Driving
Always apply the handbrake when you leave your vehicle and when
you park.
Applying the handbrake
– Pull the handbrake lever up firmly ⇒ Fig. 122.
Releasing the handbrake
– Pull the lever up slightly and press the release knob in the di-
rection of the arrow ⇒ Fig. 122 and guide the handbrake lever
down fully ⇒
.
Always apply the handbrake as far as it will go in order to prevent yourself
from driving with the handbrake applied by mistake ⇒
.
The handbrake warning lamp lights up when the handbrake is applied
and the ignition switched on. The warning lamp turns off when the hand-
brake is released.
WARNING
● Never use the handbrake to stop the vehicle when it is in motion. The
braking distance is considerably longer, because braking is only applied
to the rear wheels. Risk of accident!
● If the handbrake is only partially released, this will cause the rear
brakes to overheat, which can impair the function of the brake system
and could lead to an accident. This also causes premature wear on the
rear brake pads.
CAUTION
Always apply the handbrake before you leave the vehicle. The first gear
should also be selected. Parking
The handbrake should always be firmly applied when the
vehicle is parked.
Always note the following points when parking the vehicle:
–
Use the brake pedal to stop the vehicle.
– Apply the handbrake.
– Select first gear.
– Switch the engine off and remove the key from the ignition. Turn
the steering wheel slightly to engage the steering lock.
– Always take you keys with you when you leave the vehicle ⇒
.
Additional notes on parking the vehicle on gradients:
Turn the steering wheel so that the vehicle rolls against the kerb if it started
to roll.
● If the vehicle is parked facing downhill, turn the front wheels so that
they point towards the kerb .
● If the vehicle is parked facing uphill, turn the front wheels so that they
point away from the kerb .
● Secure the vehicle as normal by applying the handbrake firmly and se-
lecting first gear.

Front parking aid
The parking aid system will sound an audible warning to in-
dicate of the approach of any object towards the front or
rear of the vehicle.
Description
The acoustic parking aid system measures the distance between the vehicle
and any possible obstacle using 8 ultrasonic sensors (4 of which are loca-
ted on the rear bumper and 4 of which are located on the front bumper).
The measuring range of the sensors starts approximately and depending on
the nature of the obstacle at a distance of:
● side of the front bumper: 0.6 m
● middle of the front bumper: 1.2 m
● side of the rear bumper: 0.6 m
● middle of the rear bumper: 1.6 m
Activation
The system may be activated in the following ways:
● Engage the reverse gear (a brief, sharp acoustic signal confirms activa-
tion and the correct operation of the system) or
● Push the central console button (a brief confirmation signal will
sound and the button’s LED will light up).
Disconnection
The system may be deactivated in the following ways:
● Drive forwards at more than approx. 10 km/h (6 mph) or else
● Press the button, or
● Switch the ignition off Manoeuvres
The distance warning will begin as soon as an obstacle is detected in the
system's field of detection (front and rear). The frequency of the bleeps
emitted by the system will increase rapidly as the vehicle approaches the
obstacle. Two speakers, one in the front and one in the rear, indicate the lo-
cation of the obstacle (either front or rear).
After a distance lower than approximately 30 cm, a continuous signal
sounds (stop signal). At this point the driver should halt the vehicle.
Models with a factory-fitted towing bracket: When the vehicle is less than
0.35 m away from the obstacle the warning tone will sound continuously.
The driver should then not reverse any further.
The warning tone volume decreases by 30% 3 seconds after it is triggered if
the detected obstacle stays at a constant distance from the vehicle.
Provided that it is not in continuous mode, the tone on the parking aid sys-
tem stops when it detects a wall parallel to the vehicle.
Trailer towing
For vehicles factory-fitted with a towing bar, the parking aid system will not
be activated by the engagement of the reverse gear when pulling a trailer,
as the trailer's electric connector will be plugged into the vehicle.
Possible faults
If a continuous, sharp beep sounds for various seconds, there is a fault in
the parking aid system.
If the fault continues until the ignition is turned off, the audible warning of
the fault will not be emitted every time the system is reactivated (by engag-
ing the reverse gear or pressing the button). Thus, the system ready indi-
cation will not sound either. Have the fault repaired by a Technical Service
as soon as possible.
If there is no ready signal or no acoustic warning signal, then the parking
aid loudspeaker is faulty and may not warn of obstacles. To ensure that the

Cruise speed* (Cruise control system)
Description
The CCS is able to maintain the set speed in the range from
approx. 30 km/h (19 mph) to 180 km/h (112 mph). Once the speed setting has been saved, you may take your foot off the ac-
celerator.
WARNING
It could be dangerous to use the cruise control system if it is not possible
to drive at constant speed.
● Do not use the cruise control system when driving in dense traffic, on
roads with lots of bends or on roads with poor conditions (with ice, slip-
pery surfaces, loose grit or gravel), as this could cause an accident.
