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 en
gine 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,

WARNING
● Never ru n the en
gine in confined spaces, as
the exhaust gases are poisonous. CAUTION
Avoid high engine speeds, full throttle and
extr eme lo
ad 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
shoul d driv
e off as soon as you start the en-
gine. This will help avoid unnecessary ex-
haust emissions. Note
● If it i
s difficult to turn the ignition key to
the position 1 , turn the steering wheel to
both side s
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
reconnect
ed, the key must remain in the posi-
tion 1 for around 5 seconds before starting
up.
● Vehic
les with automatic gearbox: after
switc
hing off the ignition, you can only re-
move the ignition key if the selector lever is in position “P” (parking lock). Next, the se-
lect

● Never sw it
ch 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 r emo
ve 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
leav
e 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
loa d f
or 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
● Aft er the en
gine 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.

Always apply the handbrake when you leave
your vehicle and when you park.
Applying the handbrake
– Pull the handbrake lever up firmly
›››
Fig. 186. Releasing the handbrake
– Pull the lever up slightly and press the re-
lea
se knob in the direction of the arrow
››› Fig. 186 and guide the handbrake lever

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 audi-
ble warning. WARNING
● Never u se the h
andbrake 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 w
ill 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 v ehic
le. Put it in 1st gear as well. Parking
The handbrake should always be firmly ap-
plied when the
v
ehicle 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. T
urn the steering wheel
slightly to engage the steering lock.
– Never leave a vehicle key in the vehicle.

P – Parking lock
When the selector lever is in this position,
the driven wheels are locked mechanically.
The parking lock must be engaged only when
the vehicle is stationary ››› .
The int erloc
k
button (the button on the selec-
tor lever handle) must be pressed in and si-
multaneously the brake pedal must be de-
pressed before moving the selector lever ei-
ther in or out of position P. R – Reverse gear
Rever
se gear must be engaged only when the
vehicle is stationary and the engine is idling
››› .
T o mo
v
e the selector lever to position R, the
interlock button must be pressed in and at
the same time the brake pedal must be de-
pressed. The reverse lights come on when
the selector lever is in the R position with the
ignition on.
N – Neutral (idling)
With the selector lever in this position, the
gear is in neutral.
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 select
or lever from D/S to N if the ve-
hicle is stationary or at speeds below 5 km/h
(3 mph) ››› .
Under c er
t
ain circumstances (e.g. when driv-
ing in mountains) it can be advantageous to
switch temporarily to tiptronic mode
››› page 170, in order to manually select gear
ratios to suit the driving conditions. WARNING
● Tak e c
are 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. F
ailure to follow this instruc-
tion could result in an accident.
● With selector lever in any position (except
P) the vehic
le 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.
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.
● While you are selecting a gear and the vehi-
cle i
s stopped with the engine running, do 168
Driving
not accelerate. Failure to follow this instruc-
tion cou
l
d 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 sel
ector 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 246, Work in the engine compart-
ment. Note
● If the sel ect
or 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 int
errupted in position P, the selector
lever will be locked. If this should happen the

aged 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
press 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 selecting a gear.
The selector l
ever 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. 187.
