Driving
●
If the handbrake is only partially released,
this will cause the rear brakes to overheat,
which can impair the function of the brake
system and could lead to an accident. This al-
so causes premature wear on the rear brake
pads. CAUTION
Always apply the handbrake before you leave
the vehicle. Put it in 1st gear as well. Parking
The handbrake should always be firmly ap-
plied when the vehicle is parked.
Always note the following points when park-
ing the vehicle:
– Use the brake pedal to stop the vehicle.
– Apply the handbrake.
– Put it in 1st gear.
– Switch the engine off and remove the key
from the ignition. Turn the steering wheel
slightly to engage the steering lock.
– Always take you 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 to-
wards the kerb .
● If the vehicle is parked facing uphill, turn
the fr ont
wheels so that they point away from
the kerb
.
● Secure the vehicle as usual by applying the
handbrake firmly and putting it in 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 vehicle
occupants.
● Never leave children alone in the vehicle.
They could set the vehicle in motion, for ex-
ample, by releasing the handbrake or the
gearbox lever. ●
Depending on weather conditions, it may
become extremely hot or cold inside the vehi-
cle. This can be fatal. Hill driving assistant*
This function is only included in vehicles with
ESC.
The hill driving assistant helps the driver to
move off and upward on a hill without rolling
backward.
The system maintains brake pressure for ap-
proximately 2 seconds after the driver takes
his foot off the brake pedal to prevent the ve-
hicle from rolling backward when starting off.
During these 2 seconds, the driver has
enough time to release the clutch pedal and
accelerate without the vehicle moving and
without having to use the handbrake, making
starting off easier, more comfortable and saf-
er.
These are the basic operation conditions:
● being on a ramp or hill/slope,
● closed doors,
● vehicle completely stationary,
● engine running and foot on the brake,
● besides having a gear engaged or being in
neutral for manual gear change and with the
selector lever at position S,
D
or R for an au-
tomatic gearbox. »

Stopping briefly – If stopping for a short time, keep the vehi-
cle stationary by pressing the foot brake
hard to prevent the vehicle moving back-
wards on a slope or “creeping” forwards,
e.g. at traffic lights. The selector lever does
not need to be put into the positions P or N
f or thi
s.
– Do not press the accelerator.
Parking
– Press and hold the brake pedal until the ve-
hicle comes to a standstill ››› .
– Apply the handbrake.
– By pressing the lock button down, move
the selector lever to P
and release the lock
b
utton.
Driving up and down hills
– Press the selector lever from position “D”
to the right into the tiptronic selector gate. –
Lightly press the selector lever back to
change down.
Holding the car on a hill – The brake must be always pressed down to
prevent the vehicle from “rolling back-
wards” ››› . Do not try to prevent the vehi-
cle from “rolling backwards” by increasing
the engine speed while a range of gears is
selected.
Starting the vehicle up hills
– Apply the handbrake.
– With a selected gear, accelerate slowly and
at the same time, release the handbrake.
The steeper the slope, the lower the needed
gear. This increases the braking effect of the
engine. For example, when driving down a
very steep slope in third gear. If the engine
brake effect is not enough, the vehicle will
speed up. The automatic gearbox automati-
cally changes up to prevent the engine over-
revving. Use the foot brake to reduce speed
and change into 3rd gear using Tiptronic*

and 120 km/h (75 mph) your vehicle will use
about 12% more fuel as a result of the extra
wind resistance caused by the roof rack even
when it is not in use.
Save electricity
The engine activates the alternator, which
produces electricity. With the need for elec-
tricity, fuel consumption is also increased.
Because of this, always turn off electrical de-
vices when you do not need them. Examples
of devices that use a lot of electricity are: the
fan at high speeds, the rear window heating
or the seat heaters*. Note
● If you vehicle has Start-Stop, it is not rec-
ommended t o sw
itch this function off.
● It is recommended to close the windows
when driving at more than 60 km/h
● Do not drive with your foot resting on the
clutch pedal,, as the pressure can make the
pl
ate spin, more fuel will be used and it can
burn the clutch plate lining, causing a serious
fault.
● Do not hold the vehicle on a hill with the
clutch, use the foot brake or hand brake, us-
ing the latter to start. The fuel consumption
will be lower and you will prevent the clutch
plate from being damaged.
● On descents, use the engine brake, chang-
ing to the gear that is more suitable for the slope. Fuel consumption will be “zero” and
the brakes will not suffer.
