the function is enabled, the daytime ru nning lights are switched on automat-
ically when the ignition is switched on.
Note
Please observe any relevant legal requirements which may apply in your
country.Self-directing headlights*
When driving around bends, the headlights will light the
most important areas of the road.
The cornering light gives better illumination of the side of the road when
driving around a bend or taking a turn-off ⇒fig. 89 . The dynamic cornering
light is controlled automatically depending on the speed and the steering
wheel angle.
The headlights are regulated automatically when you drive around a bend,
depending on how far you turn the steering wheel. The two main headlights
move at different angles to avoid that the front of the vehicle is left completely
in the dark.
Note
The system operates from a speed of about 10 km/h.Hazard warning lights
The hazard warning lights are used to draw the attention of
other road users to your vehicle in emergencies.

Practical tipsIntelligent technologyElectronic stabilisation programme (ESP)General notes
The electronic stabilisation programme increases the
vehicle?s stability on the road.The ESP is designed to increase the degree of control in situations where the
car approaches the limits of adhesion, especially when accelerating and
cornering. It reduces the risk of skidding and improves stability in all road
conditions. The system is active across the entire speed range. The anti-lock brake system (ABS), the electronic differential lock (EDL) and
the traction control system (TCS) are all
integrated into the electronic stabili-
sation programme.
How it works
The ESP control unit processes data from the three integrated systems. It also
processes additional inputs provided by other high-precision sensors. These
register the vehicle's rotation about the vertical axis (yaw rate), lateral accel-
eration, brake pressure and steering wheel angle.
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 vehi cle. If the desired course is not being
maintained (for instance, if the car is starting to skid), then the ESP compen-
sates automatically by braking the appropriate wheel.
The forces acting on the braked wheel bring the car back to a stable condi-
tion. If the vehicle over swerves (tendency of the rear to leave the road), the
brakes will act on the front wheel facing the outside of the bend. If the vehicle
under swerves (tendency to leave the bend), the braking force is applied to
the rear wheel facing th e inside of the bend.
The ESP works in conjunction with the ABS ⇒page 176. If a malfunction
should occur in the ABS, the ESP will also be out of action.
Disabling
The ESP is enabled automatically when the engine is started and performs a
self-test routine.

Corrosion
There may be a tendency for dirt to build up on the brake pads and corrosion
to form on the discs if the car is used
infrequently, or if you only drive low
mileages without using the brakes very much.
If the brakes are not used frequently, or if rust has formed on the disks, it is
advisable to clean off the pads and disks by braking firmly a few times from a
moderately high speed ⇒.
Faults in the brake system
If the brake pedal travel should ever increase suddenly, this may mean that
one of the two brake circuits has failed. Drive immediately to the nearest qual-
ified workshop and have the fault rectified. On the way to the dealer, be
prepared to use more pressure on the brake pedal, and allow for longer stop-
ping distances.
Low brake fluid level
Malfunctions can occur in the brake system if the brake fluid level is too low.
The brake fluid level is monitored electronically.
WARNING
When applying the brakes to clean off deposits on the pads and discs,
select a clear, dry road. Be sure not to inconvenience or endanger other
road users. Risk of accident.
Caution
•
Never let the brakes “drag” by leaving your foot on the pedal when you do
not really intend to brake. This overhe ats the brakes, resulting in longer stop-
ping distances and greater wear.
•
Before driving down a long, steep slope, it is advisable to reduce speed
and change into a lower gear. This makes use of engine braking and prolongs
the service life of the brakes. If you still have to use the brakes, it is better to
brake firmly at intervals than to apply the brakes continuously.
Note
If you wish to equip the car with accessories such as a front spoiler or wheel
covers, it is important that the flow of air to the front wheels is not obstructed,
otherwise the brakes can overheat.Brake servo
The brake servo assists the driver when brakingThe brake servo amplifies the pressure you apply to the brake pedal. The
brake servo works only when the engine is running.
WARNING
Ensure the vehicle does not move whil e in neutral, when the motor is
stopped. Failure to do so could result in an accident.
Note
If the brake servo is not working, e.g. because the vehicle has to be towed or
because it is broken, you will have to press the brake pedal considerably
harder to make up for the lack of servo assistance.Power steeringThe power steering assists the driver when turning the
steering wheel (with the engine running).The power steering assists the driver by reducing the force needed to turn the
steering wheel.

