KickdownIf the accelerator pedal is presseddown completely in automatic mode, the transmission shifts to a lower gear
depending on engine speed.
Fault
To prevent damage to the manual
transmission automated, the clutch is engaged automatically at high clutch
temperatures.
In the event of a fault, control indicator
g illuminates. Additionally, a
warning message is displayed in the
Driver Information Centre. Vehicle
messages 3 100.
Continued driving is restricted or not possible, depending on the fault.
Have the cause of the fault remedied
by a workshop.Brakes
The brake system comprises two
independent brake circuits.
If a brake circuit fails, the vehicle can
still be braked using the other brake
circuit. However, braking effect is
achieved only when the brake pedal
is depressed firmly. Considerably
more force is needed for this. The
braking distance is extended. Seek
the assistance of a workshop before
continuing your journey.
When the engine is not running, the
support of the brake servo unit
disappears once the brake pedal has
been depressed once or twice.
Braking effect is not reduced, but
braking requires significantly greater
force. It is especially important to bear this in mind when being towed.
Control indicator R 3 89.
Antilock brake system
Antilock brake system (ABS)
prevents the wheels from locking.ABS starts to regulate brake pressure as soon as a wheel shows a tendency to lock. The vehicle remains
steerable, even during hard braking.
ABS control is made apparent
through a pulse in the brake pedal
and the noise of the regulation
process.
For optimum braking, keep the brake
pedal fully depressed throughout the
braking process, despite the fact that the pedal is pulsating. Do not reduce
the pressure on the pedal.
After starting off the system performs
a self-test which may be audible.
Control indicator u 3 89.
Adaptive brake light
During full braking, all three brake
lights flash for the duration of ABS
control.

Fault9Warning
If there is a fault in the ABS, the
wheels may be liable to lock due
to braking that is heavier than
normal. The advantages of ABS are no longer available. During
hard braking, the vehicle can no longer be steered and may
swerve.
Have the cause of the fault remedied
by a workshop.
Parking brake
Manual parking brake9 Warning
Always apply parking brake firmly
without operating the release
button, and apply as firmly as
possible on a downhill or uphill
slope.
To release the parking brake, pull
the lever up slightly, press the
release button and fully lower the
lever.
To reduce the operating forces of
the parking brake, depress the
foot brake at the same time.
Control indicator R 3 89.
Brake assist
If the brake pedal is depressed
quickly and forcefully, maximum
brake force is automatically applied
(full braking).
Maintain steady pressure on the brake pedal for as long as full braking is required. Maximum brake force is
automatically reduced when the
brake pedal is released.
Hill start assist The system helps prevent unintendedmovement when driving away on
inclines.
When releasing the foot brake after
stopping on an incline, the brakes
remain on for a further two seconds.
The brakes release automatically as

A precondition is that forward collision
alert is not deactivated by pressing
button V.
Activation
Forward collision alert operates
automatically above 25 mph, if it is not deactivated by pressing button V,
see below.
Selecting the alert sensitivity
The alert sensitivity can be set to
near, medium or far.Press button V, the current setting is
shown on the Driver Information
Centre (DIC). Press button V again
to change the alert sensitivity.
Alerting the driver
A green illuminated vehicle ahead
control indicator A illuminates in the
instrument cluster when the system has detected a vehicle in the driving
path.
When the distance to a preceding
moving vehicle becomes too small or
when approaching another vehicle
too rapidly and a collision is imminent,
a red LED warning light is reflected
flashing in the windscreen in front of
the driver's view.
Simultaneously a warning chime
sounds. Depress the brake pedal, if it
is required by the situation.
Deactivation The system can be deactivated.
Press button V repeatedly until the
following message appears in the
DIC.

No. 715/2007 (in the latest applicable
version), taking into consideration the
vehicle weight in running order, as specified by the regulation.
The figures are provided only for the
purpose of comparison between
different vehicle variants and must
not be taken as a guarantee for the
actual fuel consumption of a
particular vehicle. Additional
equipment may result in slightly
higher results than the stated
consumption and CO 2 figures.
Furthermore, fuel consumption is

as well as road and traffic conditions.Trailer hitch
General information Only use towing equipment that has
been approved for your vehicle.
Entrust retrofitting of towing
equipment to a workshop. It may be
necessary to make changes that
affect the cooling system, heat
shields or other equipment.
Fitting of towing equipment could
cover the opening of the towing eye.
If this is the case use the coupling ball
bar for towing. Always keep the
coupling ball bar in the vehicle.
Driving characteristics and
towing tips Before attaching a trailer, lubricate
the coupling ball. However, do not do
so if a stabiliser, which acts on the
coupling ball, is being used to reduce
snaking movements.
For trailers with low driving stability
and caravan trailers with a permitted
gross vehicle weight of more than1000 kg a speed of 50 mph must not
be exceeded; the use of a stabiliser is recommended.
If the trailer starts snaking, drive more
slowly, do not attempt to correct the
steering and brake sharply if
necessary.
When driving downhill, drive in the
same gear as if driving uphill and
drive at a similar speed.
Adjust tyre pressure to the value
specified for full load 3 237.
Trailer towing Trailer loads
The permissible trailer loads are
vehicle and engine-dependent
maximum values which must not be
exceeded. The actual trailer load is
the difference between the actual
gross weight of the trailer and the
actual coupling socket load with the
trailer coupled.
The permissible trailer loads are
specified in the vehicle documents. In general, they are valid for gradients
up to max. 12 %

TPMS Sensor Matching
Process
Each TPMS sensor has a unique
identification code. The identification
code must be matched to a new
wheel position after rotating the
wheels or exchanging the complete
wheel set and if one or more TPMS sensors were replaced. The TPMS
sensor matching process should also
be performed after replacing a spare
wheel with a road wheel containing
the TPMS sensor.
The malfunction light w and the
warning message or code should go
off at the next ignition cycle. The
sensors are matched to the wheel
positions, using a TPMS relearn tool,
in the following order: left side front
wheel, right side front wheel, right
side rear wheel and left side rear
wheel. The turn signal light at the
current active position is illuminated
until sensor is matched.
Consult your workshop for service or
to purchase a relearn tool. There are
2 minutes to match the first wheel
position, and 5 minutes overall to
match all four wheel positions. If it
takes longer, the matching process stops and must be restarted.
The TPMS sensor matching process
is:
1. Apply the parking brake.
2. Turn the ignition on.3. On vehicles with automatic transmission: set the selector
lever to P.
On vehicles with manual
transmission automated: Press
and hold brake pedal. Move and
hold the selector lever for
5 seconds in position N until P is
displayed in the DIC. P indicates
that the sensor matching process
of the TPMS can be started.
On vehicles with manual
transmission: select neutral.
4. Use the MENU button on the turn
signal lever to select the Vehicle
Menu in the DIC.
5. Turn the adjuster wheel to scroll to
the tyre pressure menu.
