ing a vehicle with automatic transmission must always be in P mode. 84Driving
The wear and tear on the brake pads is dependent on the operating condi-
tions and driving style. In difficult conditions (e.g. urban, sporty driving), the
condition of the brakes should be checked between services by a specialist ga-
rage.
Brake response can be slower if the brakes are covered in moisture or, in win-
ter, have a layer of ice or salt on them . The brakes should be cleaned and
dried by applying the brakes many times over »
.
Corrosion on the brake discs and dirt on the brake pads can occur if the vehicle
has been parked for a long period and if you do not make much use of the
braking system. The brakes are cleaned by applying the brakes several times
over »
.
Before negotiating a long or steep gradient , reduce speed and shift down a
gear. As a result, the braking effect of the engine will be used, reducing the
load on the brakes. If, nevertheless, there is a need for additional braking, it
should be carried out at intervals.
Emergency braking warning - if it is necessary to brake hard, the system may
cause the brake lights to automatically flash, to alert the traffic behind.
New brake pads must first be ““run in”” because these do not initially have the
best possible braking effect. Drive especially carefully for the first 200 km or
so.
If the brake fluid level is too low, it can cause faults in the braking system ;
the warning light will illuminate in the instrument cluster
» page 30,
Braking system
. If the warning light does not light up, yet the stopping dis-
tance is perceived to be longer than before, the driving style should be adap-
ted in view of the unknown cause of the problem, and braking kept to a mini-
mum - seek the help of a specialist garage without delay.
The brake booster increases the pressure generated with the brake pedal. The
brake booster only operates when the engine is running.
WARNING■ Greater physical effort is required for braking when the engine is switch-
ed off – risk of accident!■
The clutch pedal must be actuated when braking on a vehicle with man-
ual transmission, when the vehicle is in gear and at low revs. Otherwise,
the functionality of the brake system may be impaired – risk of accident!
WARNING (Continued)■ Do not depress the brake pedal, if there is no requirement to slow down.
This causes the brakes to overheat and can also result in a longer braking
distance and excessive wear - risk of accident!■
Only brake for the purpose of drying and cleaning the brake discs if the
traffic conditions permit this. Do not place any other road users in jeopardy.
■
Recommendations for new brake pads should be followed.
■
When stopping and parking, the parking brake should always be applied
firmly, otherwise the vehicle could move off - risk of accident!
■
If a front spoiler, full wheel trim, etc. is mounted retrospectively, it must
be ensured that the air supply to the front wheel brakes is not reduced.
Otherwise, the front brakes could be in danger of overheating – risk of acci-
dent!

lights up when the handbrake is applied, pro-
vided the ignition is on.
87Starting-off and Driving
A warning signal sounds if the vehicle is inadvertently driven off with the
handbrake applied. The handbrake warning is activated if the vehicle is driven
at a speed of over 5 km/h for more than 3 seconds.WARNINGDisengage the handbrake completely. A handbrake which is only partially
disengaged can result in the rear brakes overheating. This can have a nega-
tive effect on the operation of the brake system – risk of accident!

Selector lever lockFig. 105
Shift lock button
Read and observe and on page 89 first.
The selector lever is locked in modes P and N to prevent the forwards travel
mode from being selected accidentally and 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 .
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. 105 .
To move the selector lever from mode N to D / S only the brake pedal is press-
ed.
The selector lever is not locked when quickly moving across the position N
(e.g. from R to D/S ). 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.
If it is not possible to release the gear selector from mode P in the usual man-
ner, then this can be emergency unlocked » page 149.
Note
If you want to switch the selector lever from mode P to mode D/S or vice ver-
sa, move the selector lever quickly. This prevents modes R or N from being ac-
cidentally selected.Manual shifting (Tiptronic)Fig. 106

» Fig. 106.
The currently selected gear is indicated in the display » Fig. 104 on page 89 .
The gearshift indicator should be observed when changing gear » page 38.
When accelerating, the gearbox automatically shifts up into the higher gear
just before the maximum permissible engine speed is reached. If a lower gear
is selected, the gearbox does not shift down until there is no risk of the engine
over revving.
Note
It may be beneficial, for example, when travelling downhill, to use manual
shifting of gears. Shifting to a lower gear reduces the load on the brakes and
hence the wear of the brakes.90Driving
The following instructions must be observed if vehicle damage is to be avoided
when driving through water (e.g. flooded roads).›
Therefore determine the depth of the water before driving through water.
The water level must not go above the web of the lower beam » Fig. 108.
›
Drive at no more than walking pace, otherwise a wave may form in front of
the vehicle, which could cause the water to enter into the vehicle’s systems
(e.g. the air intake system for the engine).
›
Never stop in the water, do not reverse and do not switch the engine off.
CAUTION
■ If water gets into the vehicle’s systems (e.g. the air intake system for the en-
gine) it can cause serious damage to the vehicle!■
Oncoming vehicles can generate water waves which can exceed the permis-
sible water level for your vehicle.
■
Do not drive through salt water, as the salt can cause corrosion. A vehicle
coming into contact with salt water is to be thoroughly rinsed with fresh wa-
ter.
Assist systems
General information
Introduction
WARNING■
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 enable, disable or set the assistance systems so that you have the
vehicle fully under control in every traffic situation - risk of accident!

The error display is in Chapter » page 29, Warning lights .
93Assist systems
WARNINGThe general information relating to the use of assistance systems must be
observed » page 93, in section Introduction .
Stability Control (ESC)
Read and observe
on page 94 first.
The ESC improves vehicle stability when driving at the limit (e.g. if the vehicle
starts to skid) by braking individual wheels to maintain the desired direction.
If there is an ESC intervention, the warning light flashes in the instrument
cluster.
Anti-lock braking system (ABS)
Read and observe
on page 94 first.
ABS prevents the wheels locking when braking. Thus helping the driver to
maintain control of the vehicle.
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.
Engine drag torque control (MSR)
Read and observe
on page 94 first.
MSR counteracts the tendency of the drive wheels to lock during downshifts
or sudden deceleration (e.g. on icy or an otherwise slippery road surface).
If the drive wheels should lock, then the engine speed is automatically in-
creased. This reduces the braking effect of the engine and the wheels can ro-
tate freely again.
Traction control (TCS)Fig. 109
Button for the TCS system:
Read and observe on page 94 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.
During a TCS intervention, the indicator light flashes in the instrument clus-
ter.
The deactivation/activation of TCS can be carried out, depending on equip-
ment, in one of the following ways. ▶ Infotainment » Owner's Manual - Infotainment .
▶ By pressing the
» Fig. 109 button.
With deactivation , the warning light lights up in the instrument cluster
and
an appropriate message is displayed in the instrument cluster.
With activation , the warning light
is
extinguished and an appropriate mes-
sage is displayed in the instrument cluster.
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 “rocking a car free” when it has become stuck.

If, during the control, it is necessary to exceed the speed limit (e.g. to over-
take), the accelerator pedal must be pressed fully.
When exceeding the speed limit (e.g. driving down a hill), an acoustic signal
sounds and the warning light flashes in the instrument cluster.
The regulation is resumed once the speed has fallen below the set limit.
