Information messages
119
The START STOPsystem (hereinafter referred to as the system) reduces
CO 2emissions and harmful emissions, and saves fuel.
If the system determine that the engine is not needed when the vehicle stops
(e.g. at the traffic lights), it turns off the engine and starts it again when mov-
ing off.
The system function depends on many factors. Some of them are down to the
driver, the others are systemic and can neither be influenced nor identified.
Therefore the system may react differently in situations which seem identi-
cal from the driver's perspective.
The system is automatically activated every time the ignition is switched on
(even where this has previously been manually deactivated with the button ).
Note
If the engine has stopped due to the system, the ignition remains on.117Starting-off and Driving
OperationFig. 132
Prompt in the MAXI DOT display
Vehicles with manual transmission
The engine is automatically switched off as soon as the vehicle comes to a
halt, the shift lever is moved into neutral and the clutch pedal is released.
The engine is automatically started as soon as the clutch pedal is depressed.
Vehicles with automatic transmission
The engine is automatically switched off as soon as the vehicle comes to a halt
and the brake pedal is operated.
The engine is automatically started as soon as the brake pedal is released.
Requirements for the system to function correctly
The following conditions must be met for the system to function correctly.
The driver's door is closed.
The driver has fastened the seat belt.
The bonnet is closed.
The driving speed was higher than 4 km.h after the last stop.
No trailer is coupled.
System status
The system status is indicated in the instrument cluster display when stopped.
The engine is automatically switched off; when the vehicle moves off the igni-
tion process will be automatically initiated.

START-STOP NOT POSSIBLEReasons for the engine running
It may be essential for the engine to keep running when the vehicle comes to
a halt, for the following reasons. ▶ The engine temperature for the proper function of the system has not yet
been reached.
▶ The charge state of the vehicle battery is too low.
▶ The current consumption is too high.
▶ High air-conditioning or heating capacity (high fan speed, big difference be-
tween the desired and actual interior temperature).
When the engine is shut-down automatically and the system detects that the engine is required such as when the brake pedal is pressed repeatedly then
the system automatically starts the engine.
Note
■ If the vehicle remains outdoors for a long time in minus temperatures or in
direct sunlight, it can take several hours until the internal temperature of the
vehicle battery reaches a suitable temperature for proper operation of the
START STOP system.■
If the driver's seat belt is removed for more than approx. 30 seconds or the
driver's door is opened during stop mode, the engine will have to be started
manually.
■
No automatic engine shut-down takes place when a vehicle with automatic
transmission is moving at low speed (e.g. during a traffic jam) and remains sta-
tionary after pressing the brake pedal lightly. Automatic engine shutdown
takes place if you press the brake pedal down with more force.
■
For vehicles with automatic transmission there is no automatic engine shut-
down when the system detects a manoeuvring action due to a large steering
angle.

Brakes and parking
Introduction
This chapter contains information on the following subjects:
Information on braking
119
Handbrake
120
Parking
121WARNING■ Greater physical effort is required for braking when the engine is switch-
ed off – risk of accident!■
During the braking procedure on a vehicle with manual transmission,
when the vehicle is in gear and at low revs, press the clutch pedal. Other-
wise, the functionality of the brake system may be impaired – risk of acci-
dent!
■
When leaving the vehicle never leave persons leave unattended in the
vehicle who could release the brake. The vehicle could then start to move –
risk of accident!
■
Observe the recommendations on the new brake pads » page 125, New
brake pads .
CAUTION
Never let the brakes slip with light pressure on the pedal if braking is not nec-
essary. This causes the brakes to overheat and can also result in a longer brak-
ing distance and excessive wear.
Information on braking
Read and observe
and on page 119 first.
Wear-and-tear
The wear of the brake pads is dependent on the operating conditions and driv-
ing style.
The brake pads wear more quickly if a lot of journeys are completed in towns
and over short distances or if a very sporty style of driving is adopted.
If operated under severe conditions , the thickness of the brake pads must be
checked by a specialist garage between service appointments as well.
Wet roads or road salt
The performance of the brakes can be delayed as the brake discs and brake
pads may be moist or have a coating of ice or layer of salt on them in winter.
The brakes are cleaned and dried by applying the brakes several times »
.
Corrosion
Corrosion on the brake discs and dirt on the bake pads 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 »
.
119Starting-off and Driving
Long or steep slopes
Before travelling a long distance with a steep gradient, reduce speed and shift
into the next lowest gear. As a result, the braking effect of the engine will be
used, reducing the load on the brakes. Any additional braking should be com-
pleted intermittently, not continuously.
Emergency brake display
If the brakes are applied in full and the vehicle systems evaluate the situation
as dangerous for the traffic following behind, the brake light flashes automati-
cally.
After the speed was reduced below around 10 km/h or the vehicle was stop-
ped, the brake light stops flashing and the hazard warning light system
switches on. The hazard warning light system is switched off automatically af-
ter accelerating or driving off again.
Faults in the brake surface
If it is found that the braking distance has suddenly become longer and that
the brake pedal can be depressed further, the brake system may be faulty.
Visit a specialist garage immediately and adjust your style of driving appropri-
ately, as you will not know the exact extent of the damage.
Low brake fluid level
An insufficient level of brake fluid may result in problems in the brake system.
The level of the brake fluid is monitored electronically » page 33,
Brake sys-
tem .
Brake booster
The brake booster increases the pressure generated with the brake pedal. The
brake booster only operates when the engine is running.WARNINGOnly apply the brakes 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.HandbrakeFig. 134
Handbrake
Read and observe and on page 119 first.
The hand brake is used when stopping and parking for securing the vehicle
against unwanted movement.