Significant tyre pressure lossThe tyre symbol
is displayed and indicates that the tyre pressure for a least
one tyre is insufficient.
- Stop the vehicle.
- Switch the engine off.
- Check the tyre(s).
- Change the wheel if necessary.
Tyre pressure monitoring (RKA+)*
The type pressure monitor display on the instrument panel
indicates that the pressure is too low.The tyre pressure monitoring system makes use of the ABS sensors to
compare the rolling circumference and the frequency characteristics of the wheels. If the rolling cir
cumference or frequency characteristic changes on
one or more wheels, the tyre pressure warning lamp
will light up. The fault
will also be indicated by a warning buzzer. The position of the affected tyre
will also be shown (if only one tyre is affected) on the centre display of the
instrument panel.
The rolling circumference and frequency characteristics can change if:
•
the tyre pressure is too low.
•
the tyre has suffered structural damage.
•
the wheels or the inflation pressures have been changed without initial-
ising the system (see Adjusting the tyre pressure settings).
•
there is a greater load on the wheels of one axle (e.g. if you are carrying
more passengers or luggage).
•
the road surface under the left wheels is different to the road surface
under the right wheels for a long period.
•
when driving with snow chains.
Adjusting the tyre pressure settings (initialising the tyre pressure
monitoring system)
After any incident regarding the wheels of your vehicle, e.g. after modify the
tyre pressure ⇒page 230 or after changing of swapping around wheels ⇒
page 180 - with the vehicle at a standstill and the engine running - press
⇒ fig. 172 . The yellow warning lamp
will light up. Hold the button down
for 2 seconds until the warning lamp goes out and an acoustic warning is
given. You can now release the button.
If the wheels are subjected to extremely stress (e.g. heavy load), the tyre pres-
sure must be increased to the recommended value for the maximum load
(see the adhesive label on the inside of the fuel tank flap) and then initialise
the system.
Tyre pressure warning lamp on
When you switch on the ignition, the tyre pressure warning lamp
will light
up. If the warning lamp flashes and then remains lit after you switch on the
ignition, there is a fault in the system. The instrument panel also display

230TMPS (Tyre Pressure Monitoring Syst em). Please contact the nearest
specialist garage as soon as possible.
The tyre pressure warning lamp
lights up if the tyre pressure on one or
more wheels is significantly lower than the tyre pressure setting which was
confirmed by the driver ⇒.
WARNING
•
If the tyre pressure warning lamp lights up
you must slow down
immediately and avoid any severe braking or steering manoeuvres. Stop
the vehicle as soon as possible and check the tyres and their pressure.
•
The driver is responsible for maintaining correct tyre pressures. There-
fore, the tyre pressure must be regularly checked.
•
Under certain conditions (e.g. drivin g at high speeds, on ice and snow
or on poor road surfaces) the tyre pressure warning lamp
may not light
up immediately or not at all.
•
Please ask your Dealer or specialist garage whether run-flat tyres can
be used on your vehicle. Fitting this type of tyre in an undue manner could
lead to your driving licence being taken away from you. Furthermore, it may
led to damage to the vehicle or, un der certain circumstances, may cause
accidents.
•
If you change normal tyres for run-flat tyres or vice versa, the control
unit must be reprogrammed by the Dealer or a specialist garage.Note
If you did not press the button for the tyre pressure monitoring system to
confirm a new tyre pressure setting after making changes to the tyre pres-
sures or changing one or more wheels, the warning lamp
may light up
although the tyre pressures are correct. In this case, stop the vehicle as soon
as possible and, after examining the tyres, press the button for the tyre pres-
sure monitoring system.
Tyre service life
The service life of tyres is dependent on tyre pressure, driving
style and fitting.

