WARNING
•
When the engine is running, the vehicle will start to move as soon as a
gear is engaged and the clutch released.
•
Never select the reverse gear when the vehicle is in motion. Risk of acci-
dent.Note
•
Do not rest your hand on the gear le ver when driving. The pressure of your
hand could cause premature wear on the selector forks in the gearbox.
•
When changing gear, you should always depress the clutch fully to avoid
unnecessary wear and damage.
•
Do not hold the car “on the clutch” on hills. This causes premature wear
and damage to the clutch.

Hill stop
– Hold the vehicle, in all cases, using the foot brake to prevent rolling back.
– Do not try to slow the vehicle us ing another forward gear (engine
braking).
Descending gradients
– With the gear engaged, release the brake and accelerate.The steeper the gradient the lower the gear must be for effective engine
braking. For example, if 3rd gear is used on a very steep gradient, the engine
braking is insufficient and vehicle accelerates. So that the engine speed does
not become excessive, the gearbox changes to the next highest gear. Depress
the brake pedal and move the selector lever to the Tiptronic gate to return to
3rd gear.
WARNING
•
The driver should never leave the vehicle while the engine is running or
with any gear selected. If for any reason you must leave the vehicle with the
engine running, apply the handbrake and move the selector lever to posi-
tion P.
•
When the engine is running and the po sitions D, S or R are selected, it
is necessary to hold the vehicle with the foot brake because the vehicle will
creep at a low speed.
•
Never accelerate while changing the po sition of the selector lever (risk
of an accident).
•
The selector lever must never be moved into the positions R or P while
moving (risk of an accident).
•
Before descending a steep gradient, reduce speed and use the Tiptronic
programme to select a lower gear.
•
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 ca use 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.WARNING (continued)

Note•
The steering wheel controls may be us ed in all selector lever positions
while driving.
HandbrakeUsing the handbrake
The handbrake should be applied firmly to prevent the
vehicle from accidentally rolling away.Always apply the handbrake when you leave your vehicle and when
you park. Applying the handbrake
– Pull the handbrake lever up firmly ⇒
fig. 124.
Releasing the handbrake
– Pull the lever up slightly and press the locking knob in the direc- tion of the arrow ⇒fig. 124 and guide the handbrake lever down
fully ⇒ .
Always apply the handbrake firmly; this prevents you driving with the hand-
brake applied ⇒.
The handbrake warning lamp
 lights up when the handbrake is applied
and the ignition switched on. The warning lamp goes out when the hand-
brake is released.
If you drive faster than 6 km/h with the handbrake on, the following
message* will appear in the instrument display: HANDBRAKE ON. Also, an
audible warning is given.
WARNING
•
Never use the handbrake to slow down the vehicle when it is in motion.
The braking distance is considerably longer, as braking is only applied to
the rear wheels. Risk of accident!
•
If it is only partially released this will cause overheating of the rear
brakes, 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/linings.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 foot brake to stop the vehicle.
–Apply the handbrake.
– The first gear should also be selected.
– Switch off the engine and remove the key from the ignition lock.
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 would roll against the kerb if it did
start to roll.•
If the vehicle is facing downhill, turn the front wheels so that they point
towards the kerb.
•
If the vehicle is 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
selecting first 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 unsupervised in the vehicle. They could set the
vehicle in motion, for example, by releasing the handbrake or the gear
lever / selector lever.
•
Depending on weather conditions, it may become extremely hot or cold
inside the vehicle. This can be fatal.
Acoustic parking aid system*Rear parking aid
The parking aid system will use an acoustic signal to warn of
the approach of any object towards the rear of the vehicle.Description
The acoustic parking aid system will measure the distance between the rear
of the vehicle and any possible obstacle using four ultrasonic sensors located
on the rear bumper. The measuring range of the sensors starts at approxi-
mately and depending on the nature of the obstacle at a distance of:•
side of the rear bumper: 0.8 m
•
centre of the rear bumper: 1.3 mWARNING (continued)

Driving
164Activation
The system is activated by engagement of the reverse gear. A brief acoustic
signal confirms the activation and correct function of the system.
Reversing
The distance warning will begin as soon as an obstacle is detected by the
system. The frequency of the bleeps emitted by the system will increase
rapidly as the vehicle approaches the obstacle.
Within a short distance of about 25 cm, a continuous signal sounds (stop
signal). The driver should not reverse any further.
Trailer towing
For vehicles fitted with a tow bar by the manufacturer, the parking aid system
will not be activated by the engagement of the reverse gear when pulling a
trailer, as the trailer's electric connecter will be plugged into the vehicle.
To avoid system malfunctions, when not driving with a trailer, remove the
trailer hitch.
Possible faults
If a continuous bleep sounds for some seconds when the reverse gear is
engaged, this indicates that there is a fault in the parking aid system.
If the fault continues until the ignition is turned off, the acoustic signal
warning of the fault will not be emitted every time the system is reactivated
(by engaging the reverse gear). Thus, the system ready indication will not
sound either. Have the fault repaired by an Authorised Service Centre as soon
as possible.
If there is no ready signal or no acou stic warning signal then the parking aid
loudspeaker is faulty and may not warn of obstacles.
To ensure that the system works properly, the sensors must be kept clean and
free of ice and snow.
WARNING
•
The sensors have blind spots in which obstacles may not be detected.
•
Always look out for small children and animals because the system will
not always detect them. Always pay at tention when reversing to avoid acci-
dents.
•
The parking aid is not a replacement for driver awareness. The driver
must take full responsibility for parking and other manoeuvres.Caution
•
Please note that low obstacles detected by the system may no longer be
registered by the sensors as the car moves closer, so the system will not give
any further warning. Certain kinds of obstacles (such as wire fences, chains,
thin posts or trailer draw bars, high kerbs or painted railings etc) may not
always be detected by the system, so there is a risk of damaging the vehicle
in such cases.
•
Obstacles with uniform edges and bumps may not be detected immedi-
ately by the system due to their geometry. Take special care around this type
of obstacle such as corners, rectangu lar objects, etc.., these can cause
damage to the vehicle.
• Be es pecially ca reful when manoeuvring into a corner between two
perpendicular walls. Survey the approach of the wall to the side of the vehicle
(using the mirrors)
•
The parking aid system does not repl ace use of the mirrors for manoeu-
vres.
•
Distant ultra-sonic sources (hammers, tyres, construction machinery,
other vehicles with PDC) may interfere with the operation of the system.
•
Periodic cleaning of the sensors, take care not to damage or scratch them.
When cleaning with high pressure washers or steam cleaners, the sensors
should be sprayed for only a very short period and from a distance of more
than 10 cm.

