Fault in the automatic gearbox
A fault in the automatic gearbox can, for example, be noticeable by the follow-
ing.
▶ Only certain gears are selected.
▶ The reverse gear R cannot be used.
▶ Shifting gears in Tiptronic mode is not possible.
CAUTION
If an error occurs on the automatic transmission the help of a specialist firm
should be sought immediately - there is a risk of damaging the vehicle.
Selector lever lock
Fig. 137
Shift lock button
Read and observe and on page 122 first.
The selector lever is locked in mode P and N to prevent that the forward driv-
ing is selected accidentally, thereby setting the vehicle in motion.
The selector lever is locked only when the vehicle is stationary and at speeds
up to 5 km/h.
The selector lever lock is indicated by the illumination of the warning light
.
The selector lever is not locked when quickly moving across the position N
(e.g. from R to D). This, for example, helps to rock out a vehicle that is stuck,
e.g. in a bank of snow. The selector lever lock will engage if the lever is in posi-
tion N for more than approx. 2 seconds without the brake pedal being de-
pressed.
Releasing selector lever from mode P or N (selector lever lock)
›
Press the brake pedal and the lock button at the same time in the direction
of

» Fig. 137 .
Just depress the brake pedal, if you would like to change from the mode N to
D .
Defective selector lever lock
If the selector lever lock is defective or its power supply is interrupted (e.g. dis-
charged vehicle battery, faulty fuse), the selector lever can no longer be moved
out of position P in the normal manner and the vehicle can no longer be driven.
The selector lever must be unlocked specially » page 195.
Note
If you want to move the selector lever from mode P to mode D or vice versa,
move the selector lever quickly. This prevents that you accidentally select
mode R or N.
Manual shifting of gears (Tiptronic)

Selector lever
Read and observe and on page 122 first.
Tiptronic mode makes it possible to manually shift gears on the selector lever.
This mode can be selected both while stopping and while driving.
The currently selected gear is indicated in the display » Fig. 136 on page 122 .
The gearshift indicator should be observed when changing gear » page 40.

123Starting-off and Driving
New tyres
New tyres must firstly be “run in”, as they do not offer optimal grip at first.
Therefore, drive especially carefully for the first 500 km or so.
New brake pads
New brake pads have to first “grind in” because these do not initially have the
best possible braking effect.
Therefore, drive especially carefully for the first 200 km or so.
Tips for economical driving
To achieve the lowest possible fuel consumption, the following instructions
must be observed.
Looking ahead when driving
Avoid unnecessary acceleration and braking.
Switch in an energy saving and timely manner Observe the recommended gear » page 40.
Avoid full throttle and high speeds
Fuel consumption can be reduced by half if only three-quarters of the possible
top speed of your vehicle is used.
Reducing idling
If the vehicle is fitted with the START - STOP system there is an automatic re-
duction of the idling. If the engine is stopped on vehicles without START-STOP
system, such as when waiting in a traffic jam, the fuel economy is already
greater after 30 - 40 s than the fuel quantity which is required for engine re-
start.
Avoid short distances
When driving a short distance of less than about 4 km, the engine cannot
reach its operating temperature. As long as the engine has not reached oper-
ating temperature, the fuel consumption is significantly higher than with the
engine hot.
Pay attention to the correct tyre inflation pressure being maintained
Further information » page 176.
Avoid unnecessary ballast
Per 100 kg of weight, consumption increases by about 0.3 l/100 km. At a speed
of 100 - 120 km/h, a vehicle fitted with a roof rack cross member without a load
will use about 10 % more fuel than normal due to the increased aerodynamic
drag.
Saving electricity
Only turn on electrical consumers (e.g. seat, window and mirror heating, etc.)
for as long as necessary.
Use the cooling system economically
The air conditioning system compressor uses power from the engine when in
cooling mode, which will affect the fuel consumption.
It recommended to open the windows or the doors of a vehicle for which the
interior has been strongly heated through the effect of direct sunlight in order
to allow the heated air to escape.
The cooling system should not be on if the windows are open.

