WARNING
If BAS is malfunctioning, the braking distance
in an emergency braking situation is
increased. There is a risk of an accident.
In an emergency braking situation, depress
the brake pedal with full force. ABS prevents
the wheels from locking.
Vehicles without steering wheel buttons: if
the BAS driving safety system is
malfunctioning, the 000Awarning lamp lights
up while the engine is running (Y page 210).
BAS operates in emergency braking
situations. If you depress the brake quickly,
BAS automatically increases the brake
pressure, thereby reducing the stopping
distance.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated. EBD (electronic brake force
distribution)
Note the section on 'Important safety notes'
(Y page 56). G
WARNING
If EBD has malfunctioned, the rear wheels can
still lock, e.g. under full braking. This
increases the risk of skidding and an accident.
You should therefore adapt yourd riving style
to the different handling characteristics. Have
the brake system checked at a qualified
specialist workshop.
EBD monitors and controls the brake
pressure to the rear wheels. This enables EBD
to improve handling during braking.
Observe the information on warning and
indicator lamps (Y page 210). ESP
®
(Electronic Stability Program)
Note the section on 'Important safety notes'
(Y page 56). G
WARNING
If ESP ®
is malfunctioning it willn ot provide
any vehicle stabilization. There is an increased
risk of skidding or of an accident.
Exercise caution when continuing to drive.
Have ESP ®
checked at a qualified specialist
workshop.
! Only operate the vehicle briefly
(maximum of 10 seconds) on a brake
dynamometer. The key must be turned to
position 1in the ignition lock during this
time. You could otherwise damage the
drive train or the brake system.
! Do not run the vehicle on a roller
dynamometer (e.g. for performance tests).
If you must operate the vehicle on a roller
dynamometer, please consult a qualified
specialist workshop in advance. You could
otherwise damage the drive train or the
brake system.
If you activate or deactivate ESP ®
in a vehicle
with engageable all-wheel drive, ESP ®
will be
deactivated for the duration of the
activation/deactivation process.
If ESP ®
is malfunctioning, the 0002indicator
lamp lights up while the engine is running and
the engine power may be reduced
(Y page 210).
ESP ®
monitors driving stability and detects a
tendency of the vehicle to understeer or
oversteer (skidding) in good time. If ESP ®
detects that the vehicle is deviating from the
direction desired by the driver, one or more
wheels are braked to stabilize the vehicle. The
engine output is also modified to keep the
vehicle on the desired course within physical
limits. ESP ®
greatly assists you when driving
on wet or slippery road surfaces. ESP ®
also
stabilizes the vehicle when braking.
The 000D warning lamp in the instrument
cluster flashes when ESP ®
is intervening. Driving safety systems

Useful information
This Operator's Manual describes all models
as well as standard and optional equipment

Important safety notes
For reasons of safety, we recommend that
you drive with the lights switched on even
during the daytime. There may be differences
in operation due to legal requirements and
voluntary recommendations in some
countries. Lamp failure indicator
The bulb failure indicator is only an aid. You
are responsible for the proper functioning of
the vehicle lighting. Insufficient or non-
functioning vehicle lightin gputs the operating
safety of the vehicle at risk.
For this reason, check the condition and
function of your vehicle's lighting system and,
if necessary, that of the trailer before each
journey.
The bulb failure indicator monitors all of the
exterio rlighting lamps, except the perimeter
lamp and the trailer lighting. If a bulb fails,
either the 0002(Ypage 34) indicator lamp
lights up, or you will see a corresponding
message in the display (Y page 201).
i Depending on the equipment, the bulb
failure indicator can fail for all lamps with
the exceptio nofthe turn signal lamps. Light switch

The auxiliary heating works independently of
the engine and supplements the climate
control system in the vehicle. The auxiliary
heating heats the air in the vehicle interior to
the temperature set.
If your vehicle is equipped with a hot-water
auxiliary heater, the auxiliary heating also
keeps the coolant warm. This way, the load
on the engine is minimized and fuel is saved.
The heater booster function of the auxiliary
heating supports the climate control system
when the engine is runnin gand the outside
temperature is low.
You can use the auxiliary heating at an
outside temperature of up to 39 ‡ (4 †). At
an outside temperature above 39 ‡(4† ) the
auxiliary heating system and the heater
booster function switch off automatically.
i If the interior motion sensor (Y page 61)
is armed and the auxiliary heating is
switched on, it is possible that the interior
temperature monitoring may cause a false
alarm. In this case, either deactivate the
interior motion sensor or switch off the
auxiliary heating. Before switching on
