Driving
174•If you must stop on a hill, always hold the vehicle using the footbrake
to avoid rolling back.•The footbrake must not be held for a long period of time, not even
lightly; continuous braking will cause overheating of the brakes and a
reduction or even a loss of braking power and a significant increase in
braking distances.•Never allow the vehicle to coast down a gradient with the selector lever
in positions N or D, even when the engine is not running. For descents, the
use of the tiptronic programme is recommended to keep the speed
reduced.Caution
•Never use the automatic gearbox to hold the vehicle stationary on a hill,
even for short periods, as this may overheat the gearbox and cause damage.
Apply the handbrake or depress the foot brake to hold the vehicle in position.•If the vehicle is allowed to roll with the engine stopped but the selector in
position N then the gearbox may be damaged because it will not be
lubricated.

Changing gear with the steering wheel levers
– Press the right paddle lever ( +OFF) towards the steering
wheel to change up ⇒ page 174, fig. 128.
– Press the left paddle towards the steering wheel to change
down ⇒page 174, fig. 128 .Using the paddle levers on the steering wheel, you can access manual driving
mode regardless of the pre-selected driving mode.
General information about driving in tiptronic mode
When accelerating, the automatic gearbox / DSG automatic gearbox goes
into a higher gear a little before the engine reaches its maximum permitted
revolutions.
If a lower gear is selected, the automatic gearbox / DSG automatic gearbox
will only change down when the engine cannot go over its maximum
permitted revolutions.
If tiptronic is selected whilst the vehicle is in motion and the automatic
gearbox / DSG automatic gearbox is in third gear and selector lever position
D, tiptronic mode will then also be in third gear. Changing gears in the normal or sport programme using the steering wheel
paddle levers
If the paddle levers ⇒
page 174, fig. 128 are used in the normal or sport
programme, the system switches temporarily to tiptronic mode. To exit
tiptronic mode again, press the right paddle lever towards the steering
wheel for approximately one second. You will also leave tiptronic mode if the
paddle levers are not moved for a certain time.
Note
•The gearbox controls on the steering wheel can operate with the selector
lever in any position and with the vehicle in motion.Kickdown feature
This feature allows maximum acceleration.If you press the accelerator down thoroughly, the gearbox automatically
changes down, depending on speed and e ngine speed, into a lower gear to
take full advantage of give the vehicle maximum acceleration.
The gearbox does not change gear until the engine reaches the maximum
determined engine speed for the gear.
WARNING
You could lose control of the vehicle if you accelerate on slippery road
surfaces. Risk of serious injury.•Be particularly careful when using the kickdown features on slippery
road surfaces. With a fast acceleration, the vehicle could lose traction and
skid.•You should use the kickdown feature only when traffic and weather
conditions allow it to be used safely.

– Apply the handbrake.
– The 1st gear should also be selected.
– Switch the engine off and remove the key from the ignition. Turn
the steering wheel slightly to engage the steering lock.
– Always take you car 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
engaging 1st gear.WARNING
•Take measures to reduce the risk of injury when you leave your vehicle
unattended.•Never park where the hot exhaust system could ignite inflammable
materials, such as dry grass, low bushes, spilt fuel etc.•Never allow vehicle occupants to remain in the vehicle when it is
locked. They would be unable to open the vehicle from the inside, and
could become trapped in the vehicle in an emergency. In the event of an
emergency, locked doors will delay assistance to occupants.•Never leave children alone in the vehicle. They could set the vehicle in
motion, for example, by releasing the handbrake or the gear lever.
•Depending on weather conditions, it may become extremely hot or cold
inside the vehicle. This can be fatal.
Hill-start aid*
This function is only included in vehicles with ESP.This device helps when starting uphill.
These are the basic operation conditions: doors closed, brake pedal pressed
down and vehicle in neutral. The system gets activated on engaging gear.
This system also works when reversing uphill.
After removing your foot from the brake pedal, the braking force is maintained
for a few seconds to prevent the vehicle from moving backward when putting
into gear. This short space of time is enough to start the vehicle with ease.
This system also works when reversing uphill.
WARNING
•If you do not start the vehicle immediately after taking your foot off the
brake pedal, the vehicle may start to roll back under certain conditions.
Depress the brake pedal or use the hand brake immediately.•If the engine stalls, depress the brake pedal or use the hand brake
immediately.•When following a line of traffic uphill, if you want to prevent the vehicle
from rolling back accidentally when starting off, hold the brake pedal down
for a few seconds before starting off.WARNING (continued)

