- Depending on the vehicle equipment, the
instrument lighting (for dials and needles)
may be switched on when the ignition is on
and the vehicle's lights are off. The illumi­
nation of the diaLs and needles is automati­
cally reduced as it becomes dark outside
and is eventually switched off altogether.

nition is switched on. In order to avoid possible
damage to the engine, please read the following
notes for the different temperature ranges.
Engine cold
If the LEDs are still in the lower range of the dis­
play, this indicates that the engine has not yet
reached operating temperature. Avoid high en­
gine speeds, full acceleration and heavy engine

loads.

Normal temperature
The LEDs will settle somewhere in the centre of
the display once the engine has reached operat­
ing temperature. If the warning lamp || lights
up in the instrument cluster display, the coolant
temperature is too high

- Additional lights and other accessories in
front of the air inlet reduce the cooling ef­
fect of the radiator. At high outside temper­
atures and high engine loads, there is a risk
of the engine overheating.
- The front spoiler also ensures proper distri­
bution of the cooling air when the vehicle is

moving.
If the spoiler is damaged this can
reduce the cooling effect, which could cause
the engine to overheat. Obtain professional
assistance.
® Note
Applies to: vehicles with diesel engine
These engines are so efficient that they may
not reach their full operating temperature in
very cold weather. This is quite normal and no
cause for concern.
Rev counter

The
rev counter indicates the number of engine
revolutions per minute.
The start of the red zone on the dial indicates the
maximum engine speed which may be used brief­
ly in all gears when the engine is warm and after
it has been run in properly. However, it is advisa­
ble to change up a gear or move the selector lev­
er to D/S (or
lift your
foot
off
the accelerator) be­
fore the needle reaches the red zone. •

The diesel particulate filter requires regenera­

tion.
You can assist the self-cleaning function of
the filter by driving as follows:
Drive at a speed of at least 60 km/h for about
15 minutes in 4th or 5th gear (on vehicles with
manual gearbox), or with the selector lever in po­
sition S (on vehicles with automatic gearbox).
Keep the engine speed at about 2000
rpm.
As a
result of the increase in temperature, the soot in
the filter will be burned off. The indicator lamp
will go out once the cleaning process has been
completed successfully.
If the indicator lamp does not go out, drive to a
qualified workshop without delay and have the
fault rectified.
A WARNING
It is essential that you adjust your speed to
suit the weather,

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
328,
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
lampH
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 •

A WARNING
- Always adapt your driving style to the traffic
conditions.
- Only use the launch control programme
when road and traffic conditions permit,
and make
sure
your manner of driving and
accelerating the vehicle does not inconven­
ience or endanger other road users.
- Please note that the driven wheels may
start to spin when the off-road mode is
switched on, causing the vehicle to Lose

grip,
in particular on slippery or wet roads -
danger of skidding!
- When acceleration has been completed, you
should deactivate the off-road mode again
by briefly pressing the
|flQFF|
button.
© Note
- The gearbox may be hot after you have used
the launch control programme. In this case,
the programme may not be available for
several minutes. The programme will be
available again after
a
cool-down period.
-Accelerating with the launch control pro­
gramme places a heavy load on all parts of
the vehicLe. This can result in increased wear
and tear.

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. •
