Driving and operating129
The deactivation of the AWD system
will be indicated by a message on the
Driver Information Centre.
If a service message or warning
code S73 is displayed on the Driver Information Centre, there is a
malfunction in the AWD system. Seek the assistance of a workshop.
Vehicle messages 3 94, Towing the
vehicle 3 189.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 85.
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 86.
Adaptive brake light
During full braking, all three brake
lights flash for the duration of ABS
control.
Driving and operating141
Deactivation
The camera is deactivated when a certain forward speed is exceeded or
if reverse gear is not engaged for
approx. 10 seconds.
Activation or deactivation of the rear
view camera can be changed in the menu Settings in the Info-Display.
Vehicle personalisation 3 99.
Fault Fault messages are displayed with a9 on the top line of the Info-Display.
The rear view camera may not
operate properly when:
■ the surrounding is dark,
■ the sun or the beam of headlights is
shining directly into the camera
lens,
■ ice, snow, mud, or anything else covers the camera lens. Clean the
lens, rinse it with water, and wipe it
with a soft cloth,
■ the tailgate is not closed correctly,
■ the vehicle had a rear end accident,
■ there are extreme temperature changes.Traffic sign assistant
Functionality
The traffic sign assistant system
detects designated traffic signs via a
front camera and displays them in the
Driver Information Centre.
Traffic signs, which will be detected,
are:
Limit and no passing signs ■ speed limit
■ no passing
■ end of speed limit
■ end of no passingRoad signs
Beginning and end of:
■ motorways
■ A-roads
■ play streetsAdd on signs ■ additional hints to traffic signs
■ restriction of trailer towing
■ wet warning
■ ice warning
■ direction arrows
Speed limit signs are displayed in the
Driver Information Centre until the
next speed limit sign or end of speed
limit is detected or up to a defined sign timeout.
Driving and operating147
Pressing the LPG button switches
between petrol and liquid gas
operation as soon as the required
parameters (coolant temperature,
gas temperature and minimum
engine speed) have been reached.
The requirements are usually fulfilled
after approx. 60 seconds (depending
on exterior temperature) and the first
firm press on the accelerator. The
LED status shows the current
operating mode.LED off=petrol operationLED illu‐
minates=liquid gas operationLED
flashes=no switching is
possible, one type of
fuel is empty
As soon as the liquid gas tanks are empty, petrol operation is
automatically engaged until the
ignition is switched off.
Every six months, run the petrol tank down until control indicator i
illuminates, then refuel. This helps
maintain fuel quality and system
function for petrol operation.
Fill the tank completely at regular
intervals to prevent corrosion in the
tank.
Faults and remedies
If gas mode is not possible, check the following:
■ Is there enough liquid gas present?
■ Is there enough petrol present for starting?
Due to extreme temperatures in
combination with the gas
composition, it may take slightly
longer before the system switches
from petrol to gas mode.
In extreme situations, the system may
also switch back to petrol mode if the
minimum requirements are not
fulfilled.
Seek the assistance of a workshop in the event of all other faults.Caution
Repairs and adjustments may onlybe made by trained specialists in
order to maintain the safety and
warranty on the LPG system.
Liquid gas is given a particular odour
(odorised) so that any leaks can be
detected easily.
9 Warning
If you smell gas in the vehicle or in
the immediate vicinity, switch to petrol mode immediately. No
smoking. No naked flames or
ignition sources.
If the gas odour persists, do not start
the engine. Have the cause of the
fault remedied by a workshop.
When using underground car parks,
follow the instructions of the operator
and local laws.
Notice
In the event of an accident, switch off
the ignition and lights.