Assist systems
General information
Introduction
WARNINGThe following general information regarding the use of assistance systems
must be observed.■
The assistance systems only serve to support and do not relieve the driv-
er of the responsibility for driving the vehicle.
■
The increased safety provision, as well as the increased occupant protec-
tion provided by the assistance systems must not tempt you to take risks -
risk of accident!
■
Adjust the speed and driving style to the current visibility, weather, road
and traffic conditions.
■
The assistance systems have physical and system-related limitations. For
this reason, the driver may experience some undesired or delayed system
responses in certain situations. You should therefore always be alert and
ready to intervene!
■
Only activate, deactivate or set the assistance systems so that you have
the car fully under control in every traffic situation - risk of accident!

This chapter describes the functions of the brake and stabilization systems.
The error display is in Chapter » page 32, Warning lights .
The brake and stabilization systems are automatically activated each time the
ignition is switched on, unless otherwise indicated.WARNINGThe general information relating to the use of assistance systems must be
observed » page 127, in section Introduction .
Stability Control (ESC)
Fig. 140
Press the ESC system: Activat-
ing/deactivating TCS
Read and observe on page 127 first.
The ESC improves vehicle stability in dynamic driving situations, such as when
the vehicle starts to skid.
The ESC monitors whether the desired direction of the current vehicle motion
is occurring. In case of any deviation (e.g. over steer), the ESC automatically
brakes individual wheels to maintain the desired direction.
During an intervention of the system, the indicator light
flashes in the in-
strument cluster.
The ESC system cannot be deactivated. The
» Fig. 140 button can only be
used to deactivate the TCS » page 128.
The warning light
lights up in the instrument cluster when the ASR is deacti-
vated.
Anti-lock braking system (ABS)
Read and observe
on page 127 first.
ABS prevents the wheels locking when braking. Thus helping the driver to
maintain control of the vehicle.
127Assist systems
The intervention of the ABS is noticeable from the pulsating movements of
the brake pedal which is accompanied by noises.
When the ABS system is active, do not brake periodically or reduce the pres- sure on the brake pedal.
Traction control (TCS)
Fig. 141
Button for the TCS system: TCS
disable / enable (vehicle without
ESC)
Read and observe on page 127 first.
TCS prevents the spinning of the wheels of the driven axle. TCS reduces the
drive power transmitted to the wheels in the case of slipping wheels. Thus, for
example, driving on road surfaces with low grip is made easier.
If your vehicle is fitted with the ESC system, the ASR is integrated into the ESC
system » page 127 .
During a TCS intervention, the indicator light flashes in the instrument clus-
ter.
The TCS should normally always be enabled. The system should be deactivated
only in the following situations, for example. ▶ When driving with snow chains.
▶ When driving in deep snow or on a very loose surface.
▶ When it is necessary to “rock” a car free when it has become stuck.
The ASR can be deactivated via the
» Fig. 141 symbol button.
The warning light lights up in the instrument cluster when the ASR is deacti-
vated.
Electronic Differential Lock (EDL)
Read and observe
on page 127 first.
EDL prevents the turning of the respective wheel of the driven axle. EDL
brakes the spinning wheel, if necessary, and transmits the driving force to the
other driving wheel. Driving becomes easier on road surfaces with different
traction under each wheel of the driven axle.
EDL switches off automatically to avoid excessive heat generation on the
brake of the wheel being braked. Once the brakes have cooled down, there is
an automatic re-activation of EDL.
Driver Steering Recommendation (DSR)
Read and observe
on page 127 first.
In critical situations, the DSR provides the driver with a steering recommenda-
