During automatic
wipe
The air conditioner comes on for
approximately 30 seconds in air
recirculation mode to prevent the
smell of the windscreen washer
fluid entering the inside the vehi-
cle.
For the interval wipe
Intervals between wipes depend
on the vehicle's speed. The high-
er the vehicle speed the shorter
the intervals. Heated windscreen washer jets
The heating only thaws the frozen jets, it
does not thaw the water in the washer hoses.
The heated windscreen washer jets automati-
cally adjust the heat depending on the ambi-
ent temperature, when the ignition is switch-
ed on.
Headlight wash/wipe system
The headlight washers/wipers clean the
headlight lenses.
After the ignition is switched on, the first and
every fifth time the windscreen washer is
switched on, the headlights are also washed. Therefore, the windscreen wiper lever should
be pulled towards the steering wheel when
the dipped beam or main beam are on. Any
incrusted dirt (such as insects) should be
cleaned regularly (e.g. when refuelling).
To ensure the headlight washers work cor-
rectly in winter, any snow which has got into
the bumper jet supports should be cleaned
away. If necessary, remove snow with an anti-
icing spray.
Note
The wiper will try to wipe away any obstacles
that are on the windscreen. The wiper will
stop moving if the obstacle blocks its path.
Remove the obstacle and switch the wiper
back on again. Rain sensor*

Convex or wide-angle* exterior mirrors give a
larger field of vision. However, they make ob-
jects look smaller and further away than they
really are. If you use these mirrors to esti-
mate the distance to vehicles behind you
when changing lane, you could misjudge the
distance. Risk of accident! CAUTION
● If one of the mirror housings is knocked out
of position (e.g. when parking), the mirrors
must first be fully retracted with the electric
control. Do not readjust the mirror housing by
hand, as this will interfere with the mirror ad-
juster function.

People who, because of medications, paraly-
sis or chronic diseases (e.g. diabetes) cannot
perceive pain or temperature, or have a limi-
ted perception thereof, may suffer burns to
the back, buttocks or legs when using seat
heating, an occurrence that may entail a very
lengthy recovery period or from which it may
not be possible to recover fully. Seek medical
advice if you have doubts regarding your
health.
● People with limited pain and temperature
thresholds must never use seat heating. WARNING
If the fabric of the cushion is wet, this can ad-
versely affect the operation of the seat heat-
ing, increasing the risk of burns.
● Make sure the seat cushion is dry prior to
using the seat heater.
● Do not sit on the seat with clothing that is
wet or damp.

Diesel engines can take a few seconds longer
than usual to start on cold days. Therefore
the clutch pedal (manual gearbox) or the
brake pedal (automatic gearbox) must re-
main pressed until the engine starts up. Dur-
ing preheating, the warning lamp  remains
lit.
The preheating time depends on the coolant
and exterior temperatures. With the engine at
operating temperature, or at outside temper-
atures above +8°C, the warning lamp  will light up for about one second. This means
that the engine starts
immediately.
If the engine does not immediately start up,
interrupt the starting process and try again
after 30 seconds. To start the engine again,
return the key to position 1 .

Operation
WARNING
● Never run the engine in confined spaces, as
the exhaust gases are poisonous. 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 idling it. You
should drive off as soon as you start the en-
gine. This will help avoid unnecessary ex-
haust emissions. Note
● If it is difficult to turn the ignition key to
the position 1 , turn the steering 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 remain in the posi-
tion 1 for around 5 seconds before starting
up.
● Vehicles with automatic gearbox: after
switching off the ignition, you can only re-
move the ignition key if the selector lever is in position “P” (parking lock). Next, the se-
lector lever is locked.
Switching off the engine with the key

En g
aging the steering wheel lock
In vehicles with automatic gearbox, the igni-
tion key can only be removed when the selec-
tor lever is in position P.
– Remo

ve the key from the ignition in posi-
tion 1
››› Fig. 141
›
›› .
– Turn the steering wheel until you hear it en-
gage.
Possible vehicle theft is prevented with the
steering lock engaged. WARNING
● Never switch the engine off until the vehi-
cle is stationary. The brake servo and power
steering functions will not be completely cov-
ered 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 steer-
ing 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 particularly impor-
tant if there are children in the vehicle, as
they might otherwise be able to start the en-
gine or use power-operated equipment (e.g.
the electric windows), which could cause in-
juries. CAUTION
If the engine has been running under high
load for a long time, there is a risk of heat
building up in the engine compartment after
it has been switched off; this could cause en-
gine damage. For this reason, you should idle
the engine for approximately 2 minutes be-
fore you switch it off. Note
● After the engine is switched off the radiator
fan may run on for up to 10 minutes, even if
the ignition is switched off. It is also possible
that the fan turns itself on once more if the
coolant temperature increases due to the
heat accumulated in the engine compartment
or due to its prolonged exposure to solar ra-
diation.
● If the vehicle is stopped and the Start-Stop
system* switches off the engine, the ignition 130