Driver assistance systems
Braking and stability systems Electronic Stability Control (ESC)* Fig. 131
Detailed view of the centre console:
ESC switch. This Electronic Stability System reduces the
risk of skidding and improves the vehicle's
stability and ability to hold the road.
Electronic Stability Control (ESC) includes the
electronic differential lock (EDL), the traction
control system (TCS), the brake assist system
(BAS) and the trailer stabilisation programme
(TSP). The ESC works together with the ABS.
Both control lamps will light up if the ESC or
ABS systems are faulty.
The ESC system is started automatically
when the engine is started.
134
Driver assistance systems
The ESC system is always active and cannot
be switched off. The ESC switch only switches
the ASR off.
The ASR can be deactivated when wheel spin
is desirable.
For example:
● When driving with snow chains.
● When driving in deep snow or on loose sur-
faces.
● When the vehicle is stuck, to rock it back-
wards and forwards.
Press the button to switch the ASR back on
when you no longer need wheel spin.
Electronic Stability Control (ESC)*
The ESC reduces the risk of skidding by brak-
ing the wheels individually.
The system uses the steering wheel angle
and road speed to calculate the changes of
direction desired by the driver, and constant-
ly compares them with the actual behaviour
of the vehicle. When irregularities occur, for
example, if the vehicle begins to skid, the
ESC brakes the appropriate wheel automati-
cally.
The forces acting on the braked wheel bring
the vehicle back to a stable condition. If the
vehicle tends to oversteer (the rear end
slides out), the system will act on the front
wheel on the outside of the turn. Steering manoeuvre recommendations
This is a complementary safety function in-
cluded in the ESC. This function aids the driv-
er to better stabilize the vehicle in a critical
situation. For example, in case of sudden
braking on a surface with varied adherence,
the vehicle will tend to destabilise its trajec-
tory to the right or to the left. In this case, the
ESC recognises the situation and assists the
driver with a counter steering manoeuvre
from the power steering.
This function simply provides the driver with
a recommended manoeuvre in critical situa-
tions.
The vehicle does not steer itself with this
function, the driver has full control of the ve-
hicle at all times.
WARNING
● Remember that not even the ESC can 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 situa-
tion. The greater safety provided by the ESC
should not encourage you to run any risks. CAUTION
● To ensure that the ESC works 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 en-
gine power when this is not desired.
● Any modifications made to the vehicle (for
example, to the engine, brake system, run-
ning gear or to the combination of wheels
and tyres) may affect the operation of the
ABS, EDL, ESC and ASR. Electronic differential lock (EDL)*
EDL helps the vehicle to start moving, accel-
erate and climb a gradient in slippery condi-
tions where this may otherwise be difficult or
even impossible.
It uses the ABS sensors to monitor the speed
of the driven wheels. In case of an EDL fault,
the warning light for ABS lights up
››› page 41 .
At s
peeds of up to approximately 80 km/h
(50 mph), it is able to balance out differences
in the speed of the driven wheels of approxi-
mately 100 rpm/min caused by a partially
slippery road surface. It does this by braking
the wheel which has lost traction and distrib-
uting 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 au-
tomatically 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 accel-
erator 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 in-
to taking any risks when driving, this can
cause accidents. CAUTION
Modifications to the vehicle (e.g. to the en-
gine, the brake system, running gear or any
components affecting the wheels and tyres)
could affect the efficiency of the EDL
››› page 147. Hydraulic Brake Assist (HBA)*
The function (Hydraulic Brake Assist HBA) is
only included in vehicles with ESC.
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 emer-
gency. It very quickly builds up the full brake
pressure so that the ABS can be activated
more quickly and efficiently, thus reducing
braking distance.
Do not reduce the pressure on the brake ped-
al, since the brake assist system switches off
automatically as soon as you release the
brake.
Emergency braking warning
If the vehicle is braked suddenly and continu-
ously at a speed of more than 80 km/h, the
brake light flashes several times per second
to warn vehicles driving behind. If you contin-
ue 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 from
the vehicle in front, and when the road sur-
face is slippery or wet. The increased acci-
dent risk cannot be reduced by the brake as-
sist 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.
Anti-lock brake system (ABS)
The anti-lock brake (ABS) system prevents
the wheels from locking during braking and
is an important part of the vehicle's active
safety system.
How the ABS works
If one of the wheels turns too slowly in rela-
tion to the vehicle's speed, and is close to
locking, the system will reduce the braking
pressure to 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 regu-
late 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.
Br ak
ing distance could even be further if you
136
Driver assistance systems
brake on gravel or on fresh snow on 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 fea-
tures tempt you into taking any risks when
driving.
