WARNING
● Never run the engine in confined spaces, as the exhaust gases are
poisonous.
● Never remove the key from the ignition if the vehicle is in motion.
Otherwise, the steering could suddenly lock, making it impossible to
steer the vehicle: risk of accident!
● Always take the key with you when you leave the vehicle. This is par-
ticularly important if there are children in the vehicle, as they might oth-
erwise be able to start the engine or use power-operated equipment (e.g.
the electric windows), which could cause injuries.
CAUTION
Avoid high engine speeds, full throttle and extreme load conditions until
the engine has reached its normal operating temperature, otherwise this
can damage the engine.
For the sake of the environment
Do not warm up the engine by running it with the car stationary. You should
drive off as soon as you start the engine. This will help avoid unnecessary
exhaust emissions.
Note
● If it is difficult to turn the ignition key to the position 1, turn the steer-
ing wheel to both sides to release the steering lock.
● When starting from cold, the engine may be a little noisy for the first few
seconds until oil pressure has built up in the hydraulic valve lifters. This is
quite normal, and no cause for concern.
● If the vehicle battery is disconnected and reconnected, the key must re-
main in the position 1
for around 5 seconds before starting up.
● Vehicles with automatic gearbox: After switching off the ignition, you
can only remove the ignition key if the selector lever is in position “P” (park-
ing lock). Next, the selector lever is locked. Switching off the engine with the key

– Turn the steering wheel until you hear it engage.
Possible vehicle theft is prevented with the steering lock engaged.
WARNING
● Never switch the engine off until the vehicle is stationary. The brake
servo and power steering functions will not be completely covered under
warranty. More force may also be needed to turn the steering wheel or to
brake. As you cannot steer and brake in the normal manner, there is a
greater risk of accidents and serious injury.
● Never remove the key from the ignition if the vehicle is in motion.
Otherwise, the steering could lock making it impossible to steer the vehi-
cle.
● Always take the ignition key with you whenever you leave the vehicle,
even temporarily. This is particularly important if there are children in
the vehicle, as they might otherwise be able to start the engine or use
power-operated equipment (e.g. the electric windows), which could
cause injuries.

Driving
Always apply the handbrake as far as it will go in order to prevent yourself
from driving with the handbrake applied by mistake ⇒
.
The handbrake warning lamp lights up when the handbrake is applied
and the ignition switched on. The warning lamp turns off when the hand-
brake is released.
If you drive faster than 6 km/h (4 mph) with the handbrake on, the following
message* will appear on the instrument panel display: HANDBRAKE ON. You
will also hear an audible warning.
WARNING
● Never use the handbrake to stop the vehicle when it is in motion. The
braking distance is considerably longer, because braking is only applied
to the rear wheels. Risk of accident!
● 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 also causes premature wear on the
rear brake pads.
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 brake pedal to stop the vehicle. –
Apply the handbrake.
– Select first 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 towards the kerb .
● If the vehicle is parked 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 se-
lecting first gear.
WARNING
● Take measures to reduce the risk of injury when you leave your vehi-
cle 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 example, by releasing the handbrake or the gearbox lever.
● Depending on weather conditions, it may become extremely hot or
cold inside the vehicle. This can be fatal.

Description and operation
The Start-Stop system helps save fuel and reduce CO 2 emissions.
In Start-Stop mode, the engine will automatically switch off when the vehi-
cle stops, when stopping at traffic lights for example. The ignition remains
switched on during the stopping phase. The engine automatically switches
back on when required.
As soon as the ignition is switched on, the Start-Stop function is automati-
cally activated.
Basic requirements for the Start-Stop mode
● The driver door must be closed.
● The driver must have their seat belt fastened.
● The bonnet must be closed.
● The vehicle must have travelled at more than 4 km/h since the last stop.
● The vehicle cannot be towing a trailer.
WARNING
● Never switch the engine off until the vehicle is stationary. The brake
servo and power steering functions will not be completely covered under
warranty. More force may also be needed to turn the steering wheel or to
brake. As you cannot steer and brake in the normal manner, there is a
greater risk of accidents and serious injury.
● Never remove the key from the ignition if the vehicle is in motion.
Otherwise, the steering could lock making it impossible to steer the vehi-
cle.

Note
In vehicles with an automatic gearbox, if the selector lever is placed in posi-
tion D, N or S after engaging reverse gear, the vehicle must be driven at a
speed faster than 10 km/h (5 mph) for the system to return to conditions in
which the engine can be stopped. Manually switching on/off the Start-Stop system
If you do not wish to use the system, you can switch it off
manually.

Downhill speed control*
The downhill speed control function helps the driver when
driving down steep gradients.
Downhill speed control is activated when the selector lever is in D/S and
the driver applies the foot brake. The automatic gearbox automatically en-
gages a lower gear that is suitable for the slope. The downhill speed control
function attempts to maintain the speed at which the vehicle was travelling
when the foot brake was applied (subject to the laws of physics and techni-
cal drive limitations). It may be necessary to adjust the speed again using
the foot brake in certain situations. Given that the downhill speed control
can only change down to 3rd gear, on very steep descents the tiptronic
mode may be required. In this case, manually reduce the tiptronic to 2nd or
1st gear to use the engine brake and reduce the charge on the brakes.
Downhill speed control is deactivated as soon as the road levels out again
or you press the accelerator pedal.
On vehicles with cruise control system* ⇒ page 184, downhill speed con-
trol is activated when you set a cruising speed.
WARNING
The downhill speed control cannot defy the laws of physics. Therefore,
speed cannot be maintained constant in all situations. Always be pre-
pared to use the brakes!
Changing gears in tiptronic mode*
The tiptronic gives the driver the option to change gears
manually.

Driving
– To switch to tiptronic mode, move the selector lever from posi-
tion D/S to the right. As soon as the change is made, the selec-
tor lever will be shown in the position G (i.e. G4 means that 4th
gear is engaged) on the instrument panel display.
– Move the selector lever forwards +
to select a higher gear
⇒ Fig. 123.
– Move the selector lever backwards -
to select a lower gear.
Changing gear manually with the gearshift paddles*
The gearshift paddles can be used when the selector lever is in the
position D/S or G.
– Press the gearshift paddle +
to select a higher gear
⇒ Fig. 124.
– Press the gearshift paddle -
to select a lower gear.
– With the selector lever in position D/S, if no paddle is operated
during a short period of time, the gearbox control system
switches back to automatic mode. To switch to permanent man-
ual gear change using the gearshift paddles, move the selector
lever from position D/S to the right.
When accelerating, the gearbox automatically shifts up into the next gear
shortly before the maximum engine speed is reached.
If you select a lower gear, the automatic gearbox will not shift down until
there is no risk of overrevving the engine.
When the kick-down feature is used, the gearbox shifts down to a lower
gear, depending on road speed and engine speed. Kick-down feature
The kick-down feature allows maximum acceleration to be
reached.
When the accelerator pedal is pressed right down past the point of resist-
ance at full throttle, the gearbox will shift down to a lower gear, depending
on road speed and engine 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 fea-
ture could cause the driving wheels to spin, which could result in skid-
ding.
Launch Control Programme 1)
The Launch control programme enables maximum accelera-
tion.
Important: the engine must have reached operating temperature
and the steering wheel must not be turned.
The engine speed for “launch control” is different in petrol and die-
sel engines. To use the launch-control you must disconnect the an-
ti-slip regulation (ASR) through the Easy Connect system in the
