abbreviated form. Confirm warning
messages with the multifunction
control 3 86.
Warning chimes When starting the engine or
whilst driving ■ If seat belt is not fastened.
■ If a door or the tailgate is not fully closed when starting-off.
■ If a certain speed is exceeded with the parking brake applied.
■ If the speed programmed at the factory is exceeded.
■ If the vehicle has manual transmission automated and the
driver's door is opened when theengine is running, a gear is
engaged and the foot brake is not
depressed.
■ Warning signal sounds three times if the rear carrier system is
extended and reverse gear is
selected.
When the vehicle is parked and
the driver's door is opened ■ When the key is in the ignition switch.
■ With exterior lights on.
■ For manual transmission automated, if the parking brake is
not applied and no gear is engaged when the engine is switched off.
During an Autostop ■ If the driver's door is opened.
Battery voltage Low battery voltage in the radio
remote control. On vehicles without
check control, the message InSP3

instrument panel. In some models
InSP4 illuminates together with A in
the instrument. Consult a workshop.
Lighting
Important exterior lighting lamps,
including cables and fuses, are

signal is automatically deactivated.
For three flashes, e.g. when changing lanes, press the lever until resistance
is felt and then release. This function
can be activated or deactivated
depending on the key used 3 95.
Move the lever to the resistance point

Driving and operating129
ABS starts to regulate brake pressureas soon as a wheel shows a tendency to lock. The vehicle remains
steerable, even during hard braking.
ABS control is made apparent though
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 82.
Adaptive brake light
During full braking, all three brake
lamps flash for the duration of ABS
control.Fault9 Warning
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
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.
