Driving
A WARNING
- The driver should never get out of the
vehi
cle when the engine is running and a gear is
engaged.
If you have to leave your vehicle
while the engine is running, you must apply
the parking brake and engage the parking
lock P.
-If the engine is running and a gear is engag
ed (D/S or R) or the vehicle is in "tiptronic"
mode,
you will need to hold the car with the
footbrake. Otherwise, the car will "creep"
forwards as the power transmission is not
fully interrupted even when the engine is
idling.
- The accelerator pedal must on no account
be pressed inadvertently when the vehicle is
stationary. The vehicle could otherwise start
moving immediately (in some cases even if
the parking brake is engaged) and possibly
cause an accident.
- Do not press the accelerator while selecting
a gear with the vehicle stationary and the
engine running, as this could cause an
acci
dent.
- Never move the selector lever to R or P
when driving at normal speeds, as this could
cause an accident.
- Before you drive down a steep gradient, re
duce the speed and use "tiptronic" to select
a low gear.
- Never allow the brake to drag when driving
downhill and do not use the brake pedal too
often
or
for long periods. Constant braking
will cause the brakes to overheat and will
considerably reduce the effectiveness of the
brakes. It will increase the braking distance
and could cause the brake system to
fail.
- To avoid rolling back on gradients always
hold the vehicLe with the footbrake or park
ing brake if you have to stop.
- Never attempt to hold the vehicle with the
clutch when stopping on a gradient. The
clutch is disengaged automatically if it is
overloaded and becomes too hot - accident
risk! If the clutch is overloaded, the indica
tor lamp
0
will light up and a message will
appear
^>page
92.
© CAUTION
- When you have stopped on a gradient, do
not try to stop the vehicle rolling back by ac
celerating when a gear is engaged. This
could cause the automatic gearbox to over
heat and become damaged. Apply the park
ing brake or press the brake pedal in order
to prevent the vehicle from rolling back.
- If you allow the car to roll with the selector
lever in position N with the engine switched
off, the automatic gearbox will be damaged
as it will not be lubricated
^page

Tow-starting / towing
away.
- In certain driving and traffic conditions, for
instance in stop-and-go traffic, if you have
to pull away frequently or if the vehicle
creeps forwards over a long distance, the
gearbox can overheat and become dam
aged.
If the indicator Lamp
[5J
or the warn
ing

Lights up, stop the vehicle at
the first opportunity and let the gearbox
cool down

© Note
For safety reasons the parking brake will only
release automatically if the driver's door is
closed.
Downhill speed control
Applies to: vehicles with automatic gearbox
The downhill speed control function helps the
driver when driving down steep gradients.
Downhill speed control is activated on a downhill
gradient when the selector lever is in D/S and the
driver presses the brake pedal. The gearbox auto
matically selects a suitable gear for the gradient.
The downhill speed control function attempts to
maintain the speed at which the vehicLe was trav
elling when the foot brake was applied (subject
to the laws of physics and technical limitations of
the power train). It may be necessary to adjust
the speed again using the foot brake. The down
hill speed control can change down to 3rd gear
but no further, so it may be necessary to change
to tiptronic mode on very steep gradients. In this
case,
change down manually to 2nd or 1st gear in •

tiptronic mode to use the engine braking effect
and reduce the load on the brakes.
Downhill speed control is deactivated as soon as
the road Levels out again or you press the acceler
ator pedal.
On vehicles with cruise control system*
<^>page
104, downhill speed control is activated
when you set
a
cruising speed.
A WARNING
The downhill speed control function cannot
defy the Laws of physics and may therefore
not be able to maintain a constant speed in
certain circumstances. Always be prepared to
use the brakes!

speed.
The upshift to the next higher gear is de
layed until the engine reaches maximum rpm.
WARNING
Please note that if the road surface is slippery
or wet, the kick-down feature could cause the
driven wheels to
spin,
which could result in
skidding.