Wear indicators
The original tyres on your vehicle have 1.6 mm high “tread wear indicators”
⇒
page 230, fig. 173 , running across the tread. Depending on the make,
there will be six to eight of them evenly spaced around the tyre. Markings on
the tyre sidewall (for instance the letters “TWI” or other symbols) indicate the
positions of the tread wear indicators. The minimum tread depth required by
law is 1.6 mm (measured in the tread grooves next to the tread wear indica-
tors). Worn tyres must be replaced. Different figures may apply in export
countries ⇒.
Tyre pressure
Under-inflation or over-inflation will reduce the life of the tyres considerably
and also impair the car's handling. The inflation pressures are listed on a
sticker on the inside of the fuel tank flap.
Correct inflation pressures are very important, especially at high speeds. The
pressure should therefore be checked at least once a month and before
starting any long journey.
Tyre pressure monitoring (RKA+)*
Monitoring of the tyre pressures is based on the tyre pressures you have
stored. The tyre pressure monitoring syst em cannot function as intended if
you store tyre pressure settings for a normal load, but then drive with the
vehicle fully laden. The tyre pressure must be adapted to the actual load and
stored accordingly in the tyre pressure monitoring system ⇒page 229.
Driving style
Fast cornering, heavy acceleration and hard braking all increase tyre wear.
Changing wheels around
If the front tyres are worn considerably more than the rear ones it is advisable
to change them around as shown ⇒page 230, fig. 174 . All the tyres will then
last for about the same time. Wheel balance
The wheels on new vehicles are balanced. However, various factors encoun-
tered in normal driving can cause them to become unbalanced, which results
in steering vibration.
Unbalanced wheels should be rebalanced, as they otherwise cause excessive
wear on steering, suspension and tyres. A wheel must also be rebalanced
when a new tyre is fitted.
Incorrect wheel alignment
Incorrect wheel alignment causes excessive tyre wear, impairing the safety of
the vehicle. If tyres show excessive wear, you should have the wheel align-
ment checked by an Authorised Service Centre.
WARNING
There is a serious danger of accidents if a tyre bursts during driving!•
The tyres must be replaced at the latest when the tread is worn down to
the tread wear indicators. Failure to do so could result in an accident. Worn
tyres do not grip well at high speeds on wet roads. There is also a greater
risk of “aquaplaning”
•
At continuously high speeds, a tyre with insufficient pressure flexes
more. This causes it to overheat. This can cause tread separation and tyre
blow-out. Risk of accident. Always observe the recommended tyre pres-
sures.
•
If tyres show excessive wear, you should have the running gear checked
by an Authorised Service Centre.
•
Keep chemicals such as oil, fuel and brake fluid away from tyres.
•
Damaged wheels and tyres must be replaced immediately!For the sake of the environment
Under-inflated tyres will increase fuel consumption.

232Anti-puncture tyres*
Anti-puncture tyres allow you to continue driving even with a
punctured tyre, in the majority of cases.Vehicles equipped with anti-puncture
4) tyres from the factory indi-
cate the loss of tyre pressure on the instrument panel.
Driving with anti-puncture tyres (emergency gear)
– Leave the ESP/TCS (electronic stabilisation programme) switched on, or switch on ⇒page 68.
– Continue driving carefully and slowly (80 km/h maximum).
– Avoid sudden manoeuvres and sharp turns.
– Avoid driving over obstacles (for example kerbs) or potholes.
– Look out for the ESP/TCS intervening often, smoke coming from the tyres or the smell of rubber, the vehicle vibrating or a clat-
tering noise. If any of these occur, stop the vehicle.
The anti-puncture tyres have a tag on the side of the tyre, with the description:
“DSST”, “Eufonia”, “RFT”, “ROF”, “RSC”, “SSR” or “ZP”.
The sides of this type of tyre are reinforced. When the tyres lose air they are
supported on the sides (emergency driving).
The loss of pressure in the tyre is shown on the instrument panel. You can
then drive a maximum of 80 km and if the circumstances are favourable (for
example, low load), even more.
The damaged tyre should be changed as soon as possible. The rim should be
checked in a specialist workshop to detect possible damage and replace it if necessary. We recommend you contact Technical Service. If more than one
tyre is being used under emergency conditions, this reduces the distance
which can be travelled.
Starting driving in emergency conditions
At the moment the loss of tyre pressure is indicated on the instrument panel,
at least one of the tyres is running in an emergency state
⇒.
End of emergency operation
Do not drive on if:
•
smoke is coming from one of the tyres,
•
there is a smell of rubber,
•
the vehicle vibrates,
•
there is a rattling noise.
When is it no longer possible to co ntinue driving even using anti-puncture
tyres?
•
If the Electronic Stabilisation Program (ESP) is out of operation.
•
If the tyre pressure monitoring system is out of operation.
•
If one of the tyres has been severely damaged in an accident, etc. If a tyre
has been badly damaged there is a risk that parts of the tread can be thrown
off and cause damage to the fuel lines, brake pipes or fuel filler.
•
It is also advisable to stop driving if severe vibrations occur, or if the wheel
starts overheating and gives off smoke.
WARNING
When driving in emergency conditions, the driving quality of the vehicle is
considerably impaired.•
The maximum permitted speed of 80 km/h is subject to road and
weather conditions. Please observe legal requirements when doing so.
•
Avoid sharp turns and rapid manoeuvres, and brake earlier than usual.
