Automatic locking and unlocking
All the doors and the luggage compartment lid are locked automatically once
the car reaches a speed of about 15 km/h.
If the ignition key is withdrawn, the car is then automatically unlocked again. It
is also possible for the driver to unlock the car by pressing the central locking
button.
The vehicle doors can be unlocked and opened at any time by pulling once on
the door opening lever.
Failure of the central locking
If the central locking system fails only the driver's door can be unlocked or
locked with the key. The other doors and the boot lid can be emergency locked
or unlocked.

Never leave the key in the vehicle when you exit the vehicle. Unauthor-
ized persons, such as children, for example, could lock the car, turn on the
ignition or start the engine - there is a danger of injury and accidents!■
When leaving the vehicle, never leave persons who are not completely in-
dependent, such as children, unattended in the vehicle. The children might,
for example, release the handbrake or take the vehicle out of gear. The ve-
hicle could then start to move – risk of injury and accidents! These individu-
als might also not be able to leave the vehicle on their own or to help
themselves. Can be fatal at very high or very low temperatures!
■
If the car is locked from the outside and the safelock system is switched
on, there must not be any person in the car as it is then not possible to
open either a door or a window from the inside. The locked doors make it
more difficult for rescuers to get into the vehicle in an emergency – risk to
life.
CAUTION
■ Each key contains electronic components; therefore it must be protected
against moisture and severe shocks.■
Keep the groove of the keys absolutely clean. Impurities (textile fibres, dust,
etc.) have a negative effect on the functionality of the locking cylinder and ig-
nition lock.
■
The battery must be replaced if the central locking does react to the remote
control at less than around 3 metres away » page 133.
■
When leaving the vehicle, always check if it is locked.■If the driver's door has been opened, the vehicle cannot be locked.
Note
In the event of an accident in which the airbags are deployed, the locked doors
are automatically unlocked in order to enable rescuers to gain access to the
vehicle.

of the indicator light in the button, the operational readiness of the cooling
system is signalled.
recirculation
Read and observe
and on page 70 first.
Recirculated air mode mostly prevents polluted air outside the vehicle fromgetting into the vehicle, for example when driving through a tunnel or when
standing in a traffic jam.
In recirculated air mode air is sucked out of the interior of the vehicle and then
fed back into the interior.

.
WARNINGThe recirculation system cannot be switched on for a longer period of time,
because there is no supply of fresh air from the outside. “Stale air” may re-
sult in fatigue in the driver and occupants, reduce attention levels and also
cause the windows to mist up. The risk of having an accident increases.
Switch off recirculated air mode as soon as the windows start to mist up.DCAUTIONWe recommend not smoking in the vehicle when the recirculating air operation
is switched on. The smoke sucked from inside the vehicle is deposited on the
evaporator of the air conditioner. This produces a permanent odour when the
air conditioning system is operating which can only be eliminated through con-
siderable effort and expense (replacement of compressor).
Efficient handling of the cooling system
Read and observe
and on page 70 first.
The air conditioning system compressor uses power from the engine when incooling mode, which will affect the fuel consumption.
It recommended to open the windows or the doors of a vehicle for which the
interior has been strongly heated through the effect of direct sunlight in order
to allow the heated air to escape.
The cooling system should not be on if the windows are open.
For the sake of the environment
Pollutant emissions are also reduced when fuel is saved » page 82.
malfunctions
Read and observe
and on page 70 first.
If the cooling system does not operate at outside temperatures higher than +5°C, there is a problem in the system. The reasons for this may be.
› One of the fuses has blown. Check the fuse and replace if necessa-
ry » page 135 .
› The cooling system has switched off automatically for a short time because
the coolant temperature of the engine is too hot » page 33.
If you are not able to resolve the operational problem yourself, or if the cooler
output has reduced, switch off the cooling system and seek assistance from a
specialist garage.
72Using the system

Driving off paved roadsRead and observe
on page 83 first.
Only drive on such roads and in such terrain, which match the vehicle parame-ters » page 143 , Technical data as well as your driving skills.
The driver is always responsible for deciding whether the vehicle can handle
travelling in the given terrain.
WARNINGDrive particularly aware and pro-actively outside paved roads.■Always adjust your driving to the current terrain and weather conditions.
Excessive speed or incorrect driving manoeuvres can cause damage to the
vehicle and lead to serious injuries.■
Objects trapped under the floor of the vehicle can damage the fuel lines,
the brake system, the seals and other parts of the chassis. Check the un-
derside of the vehicle and remove the trapped objects.
■
Combustible objects such as dry leaves or twigs caught under the base of
the vehicle could ignite on hot vehicle parts - risk of fire!
CAUTION
■ Pay attention to the ground clearance of the vehicle! When driving over ob-
jects which are larger than the ground clearance, the chassis and its compo-
nents can get damaged.■
Drive slowly in unknown terrain and watch out for unexpected obstacles,
such as potholes, rocks, stumps, etc.
■
Check up on confusing sections of unpaved roads before travelling on them
and consider whether such travelling is possible without risk.
Assist systems
Braking and stabilisation systems
Introduction
This chapter contains information on the following subjects:
Electronic Stability Control (ESC)
84
Antilock Braking System (ABS)
85
Traction Control System (TC)
85
Electronic Differential Lock (EDL)
85
Hydraulic Brake Assist (HBA)

