– Press the knob in again to prevent the setting from being changed unintentionally.This button activates or deactivates the daytime running lights function. With
the function activated, when the ignition is switched on the daytime running
lights are turned on automatically.
Note
Please observe any relevant legal requirements which may apply in your
country.Adaptive headlights* (for driving around bends)
When driving around bends, the headlights will light the
most important areas of the road.
The dynamic cornering light gives better illumination of the curve area and
the side of the road when driving around a bend ⇒fig. 91 . The dynamic
cornering light is controlled automatically depending on the speed and the
steering wheel angle.
The dipped beam 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.

188Vehicles with tiptronic gearbox
When the accelerator pedal is pressed right down past the point of resistance
at full throttle, the gearbox will shift down to a lower gear, depending on road
speed and engine speed. The upshift to the next higher gear is delayed until
the engine reaches maximum rpm.
WARNING
P l eas e n o te t ha t i f t h e road s u r fa ce is s l i pp e r y o r w e t , t h e k ick- d ow n fe at u re
could cause the driving wheels to spin, which could result in skidding.Dynamic gear control programme (DCP)
The automatic gearbox is controlled electronically.The vehicle is equipped with an electronically controlled gearbox. The gear
ratios are selected automatically according to preset gearshift programmes.
When you drive at moderate speeds the gearbox will select the most econom-
ical shift programme. It will then change up early and delay the downshifts to
give better fuel economy.
If you drive at higher speeds with heavy acceleration, if you open the throttle
quickly, or if you use the kick-down or the vehicle's maximum speed, the
gearbox will automatically select the sport programme.
The gearbox is self-adapting, and continuously selects the most suitable shift
programme. At the same time, the driver can also make the gearbox switch to
the sport programme by pressing the accelerator quickly. This makes the
gearbox shift down into a lower gear ratio, allowing a more rapid acceleration
(for instance to pass another vehicle), without having to press the accelerator
all the way down into the kick-down position. After the gearbox has shifted
back up it returns to the original programme, depending on your style of
driving. Vehicles with multitronic® gearbox: the gearbox continuously adapts the
gear ratios to gradients. If the brake
pedal is pressed on a downhill gradient
the gearbox automatically shifts to a lower gear ratio. This increases the
engine braking effect.
Vehicles with tiptronic gearbox: in mountainous areas, the gearbox adapts
the gears for uphill and downhill gradients. This helps to avoid constant gear
changes on uphill gradients.

190Back-up programme
A back-up system is in place if a fault should occur in the
control system.The automatic gearbox switches to the back-up programme if a fault should
occur in the control system. This is indicated by a gear pinion symbol which
lights up on the instrument panel display.
It is still possible to move the selector lever to all positions. The manual shift
programme (tiptronic) is not available when the back-up programme is
active.
Vehicles with tiptronic gearbox: when the selector lever is in position D or S
or in the manual shift programme, the gearbox will remain in 3rd gear if 1st,
2nd or 3rd gears were engaged when the fault occurred. The gearbox will
remain in 5th gear if 4th, 5th or 6th gears were engaged. The gearbox will
then engage 3rd gear when you drive away from a standstill or after the
engine is restarted.
It will still be possible to use reverse gear in the normal way. However, the
electronic lock for reverse gear will be switched off.
Caution
Should the gearbox ever switch into the back-up programme, you should take
the vehicle to a technical service or qualified workshop as soon as possible.
Steering wheel with paddle levers
The paddle levers on the steering wheel enable the driver to
manually select pre-programmed ratios or gears.– Briefly pull the left-hand paddle lever to change down to a
lower gear.
– Briefly pull the right-hand paddle lever to change up to a higher gear.The paddle levers are activated when the selector lever is in position D or S,
or the position for the manual shift programme (tiptronic).
The manual shift programme can, of course, still be operated using the
selector lever in the centre console.

Practical TipsIntelligent technologyElectronic Stability Programme (ESP)General notes
The Electronic Stability Programme increases the vehicle's
stability on the road.The ESP is designed to increase the degree of control in situations where the
vehicle 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 Stability
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 vehicle. If the desired course is not being
maintained (for instance, if the vehicle is starting to skid), then the ESP
compensates automatically by braking the appropriate wheel.
The forces acting on the braked wheel bring the vehicle back to a stable
condition. 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 the inside of the bend.
The ESP works in conjunction with the ABS ⇒page 192. If a malfunction
should occur in the ABS, the ESP will also stop working.
Deactivating
The ESP is activated automatically when the engine is started and performs a
self-test routine.

Corrosion
There may be a tendency for corrosion to form on the discs and dirt to build
up on the brake pads if the vehicle is used infrequently or the brakes are not
used very often.
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 at 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
specialised workshop and have the fault repaired. Drive there slowly and
remember that you will have to apply more pressure on the brake pedal and
allow for longer stopping 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 it is
not necessary to brake. This overheats the brakes, resulting in longer stop-
ping distances and greater wear.•Before driving down a long, steep gradient, it is advisable to reduce speed
and change to a lower gear (or move the gear lever to a lower gear position if
your vehicle has automatic transmission). 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 vehicle 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 increases 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 while in neutral, when the engine 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.