● Always switch the cruise control system off after using it in order to
avoid involuntary use.
● It is dangerous to use a set speed which is too high for the current
road, traffic or weather conditions. Risk of accident.
Note
The cruise control cannot maintain a constant speed when descending
downhill. The vehicle will accelerate due to its own weight. Use the foot
brake to slow the vehicle. Switching the cruise control system on and off

– Press the lower part SET of the rocker switch ⇒ Fig. 126 B
once
briefly when you have reached the speed you wish to set.
When you release the rocker switch, the current speed is set and held con-
stant.
Adjusting set speed*
The speed can be altered without touching the accelerator or
the brake. Setting a higher speed
– Press the upper part RES of the rocker switch ⇒ Fig. 126 B
to
increase the speed. The vehicle will continue to accelerate as
long as you keep the rocker switch pressed. When you release
the switch, the new speed is stored. Setting a lower speed
–
Press the lower part SET– of the rocker switch ⇒ Fig. 126 B
to
reduce the speed. The vehicle will automatically reduce its
speed for as long as you keep the switch pressed. When you re-
lease the switch, the new speed is stored.
When you increase speed with the accelerator and then release the pedal,
the system will automatically restore the set speed. This will not be the
case, however, if the vehicle speed is more than 10 km/h (6 mph) higher
than the stored speed for longer than 5 minutes. The speed will have to be
stored again.
Cruise control is switched off if you reduce speed by depressing the brake
pedal. Reactivate the control by pressing once on the upper part of the rock-
er switch RES+ ⇒ Fig. 126 B

Practical Tips
Intelligent technology
Brakes Brake servo
The brake servo increases the pressure you apply to the brake pedal. It
works only when the engine is running .
If the brake servo is not functioning due to a malfunction, or if the vehicle
has to be towed, you will have to press the brake pedal considerably harder
to make up for the lack of servo assistance.
WARNING
The braking distance can also be affected by external factors.
● Never let the vehicle coast with the engine switched off. Failure to do
so could result in an accident. The braking distance is increased consid-
erably when the brake servo is not active.
● If the brake servo is not working, for example when the vehicle is be-
ing towed, you will have to press the brake pedal considerably harder
than normal.
Hydraulic Brake Assist (HBA)*
The function (Hydraulic Brake Assist HBA) is only included in
vehicles with ESC.
In an emergency, most drivers brake in time, but not with maximum force.
This results in unnecessarily long braking distances.
This is when the brake assist system comes into action. When pressing the
brake pedal rapidly, the assistant interprets it as an emergency. It then very
quickly builds up the full brake pressure so that the ABS can be activated
more quickly and efficiently, thus reducing the braking distance.
Do not reduce the pressure on the brake pedal. The brake assist system
switches off automatically as soon as you release the brake.
Automatic hazard warning lights activation
The brake lights flash automatically to indicate that the vehicle is braking
suddenly or in an emergency situation. If the emergency braking continues
until the vehicle comes to a standstill, the hazard warning lights will then
come on and the brake lights will remain on permanently from that moment.
The warning lights will automatically switch off when the vehicle begins to
move again or when the "warning" light button is pressed.
177
Intelligent technology
Electronic Stability Control (ESC)*
The ESC reduces the risk of skidding by braking the wheels individually.
The system uses the steering wheel angle and road speed to calculate the
changes of direction desired by the driver, and constantly compares them
with the actual behaviour of the vehicle. When irregularities occur, for exam-
ple, if the vehicle begins to skid, the ESC brakes the appropriate wheel au-
tomatically.
The forces acting on the braked wheel bring the vehicle back to a stable
condition. If the vehicle tends to oversteer, the system will act on the front
wheel on the outside of the turn.
WARNING
● Remember that not even the ESC can defy the laws of physics. This
should be kept in mind, particularly on slippery and wet roads and when
towing a trailer.
● Always adapt your driving style to suit the condition of the roads and
the traffic situation. The greater safety provided by the ESC should not
encourage you to run any risks.
CAUTION
● To ensure that the ESC works correctly, all four wheels must be fitted
with the same tyres. Any differences in the rolling radius of the tyres can
cause the system to reduce engine power when this is not desired.
● Any modifications made to the vehicle (for example, to the engine,
brake system, running gear or to the combination of wheels and tyres) may
affect the operation of the ABS, EDL, ESC and ASR. Anti-lock brake system (ABS)
The anti-lock brake system prevents the wheels locking during braking
⇒ page 175
Electronic differential lock (EDL)*
The electronic differential lock helps prevent the loss of trac-
tion caused if one of the driven wheels starts spinning.
EDL helps the vehicle to start moving, accelerate and climb a gradient in
slippery conditions where this may otherwise be difficult or even impossi-
ble.
The system will control the revolutions of the driven wheels using the ABS
sensors (in case of an EDL fault the warning lamp for ABS lights up)
⇒ page 71.
