144Driving and operatingDrive away function
With the engine running, selecting a
forward gear (manual transmission)
or engaging D (automatic
transmission) and then depressing
the accelerator pedal automatically
releases the electrical parking brake.
This is not possible when the switch
m is pulled at the same time.
This function also helps driving away
on inclines.
Aggressive drive away may reduce
life time of wear parts.
Dynamic braking when vehicle is
moving
When the vehicle is moving and the
switch m is kept pulled, a warning
chime will sound and the electrical
parking brake system will decelerate
the vehicle, but will not apply
statically.
As soon as the switch m is released,
dynamic braking will be stopped.
Fault
Failure mode of electrical parking
brake is indicated by control indicator
j 3 85.In the event of a fault, to apply
electrical parking brake: pull and hold the switch m for a few seconds. If
control indicator m illuminates,
electrical parking brake has been applied successfully.
To release electrical parking brake:
push and hold the switch m for a few
seconds. If control indicator m
extinguishes, electrical parking brake
has been released successfully.
If control indicator m flashes:
electrical parking brake is not fully applied or released. When m is
continuously flashing, with ignition
switched on depress brake pedal,
release electrical parking brake and
retry applying.
If m continues to flash, do not drive
the vehicle. If necessary, place
wedge blocks or equivalent in front of and behind wheels to prevent vehicle movement. Seek the assistance of a
workshop to have the cause of the
fault remedied.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 2 seconds. The
brakes release automatically as soon as the vehicle begins to accelerate.
Driving and operating147temperatures may differ according to
vehicle conditions or outside
conditions.
Flashing or illumination of the yellow
control indicator u reminds the driver
that the friction material needs to cool
down: drive the vehicle without
braking as much as possible. If the
control indicator does not extinguish,
have the cause of the fault remedied
by a workshop.
DSC control indicators u 3 86.
Automatic level control
The rear level of the vehicle is
automatically adjusted to the load
conditions while driving. Suspension
and ground clearance are increased,
which improves driving conditions.
The automatic level control is
activated after the vehicle has been
driven for some distance, depending
on the vehicle load and the road
conditions.
Do not use full payload in the event of
a fault. Have the cause of the fault
remedied by a workshop.

attention.
The driver accepts full
responsibility when driving the
vehicle.
When using driver assistance
systems, always take care
regarding the current traffic
situation.
Cruise control
The cruise control can store and
maintain speeds above 40 km/h.
Deviations from the stored speeds
may occur when driving uphill or
downhill.
For safety reasons the cruise control
cannot be activated until the foot

The system is deactivated
automatically when the vehicle speed is above 8 km/h or when selector
lever is in neutral (automatic
transmission in N or P).
If b is pressed again, the LED in the
button will extinguish and the system
will be reactivated as soon as a
forward gear or reverse gear is
engaged and the electrical parking brake is released.
Fault
In the event of a fault in the system,
control indicator r illuminates in the
instrument cluster.If the acoustic signal sounds 3 times
continuously when there are no
obstacles near the front or rear
bumper, there is a fault in the system. Have the cause of the fault remedied
by a workshop.
Important hints for using the
parking assist system9 Warning
Under certain circumstances,
various reflective surfaces on
objects or clothing as well as
external noise sources may cause the system to fail to detect
obstacles.

Vehicle care185If the tyre pressure is to be reduced or
increased, switch off the ignition. Tyre
pressures 3 182, 3 212.
General information The use of commercially available
liquid tyre repair kits can impair the
function of the system. Factory-
approved tyre repair kits can be used.
Tyre repair kit 3 187.
Operating electronic devices or being close to facilities using similar wave
frequencies could disrupt the tyre
pressure monitoring system.
The tyre pressure monitoring system
valve cores and sealing rings must be
replaced each time the tyres are
changed.
Tyre pressure sensor matching
process
Each tyre pressure sensor has a
unique identification code. The
identification code must be matched
to a new tyre/wheel position after
rotating the tyres or replacing one or
more of the tyre pressure sensors.The tyre pressure sensor matching
process should also be performed
after replacing a spare tyre with a
road tyre containing a tyre pressure
sensor. The control indicator w and
the warning message should
extinguish at the next ignition cycle.
The sensors are matched to the tyre/
wheel positions, using a TPMS
relearn tool, in the following order:
● left front tyre
● right front tyre
● right rear tyre
● left rear tyre
Consult your workshop for service or
to purchase a relearn tool.
There are two minutes to match the
first tyre/wheel position, and
five minutes overall to match all four
tyre/wheel positions. If it takes longer, the matching process stops and must
be restarted.The tyre pressure sensor matching
process is as follows:
1. Apply the electrical parking brake 3 143 ; on vehicles with automatic
transmission move the selector
lever to position P.
2. Turn the ignition on 3 125.
3. Initiate the TPMS Learn Mode by simultaneously pressing p and
q on the radio remote control,