Hill Hold Control (HHC)
85
This chapter deals with the functions of the braking and stabilisation systems,
with the error indicator referred to in chapter » page 33, Warning lights .
The braking and stabilisation systems are automatically activated each time the ignition is switched on.
WARNING■ A lack of fuel can cause irregular engine running or cause the engine to
shut down. The brake assist systems would then fail to function – risk of
accident!■
The increased safety provided by the brake assist systems must not
tempt you to take safety risks – risk of accident!
■
Adjust the speed and driving style to the current visibility, weather, road
and traffic conditions.
Electronic Stability Control (ESC)
Read and observe
on page 84 first.
The ESC improves vehicle stability in dynamic driving situations, such as whenthe vehicle starts to skid.
The ESC monitors whether the desired direction of the current vehicle motion
is occurring. In case of any deviation (e.g. oversteer), the ESC automatically
brakes individual wheels to maintain the desired direction.
During an intervention of the system, the warning light flashes in the instru-
ment cluster.
84Driving

Antilock Braking System (ABS)Read and observe
on page 84 first.
ABS prevents the wheels locking when braking. Thus helping the driver to
maintain control of the vehicle.
The intervention of the ABS is noticeable from the pulsating movements of
the brake pedal which is accompanied by noises.
When the ABS system is active, do not brake periodically or reduce the pres-
sure on the brake pedal.
Traction Control System (TC)
Read and observe
on page 84 first.
TCS prevents the spinning of the wheels of the driven axle. TCS reduces thedrive power transmitted to the wheels in the case of slipping wheels. Thus, for
example, driving on road surfaces with low grip is made easier.
If your vehicle is fitted with the ESC system, TC is integrated into the ESC sys-
tem » page 84 .
Note
For vehicles without stabilization control (ESC), during a TC-intervention the
control indicator in the instrument cluster flashes.
Electronic Differential Lock (EDL)
Read and observe
on page 84 first.
EDL prevents the turning of the respective wheel of the driven axle. EDL
brakes the spinning wheel, if necessary, and transmits the driving force to the
other driving wheel. Driving becomes easier on road surfaces with different
traction under each wheel of the driven axle.
The EDL switches off automatically in order to avoid excessive heat generation
on the brake of the wheel being braked. The vehicle can continue to be driven
and has the same characteristics as a vehicle not fitted with EDL. Once the
brakes have cooled down, there is an automatic re-activation of EDL.
Hydraulic Brake Assist (HBA)
Read and observe
on page 84 first.
HBA increases the braking effect and helps to shorten the braking distance.The HBA is activated by very quick operation of the brake pedal. In order to
achieve the shortest possible braking distance, the brake pedal must be ap-
plied firmly until the vehicle has come to a standstill.
The HBA function is automatically switched off when the brake pedal is re-
leased.
Hill Hold Control (HHC)
Read and observe
on page 84 first.
When driving on slopes, HHC allows you to move your foot from the brake ped-al to the accelerator pedal without having to use the handbrake.
The system holds the brake pressure produced by the activation of the brake pedal for approx. 2 seconds after the brake pedal is released.
The brake pressure drops gradually the more you operate the accelerator ped-
al. If the vehicle does not start off within 2 seconds, it starts to roll back.
The HHC is active as of a 5 % slope, if the driver door is closed. HHC is always
only active on slopes when in forward or reverse start off.

The Cruise Control System (CCS) maintains a set speed without you having to
actuate the accelerator pedal.
The state where the GRA maintains the speed is referred to hereinafter as the
control .
ABCDWARNING■
The GRA only serves to support and does not relieve the driver of the re-
sponsibility for the vehicle operation.■
Always adjust the speed and driving style to the current visibility, weath-
er, road and traffic conditions.
Functioning
Read and observe
on page 87 first.
Basic requirements for start of control The GRA is activated.
On vehicles with a manual transmission , the second gear or higher must
be engaged.
On vehicles with an automatic transmission , the selector lever must be in
the D position or in the Tiptronic position.
The current speed must be higher than 20 km/hr.
This is only possible within the range which is permitted by the power output and braking power of the engine.
WARNINGIf the engine power and engine braking effect is insufficient to maintain
the set speed, vehicle operation must be taken over!