At speeds of up to approximately 80 km/h (50 mph), it is able to balance
out differences in the speed of the driven wheels of approximately 100 rpm
caused by a slippery road surface on one side of the vehicle. It does this by
braking the wheel which has lost traction and distributing more driving
force to the other driven wheel via the differential.
To prevent the disc brake of the braking wheel from overheating, the EDL
cuts out automatically if subjected to excessive loads. The vehicle will con-
tinue to function normally without EDL. For this reason, the driver is not in-
formed that the EDL has been switched off.
The EDL will switch on again automatically when the brake has cooled
down.
Safety FirstOperating instructionsPractical TipsTechnical Specifications
180Driving and the environment
recommend that you have the thickness of your brake pads checked by a
Technical Service more frequently than recommended in the Maintenance
Programme.
If you drive with wet brakes, for example, after crossing areas of water, in
heavy rainfall or even after washing the vehicle, the effect of the brakes is
lessened as the brake discs are wet or even frozen (in winter). In this case
the brakes should be dried by pressing the brake pedal several times.
WARNING
Longer braking distances and faults in the brake system increase the risk
of accidents.
● New brake pads must be run in and do not have the correct friction
during the first 200 km. However, the reduced braking capacity may be
compensated by pressing on the brake pedal a little harder. This also ap-
plies when the brake pads have to be changed further on.
● If brakes are wet or frozen, or if you are driving on roads which have
been salted, braking power may be lower than normal.
● On steep slopes, if brakes are excessively used, they will overheat.
Before driving down a long steep slope, it is advisable to reduce speed
and change down into a lower gear or range (depending on the type of
transmission). This makes use of engine braking and relieves the brakes.
● Never let the brakes “drag” by applying light pressure. Continuous
braking will cause the brakes to overheat and the braking distance will
increase. Apply and then release the brakes alternately.
● Never let the vehicle run with the engine switched off. The braking
distance is increased considerably when the brake servo is not active.
● If the brake fluid loses its viscosity and is subjected to heavy use, va-
pour bubbles can form in the brake system. This reduces the efficiency of
the brakes.
WARNING (Continued)
● Non-standard or damaged front spoilers could restrict the airflow to
the brakes and cause them to overheat. Before purchasing accessories
please observe the relevant instructions ⇒ page 196, Technical modifi-
cations.
● If a brake system circuit fails, the braking distance will be increased
considerably. Contact a specialised workshop immediately and avoid un-
necessary journeys.
Exhaust gas purification system Catalytic converter*
To maintain the useful life of the catalytic converter
– Use only unleaded petrol with petrol engines, as lead damages
the catalytic converter.
– Do not let the fuel get too low in the tank.
– For engine oil changes, do not replenish with too much engine
oil ⇒ page 212, Topping up engine oil .
– Never tow the vehicle to start it, use jump leads if necessary
⇒ page 256.
If you notice misfiring, uneven running or loss of power when the vehicle is
moving, reduce speed immediately and have the vehicle inspected at the
nearest specialised workshop. In general, the exhaust gas warning lamp
will light up when any of the described symptoms occur ⇒ page 65. If this
happens, unburnt fuel can enter the exhaust system and escape into the en-
vironment. The catalytic converter can also be damaged by overheating.
181
Driving and the environment
WARNING
The catalytic converter reaches very high temperatures! Risk of fire!
● Never park where the catalytic converter could come into contact with
dry grass or flammable materials under the vehicle.
● Do not apply additional underseal or anti-corrosion coatings to the
exhaust pipes, catalytic converter or the heat shields on the exhaust sys-
tem. These materials could catch fire when the vehicle is being driven.
CAUTION
Never run the fuel tank completely dry because the irregularity of the fuel
supply may cause ignition problems. This allows unburnt fuel to enter the
exhaust system, which could cause overheating and damage the catalytic
converter.
For the sake of the environment
Even when the emission control system is working perfectly, there may be a
smell of sulphur from the exhaust gas under some conditions. This depends
on the sulphur content of the fuel used. Quite often the problem can be
solved by changing to another brand of fuel. Diesel engine particulate filter*
The diesel particulate filter eliminates soot produced by
burning diesel.
Fig. 128 Vehicle data
sticker on back cover of
the Maintenance Pro-
gramme
Your vehicle is fitted with a DPF (Diesel particulate filter) if the vehicle data
sticker (back cover of the “Maintenance Programme”) lists the PR code 7GG
or 7MG ⇒ Fig. 128.
The diesel engine particulate filter eliminates most of the soot from the ex-
haust gas system. Under normal driving conditions, the filter cleans itself. If
driving conditions do not allow the filter to clean itself (for example, multi-
ple short trips) the filter will be obstructed by dust and pollen and the diesel
engine particulate filter warning lamp will light up. This does not repre-
sent a fault, it is a warning that indicates that the filter has not been able to
regenerate automatically and that you must carry out a cleaning cycle, as in-
dicated in ⇒ page 70.
