Driving Tips
Intelligent technology Electronic stability programme (ESP)
General Fig. 137 ESP system: Switch for TCS
The ESP aids you in maintaining control of your vehicle in situations in which the
vehicle is driving at its dynamic limits, such as entering a curve fast. The risk of
skidding is reduced and your car thus offers greater driving stability depending on
the conditions of the road surface. The system operates at all speeds.
The following systems are integrated into the electronic stability programme:
● Electronic Differential Lock (EDL),
● Traction control system (TCS),
● active driver-steering recommendation (DSR),
● Antilock brake system (ABS),
● Brake Assist,
● Uphill Start Assist.
The ESP system cannot be switched off with the 
⇒  fig. 137 button; only the TCS
system is switched off, the warning light  in the instrument cluster lights up. Operating principle
The ESP switches on automatically when the engine is started and then conducts
a self-test. The ESP control unit processes data from the individual systems. It al-
so processes additional measurement data which are supplied by highly sensitive
sensors: the rotational velocity of the vehicle about its vertical axis, the lateral ac-
celeration of the vehicle, the braking pressure and the steering angle.
The direction which the driver wishes to take is determined based on the steering
angle and the speed of the vehicle and is constantly compared with the actual be-
haviour of the vehicle. If differences exist, such as the car beginning to skid, the
ESP will automatically brake the appropriate wheel.
The car is stabilised again by the forces which take effect when the wheel is
braked. Intervention into the brake system takes place primarily on the outer front
wheel of a vehicle which tends to oversteer (tendency for the rear of the vehicle
to break away) while occurs this is on the inner rear wheel of a vehicle which
tends to understeer (tendency to shift out of the curve). This braking control cycle
is accompanied by noises.
During an intervention of the system, the warning light  flashes in the instru-
ment cluster ⇒

 page 27.
The ESP operates in combination with the ABS ⇒ page 157, Antilock brake system
(ABS). If there is a fault in the ABS system, the ESP also does not operate.
The ESP warning light lights up in the instrument cluster when there is a fault on
the ESP  ⇒  page 27. WARNING
It is also not possible for the ESP to overcome the physical limits of the vehi-
cle. Even if a vehicle fitted with ESP you should still always adapt your style of
driving to the condition of the road surface and the traffic situation. This par-
ticularly applies when driving on slippery and wet roads. The increased safety
offered must not tempt you to take greater risks than otherwise - risk of an
accident! £ 153

Operating principle
The TCS switches on automatically when the engine is started and then conducts
a self-test. The system monitors the speeds of the driven wheels with the aid of
the ABS sensors. If the wheels are spinning, the force transmitted to the road sur-
face is automatically adapted by reducing the engine speed. The system operates
at all speeds.
The TCS operates in combination with the ABS ⇒ page 157,
Antilock brake system
(ABS). The TCS will not function if a fault exists in the ABS system.
The TCS warning light lights up in the instrument cluster when there is a fault on
the TCS  ⇒ page 27.
During an intervention of the system, the TCS warning light flashes  in the in-
strument cluster ⇒ page 27.
Switching off
You can also switch off the TCS system by pressing the ⇒ fig. 138 button, or, in ve-
hicles with ESP, by pressing the ⇒ fig. 137 button. The TCS warning light lights up
in the instrument cluster when the TCS is switched off .
The TCS should normally always be switched on. It may be good practice in certain
exceptional cases, such as when you wish to have wheel slip, to switch off the
system.
Examples:
● when driving with snow chains,
● when driving in deep snow or on a loose surface,
● when it is necessary to rock a car free when it has become stuck.
then you should switch on the TCS again.
TCS Off-road
After switching on the Off-road mode ⇒ page 160