›
Pull the handbrake lever firmly upwards.
Release
›
Pull the handbrake lever up slightly and at the same time push in the lock
button » Fig. 134 .
›
Move the lever right down while pressing the lock button.
The handbrake indicator light lights up when the handbrake is applied, pro-
vided the ignition is on.
A warning signal sounds if the vehicle is inadvertently driven off with the
handbrake applied.
The following message is shown in the MAXI DOT display.
Release parking brake!
The handbrake warning is activated if the vehicle is driven at a speed of more
than around 5 km/h for more than 3 seconds.
WARNINGPlease note that the handbrake must be fully released. A handbrake which
is only partially released can result in the rear brakes overheating. This can
have a negative effect on the operation of the brake system – risk of acci-
dent!120Driving
Automatic transmission
Introduction
This chapter contains information on the following subjects:
Modes and use of selector lever
122
Selector lever lock
123
Manual shifting of gears (Tiptronic)
123
Starting-off and driving
124
The automatic transmission performs automatic gear changes.
The modes of the automatic transmission can be adjusted by the driver by
means of the selector lever.
WARNING■ No throttle when it is set before starting the mode for moving forward
with the selector lever - there is a risk of accident!■
Never move the selector lever to mode R or P when driving – risk of an
accident!
■
If the vehicle is in the mode selected D, S , R or Tiptronic and the engine
stops when at idle speed, then the brake pedal must be pressed. Even
when the engine is idling, the power transmission is never completely in-
terrupted – the vehicle creeps.
■
When leaving the vehicle, the selector lever is always to put in the P
mode. Otherwise, the vehicle could be set in motion - risk of accident!
CAUTION
■ If the selector lever is moved to mode N while driving, the accelerator pedal
must be released and you will need to wait until the engine has reached its
idling speed before moving the selector lever to a forward driving mode again.■
When the outdoor temperature is below -10 ° C, the selector lever when
starting must always be in P mode.
■
When stopping on a slope, never try to hold the vehicle using the accelerator
pedal – this may lead to gear damage.
Note
After the ignition is switched off, the ignition key can only be withdrawn if the
selector lever is in the position P.Modes and use of selector leverFig. 136
Selector lever/display
Read and observe and on page 122 first.
When the ignition is switched on, the gearbox mode and the currently selected
gear are indicated in the display » Fig. 136.
The following modes can be selected with the selector lever » Fig. 136.
P
– Parking mode
The driven wheels are locked mechanically in this mode.
The parking mode must only be selected when the vehicle is stationary.
R
- Reverse gear
Reverse gear can only be engaged when the vehicle is stationary and the en-
gine is at idling speed.
N
- Neutral
The power transmission to the drive wheels is interrupted in this mode.
D
- Mode for forwards travel (normal programme)
In mode D, the forward gears are automatically changed according to the en-
gine load, accelerator pedal actuation and driving speed.
S
- Mode for forwards travel (sports programme)
In mode S , the forward gears are shifted automatically up and down at high-
er engine speeds than in mode D.
Before changing to mode S from mode D, press the lock button in the direction

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
1
» 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)
Fig. 138
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
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 » page 119, Information on braking .■
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 overrevving.
Starting-off and driving

Stopping (while the car is moving)
›
Depress the brake pedal and bring the vehicle to a stop.
›
Keep holding the brake pedal until driving is resumed.
The selector lever position N does not have to be selected when stopping for a
short time, such as at a cross roads.
Kickdown
The kickdown function allows you to achieve the maximum acceleration of
your vehicle while driving.
When the accelerator pedal is fully depressed, the kickdown function is activa-
ted in any forward driving mode.
The gearbox shifts down one or more gears depending on the vehicle speed
and engine speed, and the vehicle accelerates.
The gearbox does not shift up into the highest gear until the engine has
reached its maximum revolutions for this gear range.

Remove your foot from the accelerator pedal (the speed is higher than 20
km/h).
The vehicle moves without the braking effect of the engine.
The gear is automatically inserted again by depressing either the accelerator
or brake pedal.
WARNINGRapid acceleration, particularly on slippery roads, can lead to loss of control
of the vehicle – risk of accident!

Tips for economical driving
125
The fuel consumption, degree of pollution and vehicle wear depend on driving
style, road condition, weather conditions and the like.
Running-in
Driving in the engine
The engine has to be run in during the first 1 500 kilometres. During this peri-
od, the driving style decides on the quality of the driving-in process.
During the first 1 000 km we recommend not driving faster than 3/4 of the
maximum permissible engine speed, not to drive at full throttle and to dis-
pense with the trailer.
In the area of 1,000 to 1,500 kilometres the engine load can be increased up
to the maximum permitted engine speed.

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!

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.
