gine, please read the following notes for the dif­
ferent temperature ranges.
Engine cold
If the LEDs are still in the left-hand range of the
display, this indicates that the engine has not yet
reached operating temperature. Avoid high en­
gine speeds, full acceleration and heavy engine
loads.
Normal temperature
In normal operation the LEDs will settle some­
where in the centre of the dis play once the en­
gine has reached operating temperature. The
LEDs may also extend further into the right-hand
range of the display when the engine is working

play and the warning lamp.
appears in the dis­
play, the coolant temperature is too high
¢page 12.
CD CAUTION
- 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
Diesel 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.

Fuel gauge
The gauge @ only works when the ignition is
switched on. If there is less than 7 litres of fuel in
the tank, the LED at the bottom of the dial will
light up in red and the indicator lamp tD will ap­
pear c:::>page 16. The LED at the bottom of the
dial will flash in red if the fuel level is very low.
The tank capacity of your vehicle is given in the
Technical data section c:::> page 258.
CD CAUTION
Never run the tank completely dry. If there is
an irregular fuel supply, misfiring can occur.
Unburnt fuel can then enter the exhaust sys­
tem. This can lead to overheating and dam­
age to the catalytic converter.
Warning and indicator
lamps
Description
The warning and indicator lamps light up or flash
in the instrument cluster. Their purpose is to in­
dicate functions or faults.
Some of the warning and indicator lamps may be
accompanied by a driver message and a warning
tone. The warning/indicator lamps and driver
messages on the display can be masked by fur­
ther displays. To display a warning or message
again, use the controls on the multi-function
steering wheel to select the display tab for warn­
ing/indicator lamps and messages c:::> page 18.
If several malfunctions have occurred, you can
use the thumbwheel to scroll through them on
the display.
Some of the warning lamps may be displayed in
different colours.

in the engine management system.
Drive slowly to a qualified workshop without de­
lay and have the engine checked.
W Engine management (diesel engine)
Applies to vehicles: with diesel engine
If the indicator lamp II lights up when the igni­
tion is switched on, the glow plugs are preheat­
ing.
If the indicator lamp flashes while the vehicle is
moving, there is a fault in the engine manage­
ment system.
Drive slowly to a qualified workshop without de­
lay and have the fault rectified.
o Emission control system
If the indicator lamp II lights up or flashes, a
fault has occurred which can reduce the quality of
the exhaust gas and damage the catalytic con­
verter.
Drive slowly to a qualified workshop without de­
lay and have the fault rectified.
,. Diesel particulate filter
Applies to vehicles: with diesel engine and diesel particulate
filter
C Particulate filter: fault. See owner's manual
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, or with the selec­
tor lever in position S on vehicles with automatic
"' gearbox. Keep the engine speed at about
� 2000
rpm. As a result of the increase in tempera-
....
ID ture, the soot in the filter will be burned off. The

.... indicator
lamp will go out once the cleaning proc­
ess 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, road, terrain and traffic con­
ditions. The recommended driving speed
must never lead to the driver disregarding the
traffic regulations.
For more information about the diesel partic­
ulate filter, refer to¢ page 220.
!?\ Engine speed governing
Applies to vehicles: with engine speed governing
la Max. engine speed XXXX rpm
The engine speed will automatically be governed
to the speed displayed in the driver information
system. This protects the engine from overheat­
ing.
The rev limiter is deactivated as soon as the en­
gine temperature is no longer within the critical
range and you have taken your foot off the accel­
erator.
If the rev limiter has been activated because of a
fault in the engine management system, the indi­
cator lamp� will also light up. Make sure that
the engine speed does not exceed the speed dis­
played in the driver information system, for ex­
ample when shifting down a gear. Drive to a
qualified workshop without delay and have the
fault rectified.

In some situations (such as when driving on
mountain roads) it can be advantageous to
switch temporarily to the manual shift pro­
gramme so that the gear ratios can be selected
manually to suit the driving conditions
¢page 75.
On level ground it is sufficient to move the selec­
tor lever to P. On a gradient the parking brake
should be applied first and the selector lever
should be moved to P ¢ page 66. This reduces
the load on the locking mechanism and makes it
easier to move the selector lever out of position

gearbox
_&. 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 [!l will light up and a message will
appear¢ page 77.

gearbox
CD 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.
- 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 warning lamp. lights up,
stop the vehicle at the first opportunity and
let the gearbox cool down ¢ page 77.

(1) Note
For safety reasons the parking brake will only
release automatically if the driver's seat belt
is engaged in its buckle.
Downhill speed control
Applies to vehicles: with S tronic 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 0/5 and the
driver presses the brake pedal. The gearbox auto­
matically selects a suitable gear for the gradient.
74 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 80, downhill speed control is activated
when you set a cruising speed.
& 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 circumsta nces. Always be prepared to
use the brakes! -

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 sport mode is switch­
ed 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 sport mode again by
briefly pressing
the I� OFF! button.
ij)) 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.
Back-up programme
Applies to vehicles: with S tronic gearbox
A back-up programme is in place should a fault
occur in the control system.
If all selector lever positions are highlighted in
the infotainment display, a system malfunction
has occurred. In this case, the S tronic gearbox
will switch to a backup programme. The vehicle
can still be driven in the backup programme,
however only at reduced speed and not in all
gears. In certain cases, you may not be able to se­
lect reverse gear.
CD CAUTION
If the gearbox switches to the back-up pro­
gramme, drive to a qualified workshop with­
out delay and have the fault rectified . Automatic

For safety reasons, the cruise control system
must not be used in city traffic, stop-and-go
traffic, on roads with a Lot of bends or in dif­
ficult or slippery driving conditions (such as
ice, fog, Loose grit or gravel, heavy rain, etc.)
- risk of accident!
- When you take a turn-off, drive along a mo-
torway exit Lane or pass through roadwork
sections, please temporarily switch off the
cruise control system.
- Make sure you do not unintentionally rest
your foot on the accelerator -this will over­
ride the cruise control system which, as a re­
sult, will not brake the vehicle.
- The automatic braking function may be de­
activated if a system fault occurs in the
brake system (e.g. if the brakes overheat)
while the cruise control system is activated.
All the other cruise control functions remain
activated as Long as the indicator Lamp ii is
Lit.
CD CAUTION
Before driving down a Long, steep gradient, it
is advisable to reduce speed and move these­
lector Lever to a Lower gear. In this way you
will make use of the engine braking effect and
relieve the Load on the brakes.
w) Note
- Vehicles with manual gearbox: The set
speed cannot be reached if the currently se­
lected gear is too high or too Low or if the
engine would overrev or fail to run smoothly
at the target speed. Make sure to change up
or down a gear in good time.
- The brake Lights come on when the system
brakes the vehicle.

• To increase or reduce the speed gradually, hold
the Lever towards GY0 until you reach the de­
sired cruising speed.
Overruling the set speed
You can use the accelerator pedal to increase
speed in the normal way, for example to overtake
another vehicle. Once you release the accelerator,
the system will revert to the speed you stored ini­
tially.
However, if the vehicle exceeds the programmed
speed significantly for a Long time, the cruise
control system will be deactivated temporarily.
The indicator Lamp ii in the instrument cluster
will go out, but the programmed speed will re­