Practical TipsIntelligent technologyBrakesBrake servoThe 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 considerably
when the brake servo is not active.•If the brake servo is not working, for example when the vehicle is being
towed, you will have to press the brake pedal considerably harder than
normal.
Hydraulic Brake Assist (HBA)*
The Hydraulic Brake Assist function (HBA) is only included in
vehicles with ESP.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.
Emergency braking warning
If the vehicle is braked suddenly and continuously at a speed of more than 80
km/h, the brake light flashes several times per second to warn vehicles
driving behind. If you continue braking, the hazard warning lights will come
on automatically when the vehicle comes to a standstill. They switch off auto-
matically when the vehicle starts to move again.
WARNING
•The risk of accident is higher if you drive too fast, if you do not keep
your distance to the vehicle in front, and when the road surface is slippery
or wet. The increased accident risk cannot be reduced by the brake assist
system.

186•The brake assist system cannot defy the laws of physics. Slippery and
wet roads are dangerous even with the brake assist system! Therefore, it is
essential that you adjust your speed to suit the road and traffic conditions.
Do not let the extra safety features tempt you into taking any risks when
driving.
Anti-lock brake system and traction control
M-ABS (ABS and TCS)Anti-lock brake system (ABS)
The anti-lock brake system prevents the wheels locking
during braking.The anti-lock brake system (ABS) is an important part of the vehicle’s active
safety system.
How the ABS works
If one of the wheels is turns too slowly in relation to the road speed, and is
close to locking, the system will reduce the braking pressure for this wheel.
The driver is made aware of this control process by a pulsating of the brake
pedal and audible noise. This is a deliberate warning to the driver that one or
more of the wheels is tending to lock and the ABS control function has inter-
vened. In this situation it is important to keep the brake pedal fully depressed
so the ABS can regulate the brake application. Do not “pump”.
If you brake hard on a slippery road surface, the best possible control is
retained as the wheels do not lock. However, ABS will not necessarily gu
arantee shorter braking distances in all
conditions. The braking distance could even be longer if you brake on gravel
or on fresh snow covering a slippery surface.
WARNING
•The anti-lock brake system cannot defy the laws of physics. Slippery
and wet roads are dangerous even with ABS! If you notice that the ABS is
working (to counteract locked wheels under braking), you should reduce
speed immediately to suit the road and traffic conditions. Do not let the
extra safety features tempt you into taking any risks when driving.•The effectiveness of ABS is also determined by the tyres fitted
⇒ page 237.•If the running gear or brakes are modified, the effectiveness of the ABS
could be severely limited.
Traction control system (TCS)
The traction control system prevents the drive wheels from
spinning when the vehicle is accelerating.Description and operation of the traction control system during acceleration
(TCS)
TCS reduces engine power to help prevent the drive wheels of front-wheel
drive vehicles losing traction during acceleration. The system works in the
entire speed range in conjunction with ABS. If a malfunction occurs in the
ABS, the TCS will also be inoperative.
TCS helps the vehicle to start moving, accelerate and climb a gradient in slip-
pery conditions where this may otherwise be difficult or even impossible.