● The effectiveness of ABS is also determined
by the tyres fitted ››› page 175.
● If the ru
nning gear or brake system is modi-
fied, the effectiveness of the ABS could be se-
verely limited. Drive wheel traction control system
(ASR)
The traction control system prevents the driv-
en wheels from spinning when the vehicle is
accelerating.
Description and operation of the traction
control system during acceleration (ASR
On front-wheel drive vehicles, the ASR sys-
tem intervenes, reducing engine power and
preventing the driven wheels from slipping
during acceleration. The system works in the entire speed range in conjunction with ABS.
If a failure occurs in the ABS, the ASR will al-
so stop working.
TCS helps the car to start moving, accelerate
and climb a gradient in slippery conditions
where this may otherwise be difficult or even
impossible.
The ASR automatically switches on when the
engine is started. If necessary, it may be
turned on or off by briefly pushing the button
on the centre console.
When the ASR is switched off, the
OFF warning lamp will light up. The ASR should
normally be left on. Only in exceptional cir-
cumstances, when slipping of the wheels is
desired, should it be disconnected.
●
With compact temporary spare wheel.
● When using the snow chains.
● When driving in deep snow or on soft ter-
rain.
● When the vehicle is bogged-down, to free it
by “rocking.”
The ASR should be switched on again as
soon as possible. WARNING
● Remember that not even the ASR can 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 situa-
tion. The greater safety provided by the ASR
should not encourage you to run any risks. CAUTION
● To ensure that the ASR works correctly,
identical tyres should be fitted on all four
wheels. Any differences in the rolling radius
of the tyres can cause the system to reduce
engine power when this is not desired.
● Any modifications made to the vehicle (for
example, to the engine, brake system, run-
ning gear or to the combination of wheels
and tyres) may affect the operation of the
ABS and ASR. XDS*
When taking a curve, the driveshaft differen-
tial mechanism allows the outer wheel to turn
at a higher speed than the inner wheel. In
this way, the wheel that is turning faster (out-
er 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.

Tyre pressure
Set tyre pressure to the maximum permissi-
ble pressure shown on the sticker on the in-
side of the fuel tank flap. Set the tyre pres-
sure of the trailer tyres in accordance with the
trailer manufacturer's recommendations.
Exterior mirrors
Check whether you can see enough of the
road behind the trailer with the standard rear
vision mirrors. If this is not the case, you
should have additional exterior mirrors fitted.
Both exterior mirrors should be mounted on
hinged extension brackets. Adjust the mirrors
to give sufficient vision to the rear. WARNING
Never transport people in a trailer. This could
result in fatal accidents. Note
● Towing a trailer places additional demands
on the vehicle. We recommend additional
services between the normal inspection inter-
vals if the vehicle is used frequently for tow-
ing a trailer.
● Find out whether special regulations apply
to towing a trailer in your country. Ball coupling of towing bracket*
Depending on the model version, the spheri-
cal head on the trailer hook may be stored in
the tool box.
The ball coupling is provided with instruc-
tions on fitting and removing the ball cou-
pling of the towing bracket.
WARNING
The towing bracket ball coupling must be
stored securely in the luggage compartment
to prevent them being flung through the vehi-
cle and causing injury. Note
● By law, the ball coupling must be removed
if a trailer is not being towed if it obscures
the number plate. Driving tips
Driving with a trailer always requires extra
care.
Weight distribution
The weight distribution of a loaded trailer
with an unladen vehicle is very unfavourable.
However, if this cannot be avoided, drive ex-
tra slowly to allow for the unbalanced weight
distribution.Speed
The stability of the vehicle and trailer is re-
duced with increasing speed. For this reason,
it is advisable not to drive at the maximum
permissible speed in an unfavourable road,
weather or wind conditions. This applies es-
pecially when driving downhill.
You should always reduce speed immediately
if the trailer shows the slightest sign of
snak-
ing . Never try to stop the “snaking” by in-
c r
easing speed.
Always brake in due course. If the trailer has
an
overrun brake, apply the brakes gently at
first and then, firmly. This will prevent the
jerking that can be caused by locking of trail-
er wheels. Select a low gear in due course
before going down a steep downhill. This en-
ables you to use the engine braking to slow
down the vehicle.
Reheating
At very high temperatures and during pro-
longed slopes, driving in a low gear and high
engine speed, always monitor the coolant
temperature gauge ››› page 31.
Electronic Stability Control*
The ESC* system helps to stabilise the trailer
in case of skidding or rocking.