Cruise control system (CCS)*Description
The cruise control system is able to maintain the set speed in
the range from approx. 30 km/h to 180 km/h.Once the speed setting has been saved, you may take your foot off the accel-
erator.
WARNING
It could be dangerous to use the cruise control system if it is not possible
to drive at constant speed.•
For safety reasons the cruise control system should not be used in
dense traffic, in sections with bends or where roads conditions are poor
(e.g. aquaplaning, loose chippings, slippery surfaces, snow). Risk of acci-
dent.
•
Always switch off the CCS when you have finished using it. This will
prevent you using it by mistake.
•
It is dangerous to use a set speed whic h 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 gradi-
ents. The vehicle will accelerate under its own weight. Use the foot brake to
slow the vehicle.
Switching the cruise control system on and offSwitching on the system
–Push the switch ⇒fig. 125 to the left to ON.
Switching off the system
– Either push the switch to the right to OFF or turn the ignition
off when the vehicle is stationary.When the speed regulation is on and a speed is programmed, the indicator
 on the instrument panel is lit.
18)
When the speed regulator (CCS) is turned off the indicator
 is turned off, the
speed regulator is completely deactivated if the 1st gear is engaged.*

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 higher than the stored
speed for longer than 5 minutes. The speed will have to be stored again.
Control of the set speed is switched off if you reduce speed by depressing the
brake pedal. You can reactivate the control by pressing once on the upper part
of the rocker switch
RES+ ⇒ page 166, fig. 127 .
WARNING
It is dangerous to use a set speed wh ich is too high for the current road,
traffic or weather conditions. Risk of accident.Switching off the system temporarily*The cruise control system will be switched off in the following situations:•
if the brake pedal is depressed,
•
if the clutch pedal is depressed,
•
if the vehicle is accelerated to over 180 km/h,
•
when the lever is moved in the direction of OFF without fully being
inserted.
To resume the cruise control, release the brake or clutch pedal or reduce the
vehicle speed to less than 180 km/h and press once on the upper part of the
rocker switch RES ⇒fig. 128 .

Tips and MaintenanceIntelligent technologyBrakesBrake servoThe brake servo amplifies 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
as the brake servo does not function.
•
If the brake servo is not functioning, for example if the vehicle is being
towed, you will have to press the brake pedal considerably harder than
normal.
Brake assist system (BAS)*In an emergency, most drivers brake in time, but not with maximum force.
This results in unnecessarily long braking distances. The brake assist system intervenes here, if you press the brake pedal very
quickly, the brake assist system registers an emergency situation. 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 br
ake pedal. The brake assist system
switches off automatically as soon as you release the brake.
WARNING
•
The risk of accident is higher if yo u drive too fast, if you do not keep
your distance from 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.
•
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.

170Anti-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 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 intervened.
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 guarantee 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 214.
•
If the running gear or brakes are mo dified, 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 car 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 should occur in
the ABS, the TCS will also be out of action.
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.
The TCS is switched on automatically when the engine is started. If necessary,
it may be turned on or off pushing the button on the centre console.
When the TCS is off, the warning lamp is lit. The TCS should normally be left
switched on at all times. Only in exceptional circumstances, when 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 loose surfaces
•
When the vehicle is bogged-down, to free it by “rocking.”WARNING (continued)

Te c h n i c a l D a t a
The TCS should be switched on again afterwards as soon as possible.
WARNING
•
It must be remembered that TCS cann
ot defy the laws of physics. This
should be kept in mind, particular ly 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 wh eels and tyres) could affect the effi-
ciency of the ABS and TCS.
Electronic stabilisation program (ESP)*General notes
The electronic stabilisation program increases the vehicle's
stability on the road.The electronic stabilisation program helps to reduce the danger of skidding.
The electronic stabilisation programme (ESP) consists of ABS, EDL and TCS. Electronic Stabilising Program (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 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 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
•
It must be remembered that ESP cann ot 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, 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.Note
To disconnect using the ESP button ⇒page 151.