Towing a trailer
Towing a trailer
Driving the vehicle with a
trailer or caravan
Technical requirements
The
towing bracket must comply with certain
technical requirements.
Your car is intended mainly for transporting pas
sengers and luggage. However, if suitably equip
ped,
it can also be used to tow a trailer or cara
van.
If the car is supplied with a factory-fitted towing
bracket it will already have the necessary techni
cal modifications and meet the statutory require
ments.
A 13-pin socket is provided to make the electrical
connection between the car and the trailer. If the
trailer you wish to tow has a 7-pin plug, the nec
essary adapter cable can be obtained from a spe
cialist retailer.
If
a
towing bracket is to be fitted after the car is
purchased,
this must be done according to the in
structions of the towing bracket manufacturer
^page
102.
A WARNING
If
a
towing bracket is retrofitted, the installa
tion should be carried out by
a
qualified work
shop.
- In particular in high outside temperatures it
is not possible to drive up long steep gradi
ents without
a
suitable cooling system. The
engine would then overheat.
- Incorrect installation can result in a safety
risk.
Points to check before towing
There are a number of points which need to be
checked before towing a trailer or caravan.
*•
Observe the maximum permitted trailer
weights
^>page
342.
Trailer weights
Never exceed the maximum permitted trailer
weights.
If
you
do not load the trailer up to the maximum
permitted trailer weight, you can then climb cor
respondingly steeper gradients.
The maximum trailer weights listed are only ap
plicable for altitudes up to 1000 m above sea
level.
With increasing altitude the engine power
and therefore the car's climbing ability are im
paired because of the reduced air density, so the
maximum trailer weight has to be reduced ac
cordingly. The weight of the car and trailer must
be reduced by about 10% for every further
1000 m (or part thereof). This figure refers to
the combined weight of the (loaded) vehicle and
(Loaded) trailer.
The figures for the draw bar weight that appear
on the identification plate of the towing bracket
are for certification purposes only. The correct
figures for your specific model, which may be
lower than these figures for the towing bracket,
are given in the registration documents and in
•=>
page 343.
Drive select*
Please note that the
efficiency*
mode is not
available in towing mode.
Exterior lights
Before starting
a
journey, make sure that all the
lights for the trailer are working properly.
Distributing the load
Distribute loads in the trailer so that heavy ob
jects are as near to the axle as possible. Loads
carried in the trailer must be secured to prevent
them slipping. A badly distributed load can also
affect handling. This can activate the trailer sta
bilisation feature and cause the vehicle to reduce
speed.
Where possible, operate the trailer with the max
imum permitted draw bar weight on the ball
joint of the towing bracket, but do not exceed the
specified limit. •

Towing a trailer
Requirements for correct functioning of the
trailer stabilisation system
If these conditions are not met in
full,
the trailer
stabilisation system will only intervene to a
limi
ted extent or not at all
>=>
A-
- The electrical connection between the towing
vehicle and the trailer must be functioning cor
rectly.
- The load on the trailer must be properly se
cured.
- The tyre pressures on both the vehicLe and the
trailer must be adapted to the load that is be
ing carried.
- Where possible, operate the trailer with the
maximum permitted draw bar weight.
- The trailer overrun brake must be set correctly.
This is important to ensure that the trailer can
be braked correctly, to avoid the vehicle and
trailer "jack-knifing" and to prevent excess
braking of the trailer.
- At low outside temperatures, both the towing
vehicle and the trailer should be fitted with
winter tyres.
A WARNING
It is essential that you adjust your speed to
suit the weather, road and traffic conditions.
Do not let the trailer stabilisation system
tempt you into taking any risks when driving -
this can cause accidents.
- The ESC and trailer stabilisation system
can
not defy the Laws of physics. This should be
kept in mind, particularly on slippery and
wet roads and when towing a trailer with a
light Load.
- The trailer stabilisation system is function
al,
regardless of whether the trailer has a
mechanical overrun brake or not.
- The trailer stabilisation system is not always
able to detect swaying of trailers with a
light load and will therefore not intervene.
- A trailer can still "jack-knife" on slippery
roads with little grip, even if the towing ve
hicle is equipped with the trailer stabilisa
tion system.
-Trailers with a high centre of gravity may
even tip over before they start to sway
side
ways.
-If
you
are not towing a trailer,
but
the
trail
er socket is being used (e.g. for an illumina
ted bicycle rack), the trailer stabilisation
system may be activated in extreme driving
conditions.
- Please note the additional information and
warnings
^>page
98, Driving tips.
Driving tips
Driving with a trailer always requires extra care.
Weight distribution
Try to avoid towing a loaded trailer with an unla
den vehicle. If this cannot be avoided, drive extra
slowly to allow for the unbalanced weight distri
bution.
Speed
Normally, you must not exceed 80 km/h when
towing a trailer or caravan. However, if the
trail
er/caravan is equipped with a trailer stabilisation
system,
you can drive at max. 100 km/h. Please
observe any other regulations applicable in the
country in which you are travelling.
The stability of the car and trailer is reduced with
increasing speed. For this reason it is advisable
not to drive at the maximum permissible top
speed in unfavourable
road,
weather or wind
con
ditions. This applies especially on a downhill gra
dient.
You should always reduce speed immediately if
the trailer shows the slightest sign of swaying.
Never try to stop the swaying by accelerating fur
ther.
Always brake in good time. 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 the trailer wheels locking.
Change down in good time before going down a
steep hill so
that
you can use the engine braking
effect to slow down the vehicLe.
Swaying and pitching can be reduced by attach
ing an extra stabiliser to the trailer. It should •
