in electronic key
● electronic key out of reception range
● battery voltage 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

Starting the engine
Manual transmission: operate clutch.
Do not accelerate.
Diesel engines: turn the key to
position 2 for preheating until control
indicator ! extinguishes in the
instrument cluster 3 88.
Turn key to position 3 and release.
The increased engine speed
automatically returns to normal idling
speed as the engine temperature
rises.
Start attempts should not last longer
than 15 seconds. If engine does not
start, wait 15 seconds before
repeating starting procedure. If
necessary, depress accelerator
before repeating starting procedure.
Before restarting or to switch off the
engine, turn key back to 0.
During an Autostop, the engine can
be started by depressing the clutch
pedal. Stop-start system 3 119.
Turbo engine warm-up Upon start-up, engine available
torque may be limited for a short time,
especially when the engine
temperature is cold. The limitation is
to allow the lubrication system to fully protect the engine.Idle speed control
To increase the idle speed, press theswitch. After a few seconds the
function will be activated.
The function will be deactivated
when:
● The clutch pedal is depressed.
● The accelerator pedal is depressed.
● Vehicle speed is above 0 mph.
● Control indicator F, W or C
illuminate in the instrument
cluster.
To increase or decrease the fast idle
speed rate, consult a workshop.

166Vehicle careTyre pressure monitoring
system
The Tyre Pressure Monitoring
System (TPMS) uses radio and
sensor technology to check tyre
pressure levels.Caution
Tyre pressure monitoring system
warns only about low tyre pressure condition and does not replace
regular tyre maintenance by the
driver.
All wheels must be equipped with pressure sensors and the tyres must
have the prescribed pressure.
Notice
In countries where the tyre pressure
monitoring system is legally
required, the use of wheels without
pressure sensors will invalidate the
vehicle type approval.
The TPMS sensors monitor the air
pressure in the tyres and transmit tyre pressure readings to a receiver
located in the vehicle.
Tyre pressure chart 3 198.
Low tyre pressure condition
A detected low tyre pressure
condition is indicated by illumination
of control indicator w 3 88 and a
corresponding message appears in
the DIC.
If w illuminates, stop as soon as
possible and inflate the tyres as
recommended 3 198.
After inflating, some driving may be
required to update the tyre pressure
values in the system. During this time
w may illuminate.
If
w illuminates at lower temperatures
and extinguishes after some driving,
this could be an indicator for
approaching a low tyre pressure
condition. Check tyre pressure of all
four tyres.
If the tyre pressure must be reduced
or increased, switch off ignition.
Only mount wheels with pressure
sensors, otherwise w flashes for
several seconds then illuminates
continuously together with control
indicator F 3 86 and a corresponding
message appears in the DIC.
A spare wheel or temporary spare
wheel is not equipped with pressure
sensors. TPMS is not operational for
these wheels. For the further three
wheels, TPMS remains operational.
Control indicator w and the
corresponding message appears at
each ignition cycle until the tyres are
inflated to the correct tyre pressure.
Driver Information Centre (DIC) 3 90.
Vehicle messages 3 91.
Vehicle care167PunctureA puncture or severely under-inflated
tyre is indicated by illumination of
control indicator w together with C
3 86 and a corresponding message
appears in the DIC. Stop vehicle and
switch off engine.
Tyre pressure 3 198, Tyre repair kit
3 169, Spare wheel 3 173, Wheel
changing 3 171.
Relearn function
After a puncture has been repaired
and the driver has inflated the tyres to
the correct tyre pressure, TPMS
needs to recalculate.
Tyre pressure 3 198, Tyre repair kit
3 169.
During driving, select the tyre
pressure menu in the DIC by pressing button on end of wiper lever. Press
and hold button for approx.
5 seconds to initialise recalculation. A
corresponding message appears in
the DIC.
Several minutes of driving at a speed above 25 mph may be required tocomplete the relearn process. The
system can only provide limited
information during this time.
If problems occur during the relearn
process, control indicator w remains
illuminated and a warning message is
displayed in the DIC.
Driver Information Centre (DIC) 3 90.
Vehicle messages 3 91.
General information The use of tyre chains or
commercially available liquid tyre
repair kits can impair the function of
the system. Factory-approved tyre
repair kits can be used.Tyre repair kit 3 169, Tyre chains
3 168.
External high-power radio equipment
could disrupt the tyre pressure
monitoring system.
Each time the tyres are replaced,
TPMS sensors must be dismounted
and serviced by a workshop.
Tread depth
Check tread depth at regular
intervals.
Tyres should be replaced for safety
reasons at a tread depth of 2-3 mm
(4 mm for winter tyres).
For safety reasons it is recommended
that the tread depth of the tyres on
one axle should not vary by more than 2 mm.