, TCS Off-road is activated.
TCS Off-road provides a more effective acceleration of the vehicle on an unfirm
ground, as it allows higher traction between the slipping wheels and the ground.
The system operates when starting off or at low speeds. WARNING
You should always adjust your style of driving to the conditions of the road
surface and the traffic situation. The increased safety offered must not tempt
you to take greater risks than otherwise - risk of an accident! Note
● All four wheels must be fitted with the same tyres in order to achieve prob-
lem-free operation of the TCS. Differing rolling circumferences of the tyres can
lead to an undesirable reduction in the engine output.
● Changes to vehicle (e.g. on engine, on the brakes, on chassis or another combi-
nation of tyres and wheels) can influence the function of the TCS ⇒

cessories, changes and replacement of parts. 
Active driver-steering recommendation (DSR) This function indicates to the driver in critical situations a steering recommenda-
tion in order to stabilise the vehicle. The active driver-steering recommendation is
activated, for example, on the right and left vehicle side when braking sharply on
different road surfaces. WARNING
Even with this function the vehicle cannot steer itself! The driver is further-
more responsible for the steering of the vehicle! 
Brakes What has a negative effect on braking efficiency?
Wear-and-tear
Wear-and-tear to the brake pads is greatly dependent on the operating conditions
of the vehicle and your style of driving. Particularly if you drive a great deal in
towns and over short distances or if you adopt a sporty style of driving, it may be
necessary to have the thickness of the brake pads inspected at a specialist garage
between the service inspections.
Wet roads or road salt
There may be a certain delay before the brakes take full effect under certain con-
ditions such as when driving through water, during heavy rain showers or after
the vehicle has been washed in an automatic vehicle wash, since the brake discs
and brake pads may be moist or even have a coating of ice on them in winter. You
should dry the brakes as soon as possible by applying and releasing the brakes
several times. £ 155
Intelligent technology Using the system Safety Driving Tips General Maintenance Breakdown assistance Technical data

The Brake Assist is able to help you achieve a shorter braking distance in emer-
gency situations by rapidly producing the pressure required in the brake system. It
fully exploits the attributes of the ABS. After you release the brake pedal, the
function of the Brake Assist is automatically switched off and the brakes operate
in the normal way.
The Brake Assist is part of the ESP system. If a fault occurs in the ESP, the Brake
Assist function is also not available. Further information on the ESP
⇒ page 153.WARNING
● The Brake Assist is also not able to overcome the physical limits of your car
in terms of the braking distance required.
● Adapt your speed to the conditions of the road surface and to the traffic
situation.
● The increased safety offered by the Brake Assist must not tempt you to
take a greater safety risk than otherwise. 
Uphill Start Assist The uphill start assist makes it easier to start off on steep hills. The system assists
a start off by holding the brake pressure produced by the brake pedal actuation
for approx. 2 seconds after releasing the brake pedal. The driver can therefore
move his foot from the brake pedal to the accelerator pedal and start off on the
slope, without having to actuate the handbrake. The brake pressure drops gradu-
ally the more you operate the accelerator pedal. If the vehicle does not start off
within 2 seconds, it starts to roll back.
The uphill start assist is active as of a 3 % slope, if the driver door is closed. It is
always active on slopes when in forward or reverse start off. When driving down-
hill, it is inactive. 
Electromechanical power steering The power steering enables you to steer the vehicle with less physical force.
With the electromechanical power steering, the steering assist is automatically
adapted to the speed and to the steering angle.
It is still possible to fully steer the vehicle if the power steering fails or if the en-
gine is not running (vehicle being towed in). The only difference is that greater
physical effort is required. If there is a fault in the power steering, the warning light
 or  lights up in the
instrument cluster ⇒
 page 25. WARNING
Contact your specialist garage if the power steering is defective. 
Tyre pressure monitoring system Fig. 139 Button for setting the tyre in-
flation pressure control value
The tyre pressure monitoring system compares with the aid of the ABS sensors
the speed and also the rolling circumference of the individual wheels. If the rolling
circumference of a wheel is changed, the warning light
 in the instrument clus-
ter ⇒ page 28 and an acoustic signal sounds.
The rolling circumference of the tyre can change if:
● the tyre inflation pressure is too low,
● the structure of the tyre is damaged,
● the vehicle is loaded on one side,
● the wheels of an axle are loaded heavily (e.g. when towing a trailer or when
driving uphill or downhill),
● snow chains are mounted,
● the temporary spare wheel is mounted,
● one wheel per axle was changed. £158