When the TCS is off, the warning lamp is lit. The TCS should normally
be left on. Only in exceptional circumstances, when the slipping of the wheels
is required, should it be disconnected, for example
•With compact temporary spare wheel.•When using the snow chains.•When driving in deep snow or on soft terrain.•When the vehicle is bogged-down, to free it by rocking.
The TCS should be switched on again as soon as possible.WARNING
•It must be remembered that TCS cannot 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. Do not let the extra safety afforded by TCS tempt you
into taking any risks when driving, this can cause accidents.Caution
•In order to ensure that TCS function 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.•Modifications to the vehicle (e.g. to the engine, the brake system, running
gear or any components affecting the wheels and tyres) could affect the effi-
ciency of the ABS and TCS.
XDS*
Driveshaft differentialWhen taking a bend, the driveshaft differential mechanism allows the outer
wheel to turn at a higher speed than the inner wheel. In this way, the wheel
that is turning faster (outer wheel) receives less drive torque than the inner
wheel. This may mean that in certain situations the torque delivered to the
inner wheel is too high, causing the wheels to spin. On the other hand, the
outer wheel is receiving a lower drive torque than it could transmit. This
causes an overall loss of lateral grip on the front axle, resulting in understeer
or “lengthening” of the trajectory.
By using the ESP sensors and signals, the XDS system is able to detect and
correct this effect.
Through the ESP, the XDS brakes the inner wheel, thereby counteracting the
excess drive torque in this wheel. This means that the driver’s desired trajec-
tory is much more precise,
The XDS system operates in combination with the ESP and is always active,
even when the traction control, TCS, is disconnected.Electronic Stability Programme (ESP)*General notes
The Electronic Stability Programme increases the vehicle’s
stability on the road.The Electronic Stability Programme helps reduce the danger of skidding.
The Electronic Stability Programme (ESP) consists of ABS, EDL, TCS and
Steering manoeuvre recommendations.

188Electronic Stability Programme (ESP)*
ESP reduces the danger 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. 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 tends to oversteer, the system will act on the front
wheel on the outside of the turn.
Steering manoeuvre recommendations
This is a complementary safety function included in the ESP This function aids
the driver to better stabilize the vehicle in a critical situation. For example, in
case of sudden braking surface with varied adherence, the vehicle will tend
to destabilise its trajectory to the right or to the left. In this case the ESP
recognizes the situation and helps the driver with a counter steering
manoeuvre from the power steering.
This function simply provides the driver with a recommended manoeuvre in
critical situations.
The vehicle does not steer itself with this function, the driver has full control
of the vehicle at all times.
WARNING
•It must be remembered that ESP cannot 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. Do not let the extra safety afforded by ESP tempt you
into taking any risks when driving, as this can cause accidents.
Caution
•In order to ensure that ESP functions 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.•Modifications to the vehicle (e.g. to the engine, the brake system, running
gear or any components affecting the wheels and tyres) could affect the effi-
ciency of the ABS, EDL, ESP and TCS.Anti-lock brake system (ABS)The anti-lock brake system prevents the wheels locking during braking
⇒ page 186.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 slip-
pery conditions where this may otherwise be difficult or even impossible.
The system will control the revolutions of the drive wheels using the ABS
sensors (in case of an EDL fault the warning lamp for ABS lights up)
⇒ page 84.
At speeds of up to approximately 80 km/h, it is able to balance out differ-
ences 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 continue to
function normally without EDL. For this reason, the driver is not informed that
the EDL has been switched off.
The EDL will switch on again automatically when the brake has cooled down.
WARNING
•When accelerating on a slippery surface, for example on ice and snow,
press the accelerator carefully. Despite EDL, the driven wheels may start to
spin. This could impair the vehicle’s stability.•Always adapt your driving style to suit road conditions and the traffic
situation. Do not let the extra safety afforded by EDL tempt you into taking
any risks when driving, this can cause accidents.Caution

gear or any components affecting the wheels and tyres) could affect the effi-
ciency of the EDL ⇒page 212.The traction control system (TCS)The traction control system prevents the drive wheels from spinning when the

All-wheel drive*
On all-wheel drive models, the engine power is distributed to
all four wheelsGeneral notes
The all-wheel drive system operates completely automatically. The propul-
sion force is distributed among the four wheels and adapted to the driving
style and the road conditions.
The all-wheel drive is specially designed to complement the superior engine
power. This combination gives the vehicle exceptional handling and perform-
ance capabilities, both on normal roads and in more difficult conditions, such
as snow and ice.
Winter tyres
Thanks to its all-wheel drive, your vehicle will have plenty of traction in winter
conditions, even with the standard tyres. Nevertheless, we still recommend
that winter tyres or all-season tyres should be fitted on all four wheels when
winter road conditions are expected, mainly because this will give a better
braking response.
Snow chains
On roads where snow chains are mandatory, this also applies to cars with all-
wheel drive.
Changing tyres
On vehicles with all-wheel drive, all four tyres must have the same rolling
circumference ⇒page 242.
WARNING
•Even with all-wheel drive, you should always adjust your speed to suit
the conditions. Do not let the extra safety features tempt you into taking
any risks when driving. Failure to do so could result in an accident.