tion in order to stabilise the vehicle. The DSR is activated, for example, on the
right and left vehicle side when braking sharply on different road surfaces.
Brake Assist (HBA)
Read and observe
on page 127 first.
The HBA increases the braking effect and helps to reduce the braking dis-
tance.
The HBA is activated by very quick operation of the brake pedal. In order to
achieve the shortest possible braking distance, the brake pedal must be ap-
plied firmly until the vehicle has come to a standstill.
The HBA function is automatically deactivated when the brake pedal is re-
leased.
Hill Start Assist (HHC)
Read and observe
on page 127 first.
When driving on slopes, HHC allows you to move your foot from the brake ped-
al to the accelerator pedal without having to use the handbrake.
The system holds the brake pressure produced by the activation of the brake pedal for approx. 2 seconds after the brake pedal is released.
128Driving
So that an engagement of the OFF ROAD mode can take place, the following
conditions must be met.
The OFF ROAD mode is enabled.
The vehicle is moving at a speed of less than 30 km/h. The warning light
illuminates in the instrument cluster.
The following functions are integrated in the OFF ROAD mode.
▶ Downhill Drive Support » page 130.
▶ TCS OFF ROAD » page 130.
▶ EDL OFF ROAD » page 130.
▶ ABS OFF ROAD » page 130.
▶ Start-Off Assistant » page 131.
Note
If the engine stalls while driving and is started again within 30 seconds, then
OFF ROAD mode will be automatically activated.
Hill Descent Assistant
Read and observe
and on page 129 first.
The hill descent assistant (hereinafter referred to as assistant), with its auto-
matic braking action on all wheels, ensures a constant speed is maintained on
a steep slope when driving forwards and reversing.
During an intervention of the Assistants, the warning light flashes in the in-
strument cluster.
The assistant is automatically engaged under the following conditions. The engine is running.
For vehicles with Manual transmission the shift lever is in the neutral po-
sition and or the 1st, 2nd, 3rd gear, or reverse gear is engaged.
On vehicles with an automatic transmission , the selector lever is in the R,
N, D, S position or in the Tiptronic position.
The downhill gradient is at least 10 % (when driving over sleepers, the lim-
it can briefly drop to 8 %).
Neither the accelerator nor the brake pedal is operated.
Driving speed
Initiate the downhill decent at a reasonable speed up to 30 km / h the hill de-
scent assist maintains this speed when driving downhill constant.
The assistant can maintain constant speed of about 2 - 30 km / h.
If a forwards or reverse gear is engaged for vehicles with Manual transmis-
sion , the speed must be high enough to avoid stalling the engine.
By pressing the accelerator or brake pedal, the speed can be increased or re-
duced. This is true even if the shift lever is in the neutral position and the se-
lector lever in the N position. The engagement of the assistant is resumed af-
ter the pedal is released.WARNINGFor the correct operation of the assistant the road surface must be suffi-
ciently adherent. The assistant cannot properly fulfil its function on slushy
soil due to physical reasons (e.g. ice or mud). - there is a risk of an accident!
Note
During an active intervention of the assistant, the brake lights do not light up.
TCSOFF ROAD
Read and observe
and on page 129 first.
The ASR OFF ROAD makes starting and driving on an unpaved surface easier
as it partially allows wheel-spin.
Note
When disabled, the TCS » Fig. 140 on page 127 OFF ROAD mode works without
the support of the TCS OFF ROAD.
EDS OFF ROAD
Read and observe
and on page 129 first.
The EDS supports OFF ROAD vehicle traction when driving on a surface withdifferent grip under the drive wheels or when driving over bumps.
A spinning wheel or wheels are braked earlier and with more force than with
the intervention of the standard EDS system.
ABS OFF ROAD
Read and observe
and on page 129 first.
The ABS OFF ROAD supports the driver when braking on an unpaved surface
such as gravel, snow, etc.

