Driving
●
Never u se s
prays to cold start the engine. CAUTION
● The s tar
ter motor or the engine may be
damaged if you try to start the engine while
driving or if you restart it immediately after
switching it off.
● If the engine is cold, avoid high engine
speeds, p
ushing the engine too hard and rap-
id acceleration.
● Do not start the engine by pushing the ve-
hicle or t
owing it. Unburnt fuel could enter
the catalytic converter and damage it. Note
● Do not w ait
until the engine warms up with
the vehicle stationary; if you have good visi-
bility through the windows, start driving im-
mediately. This helps the engine reach oper-
ating temperature faster and reduces emis-
sions.
● Electrical components with a high power
cons
umption are switched off temporarily
when the engine starts.
● When starting with a cold engine, noise
level
s may briefly increase. This is quite nor-
mal, and no cause for concern.
● When the outside temperature is below
+5°C (+41°F), if the en
gine is diesel, some
smoke may appear under the vehicle when
the fuel-operated auxiliary heater is on. Stopping the engine

Po w
er steering does not work when the en-
gine is not running. You need more strength
to steer when the engine is switched off.
● If the ignition is switched off, the steering
column c
ould be locked, making it impossible
to control the vehicle. CAUTION
If the engine is made to work hard for a long
time, it ma
y overheat after being switched
off. To prevent damage to the engine before
switching it off, leave it idle for approx. 2 mi-
nutes in neutral. Note
After switching off the engine, the cooling fan
ma y
continue to operate in the engine com-
partment for a few more minutes, even with
the ignition off. The radiator fan is automati-
cally switched off. “My Beat” Function

Operation
Under certain circumstances (e.g. when driv-
in g in mou
nt
ains) it can be advantageous to
switch temporarily to tiptronic mode
››› page 195, 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
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 i
s
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 298, Working 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
manual release can be used ›››

manent manual gear change using the
gearshift paddles, move the selector lever
from position D/S to the right. When accelerating, the gearbox automatical-
ly shifts
up into the next gear shortly before
the maximum engine speed is reached.
If you select a lower gear, the automatic gear-
box will not shift down until there is no risk of
over-revving the engine.
When the kick-down feature is used, the
gearbox shifts down to a lower gear, depend-
ing on road speed and engine speed.

B a
s
ic requirements for the Start-Stop mode
● The driver door must be closed.
● The driver must have their seat belt fas-
tened. ●
The bonnet mus
t be closed.
● The engine must have reached a minimum
servic
e temperature.
● The reverse gear must not be engaged.
● The vehicle must not be on a very steep
slope. WARNING
● 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 remove the key from the ignition if
the vehic
le is in motion. Otherwise, the steer-
ing could lock making it impossible to steer
the vehicle.
● To avoid injury, make sure that the Start-

– Before stopping the vehicle or when it is
stop
ped, put it into neutral and release the
clutch pedal. The engine will switch off. The
warning lamp will appear on the instru-
ment panel display. The engine may stop
before the vehicle comes to a halt in the
deceleration phase (at 7 km/h).
– When the clutch pedal is pressed the en-
gine wil
l start up again. The warning lamp
will switch off.
Vehicles with an automatic gearbox – Use the foot brake to bring the vehicle to a
stop and k
eep the brake pedal pressed
down with your foot. The engine will switch
off. The warning lamp will appear in the
display. The engine may stop before the ve-
hicle comes to a halt in the deceleration
phase (at 7 km/h or 2 km/h, depending on
the vehicle’s gearbox).
– When you take your foot off the brake pedal
the engine wi
ll start up again. The warning
lamp will switch off. In vehicles with the Au-
to Hold* system, when the system is active,
the engine will not start if you remove your
foot from the brake pedal. The car starts
when you press the accelerator pedal. 1)

earbox
The engine stops when the selector lever is in
the positions P, D, N and S, in addition to
when in manual mode. With the selector lev-
er in position P, the engine will also remain
switched off when you take your foot off the
brake pedal. In order to start the engine up
again the accelerator must be pressed, or an-
other gear engaged or the brake released.
If the selector lever is placed in position R
during the stopping phase, the engine will
start up again.
Change from position D to P to prevent the
engine from accidentally starting when
changing and passing by position R.
Additional information about vehicles with
Adaptive Cruise Control (ACC)
In vehicles with ACC function, the engine will
start up again in certain operating conditions
if the radar sensor detects that the vehicle
ahead drives off again. Note
● In v ehic
les with an automatic gearbox, you
can control whether the engine should switch
off or not by reducing or increasing the brake
force applied. While the vehicle remains stop-
ped, the engine will not stop if the brake ped-
al is slightly pressed, in traffic jams with fre-
quent stopping and starting for example. As soon as strong pressure is applied to the
brak
e ped
al, the engine will stop.
● In vehicles with manual gearbox, during
the stop
ping phases the brake pedal must re-
main depressed to prevent the vehicle from
moving.
● If the engine “stalls” in vehicles with man-
ual g
earbox, it can be directly started up
again by immediately pressing the clutch
pedal. General notes

The engine does not switch off
Before the stopping phase, the system veri-
fies whether certain conditions are met. The
engine does not switch off, in the following
situations for example:
● The engine has not yet reached the mini-
mum required t
emperature for the Start-Stop
mode.
● The interior temperature selected for the air

alid for vehicles: 4Drive
Hi
ll Descent Control limits the speed on steep
descents by automatically braking all four
wheels, both when moving forward and in re-
verse. As the anti-lock brake system remains
active, it prevents the wheels from locking. In
vehicles with manual transmission, the Hill
Descent Control adapts the theoretical speed
without slowing the engine below its idling
speed. After starting the descent of a slope below
30 km/h (18 mph), speed i
s
limited to a min-
imum of 2 km/h (1 mph) and a maximum of
30 km/h (18 mph). When appropriate, the
driver may increase or decrease the speed
within the limit by pressing the accelerator or
the brake. At this point the function is inter-
rupted and, if necessary, it is then reactiva-
ted.
Even so, it is imperative that the surface
guarantees sufficient adhesion. For this rea-
son, the Hill Descent Control will not fulfil its
function when, for example, descending a
slope with a frozen or slippery surface.
Hill Descent Control is available when the
dash panel display shows the message .
Hill Descent Control automatically intervenes
if the following conditions are met:
● The vehicle engine is running.
● The Offroad driving profile has been selec-