Driving
remains switched on. Make sure that the igni-
tion is switched off before leaving the
vehicle, otherwise the battery could dis-
charge.
Braking and parking
Using the handbrake Fig. 142
Handbrake between the front seats. The handbrake should be applied firmly to
prevent the vehicle from accidentally rolling
away.
Always apply the handbrake when you leave
your vehicle and when you park.
Applying the handbrake
– Pull the handbrake lever up firmly
››› Fig. 142 . R
el easing the handbrake
– Pull the lever up slightly and press the re-
lease knob in the direction of the arrow
››› Fig. 142 and guide the handbrake lever
down f

ully ››› .
Always pull the handbrake all the way up, so
there is less risk of driving off with it still en-
gaged ››› .
The handbrake warning lamp  lights up
when the handbrake is applied and the igni-
tion switched on. The warning lamp turns off
when the handbrake 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 vehi-
cle when it is in motion. The braking distance
is considerably longer, because braking is
only applied to the rear wheels. Risk of acci-
dent!
● 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.
– Never leave a vehicle key in 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

D/S – Permanent drive (forward) position
The selector lever in the D/S position enables
the gears to be controlled in normal mode (D)
or Sport (S). To select Sport mode (S), move
the selector lever backwards. Moving the lev-
er again will select normal mode (D). The se-
lected driving mode is shown on the instru-
ment panel display.
In
normal mode (D), the gearbox automatical-
ly selects the best gear ratio. This depends
on the engine load, the road speed and the
dynamic gear control programme (DCP).
Sport mode (S) must be selected for a sporty
driving style. This setting makes use of the
engine's maximum power output. When ac-
celerating the gear shifts will be noticeable. The brake pedal must be pressed when mov-
ing the selector lever from D/S to N if the ve-
hicle is stationary or at speeds below 5 km/h
(3 mph)
››› .
Under certain circumstances (e.g. when driv-
ing in mountains) it can be advantageous to
switch temporarily to tiptronic mode
››› page 135 , in order to
manually select g
ear
ratios to suit the driving conditions. WARNING
● Take care not to accidentally press the ac-
celerator pedal when the vehicle is stopped.
The vehicle could otherwise start moving im-
mediately (in some cases even if the parking
brake is engaged) resulting in the risk of an
accident.
● Never move the selector lever to R or P
when driving. Failure to follow this instruc-
tion could result in an accident.
● With selector lever in any position (except
P) the vehicle must always be held with the
foot brake when the engine is running. This is
because an automatic gearbox still transmits
power even at idling speed, and the vehicle
tends to “creep”). The accelerator pedal must
on no account be pressed inadvertently when
a gear is engaged with the vehicle stationary.

Operation
●
While you are selecting a gear and the vehi-
cle is stopped with the engine running, do
not accelerate. Failure to follow this instruc-
tion could result in an accident.
● As a driver you should never leave your ve-
hicle if the engine is running and a gear is en-
gaged. If you have to leave your vehicle while
the engine is running, you must apply the
handbrake and engage the parking lock (P).
● To avoid accidents, apply the handbrake
and put the selector lever in position P before
opening the bonnet and working on the vehi-
cle with the engine running. Please always
observe the important safety warnings
››› page 198, Work in the engine compart-
ment. Note
● If the selector lever is moved accidentally
to N when driving, release the accelerator and
let the engine speed drop to idling before se-
lecting gear range D or S again.
● Should the power supply to the selector
lever be interrupted in position P, the selector
lever will be locked. If this should happen the
manual release can be used ››› page 229. Selector lever lock
Fig. 143
Selector lever lock. The selector lever lock prevents gears from
being engaged inadvertently, so that the ve-
hicle is not set in motion unintentionally.
The selector lever lock is released as follows:
– Switch the ignition on.
– Press the brake pedal and at the same time
pr e
ss in the interlock button.
Automatic selector lever lock
With the ignition switched on, the selector
lever is locked in the positions P and N. The
brake pedal must be pressed to release the
lever while pressing the release button if the
selector lever is in the position P. As a re-
minder for the driver, with the lever in posi-
tions P or N the following message will be
shown on the display: When stationary, apply footbrake while se-
lecting a gear.
The selector lever lock only works if the vehi-
cle is stationary or driving at speeds up to 5
km/h. At higher speeds the selector lever
lock in the N position is disengaged automat-
ically.
The selector lever lock is not engaged if the
selector lever is moved quickly through posi-
tion N (e.g. when shifting from R to D). This
makes it possible, for instance, to rock the
vehicle “backwards and forwards” if it is
stuck. The selector lever lock engages auto-
matically if the brake pedal is not depressed
and the lever is in position N for more than
about two seconds.
Interlock button
The interlock button on the selector lever
handle prevents the driver from inadvertently
engaging certain gears. Press the button in
to disengage the selector lever lock. The se-
lector lever positions in which the interlock
button has to be pressed are shown in the il-
lustration, highlighted in colour ››› Fig. 143.