Park Assist (hereinafter referred to as system) helps drivers park in suitable
parallel and perpendicular parking places or also to manoeuvre out of parallel
parking spaces.
The system takes over the steering movements when parking or leaving a
parking space. The driver operates the pedals and the shift lever or gear selec-
tor.
The state in which the steering wheel is operated by the system, is referred to
as parking operation.
The Park Assist is an extension of the parking aid » page 131 and operates on
the basis of data collected by the ultrasonic sensors.
For this reason, the chapter on the parking aid is to be read carefully and the safety notes are to be observed.
WARNING■ The general information relating to the use of assistance systems must
be observed » page 127, in section Introduction .■
During the parking process, the system automatically performs rapid
steering movements. While it is doing so, do not place your hands between
the steering wheel – risk of injury!
■
During a parking manoeuvre on loose or slippery surfaces (gravel, snow,
ice, etc.) you may stray from the calculated road. Therefore we suggest that
you do not use the system in such situations.
CAUTION
The correct evaluation of the parking space and the parking procedure de-
pends on the circumference of the wheels on the vehicle.■
The system only works correctly if the vehicle is fitted with the wheel size
approved by the manufacturer.
■
Abstain from using the system when the vehicle is fitted with snow chains or
a temporary spare wheel.
■
If wheels other than those approved by the manufacturer are mounted, the
resulting position of the vehicle in the parking space can differ slightly. This
can be avoided by readjusting the system at a specialist garage.
CAUTION
If other vehicles are parked behind the kerb or on it, the system can also guide
your vehicle beyond the kerb or onto it. Ensure that the wheels or the wheel
rims of your vehicle are not damaged and if necessary intervene in time.
Note
■ We recommend performing the parking at a safe speed to about 5 km / h.■The driver can stop the parking process at any time by pressing the symbol
key
» Fig. 149 on page 136 or by a driver steering intervention.
Functioning
Read and observe
and on page 135 first.
The system support is provided in the following manner.▶ While the parking space search is going on, a measurement and evaluation of
the parking space size is completed.
▶ Suitable parking spaces are shown in the display of the instrument cluster
(hereinafter only in the display).

Function
140
Information messages
140
The fatigue detection system (hereinafter referred to as system) recommends
the driver takes a break from driving when driver fatigue can be detected due
to the driver's steering behaviour.
139Assist systems
WARNING■The general information relating to the use of assistance systems must
be observed » page 127, in section Introduction .■
For the driving ability is always the driver's responsibility. Never drive if
you feel tired.
■
The system may not detect all cases where a break is needed.
■
Therefore, take regular, sufficient breaks during long trips.
■
There will be no system warning during the so-called micro-sleep.
Note
■ In some situations, the system may evaluate the driving incorrectly and thus
mistakenly recommend a break (e.g. sporty driving, adverse weather condi-
tions or poor road conditions).■
The system is designed primarily for use on motorways.
Function
Read and observe
on page 140 first.
From the start of the journey, the system evaluates steering behaviour. If,
while driving, there have been changes in the steering behaviours that are
evaluated by the system as indicating possible fatigue, a break recommenda-
tion is issued.
The system evaluates steering behaviour and recommends a break at speeds
of 65-200 km / h.
The system detects a break from driving when one of the following condi-
tions is met.
▶ The vehicle is stopped and the ignition switched off.
▶ The vehicle is stopped, the seat belt removed and the driver's door opened.
▶ The vehicle is stopped for more than 15 minutes.
If none of these conditions are met or if the driving style is not changed, the
system recommends a driving break again after 15 minutes.
Activation/deactivation
The system can be activated/deactivated via the MAXI DOT display in the
Assis-tants
menu option » page 44.
Information messages
Read and observe
on page 140 first.
In MAXI DOT display the icon appears for a few seconds and the following
message.

An audible signal is also emitted.
Tyre pressure monitoring
Introduction
This chapter contains information on the following subjects:
Save tyre pressure values
141
The tyre pressure monitoring function (hereinafter referred to as the system)
monitors the tyre pressure while driving.
If the rolling circumference of a wheel is changed, the warning light in the
instrument cluster lights up and an audible signal sounds.
Information on the procedure for the notification of change of tyre inflation
pressure » page 38 .
The system can only function properly if the tyres have the prescribed inflation
pressure and these pressure values are stored in the system.
WARNING■ The general information relating to the use of assistance systems must
be observed » page 127, in section Introduction .■
Having the correct tyre inflation pressure is always the driver's responsi-
bility. Tyre pressure should be checked regularly » page 176.
■
The system cannot warn in case of very rapid tyre inflation pressure loss,
e.g. in case of sudden tyre damage.
