Driving and operating1379Warning
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 83.
Brake assist
If brake pedal is depressed quickly
and forcefully, maximum brake force
is automatically applied.
Operation of brake assist might
become apparent by a pulse in the
brake pedal and a greater resistance when depressing the brake pedal.
Maintain steady pressure on the
brake pedal as long as full braking is
required. Maximum brake force is
automatically reduced when brake
pedal is released.
Hill start assist The system helps prevent unintendedmovement when driving away on
inclines.
When releasing the brake pedal after
stopping on an incline, brakes remain on for further 2 seconds. The brakes
release automatically as soon as the
vehicle begins to accelerate.Ride control systems
Electronic Stability Control and Traction Control system
Electronic stability control (ESC)
improves driving stability when
necessary, regardless of the type of
road surface or tyre grip.
As soon as the vehicle starts to
swerve (understeer / oversteer),
engine output is reduced and the
wheels are braked individually.
ESC operates in combination with the traction control system. It prevents
the driven wheels from spinning.
The traction control system is a
component of the ESC and prevents
the driven wheels from spinning. As
soon as the driven wheels starts to
spin, engine output is reduced and
the wheel spinning the most is braked
individually. This considerably
improves the driving stability of the
vehicle on slippery road surfaces.
Driving and operating153The system will not identify slots that
are clearly smaller or larger than the
vehicle.
When a free slot is detected, a visual
feedback on the Colour Info Display
and a first acoustic signal is given.
Drive slowly forwards. When the second acoustic signal is given, stop
the vehicle, select reverse gear,
release the steering wheel and start
moving without exceeding 4 mph.
Move forwards and backwards while

blindness or serious burn
injuries.
Vehicle care195The pressure increases by nearly
1.5 psi for a 10 °C temperature
increase. This must be considered
when warm tyres are checked.
Tyre deflation detectionsystem
The tyre deflation detection system
continually checks the rotation speed
of all four wheels and warns on low
tyre pressure condition once vehicle
is driving. This is achieved by
comparing tyre rolling circumference
with reference values and further
signals.
If a tyre loses pressure the control
indicator w illuminates and a warning
message is displayed in the Driver
Information Centre.
In this case reduce speed, avoid
sharp cornering and strong braking.
Stop at next safe opportunity and
check tyre pressure.
Control indicator w 3 85.
After adjusting tyre pressure initialise
system to extinguish the control
indicator and restart system.Caution
Deflation detection system warns
just about low tyre pressure
condition and does not replace
regular tyre maintenance by the
driver.
In case of a system malfunction a
message is displayed in the Driver
Information Centre. Set correct tyre
pressure and reinitialise system. If the
failure continues to be displayed,
contact a workshop. The system is
inoperable when ABS or ESC has a
malfunction or a temporary spare
wheel is used.
In case of a system malfunction a
message is displayed in the Driver
Information Centre. Set correct tyre
pressure and reinitialise system. If the
failure continues to be displayed,
contact a workshop. The system is
inoperable when ABS or ESC has a
malfunction.
Once the road tyre has been refitted,
check the tyre pressure with cold
tyres and initialise the system.
System initialisation
After tyre pressure correction or
wheel change, the system must be
initialised to learn new circumference reference values:
1. Always ensure that all four tyres have correct tyre pressure3 227.
2. Apply parking brake. 3. Press w to reset deflation
detection system.
4. Reset is confirmed by pop-up indication.

10. Set the rocker switch on thecompressor to I. The tyre is filled
with sealant.
11. The compressor pressure gauge briefly indicates up to 6 bar whilstthe sealant bottle is emptying
(approx. 30 seconds). Then the
pressure starts to drop.
12. All of the sealant is pumped into the tyre. Then the tyre is being
inflated.
13. The prescribed tyre pressure should be obtained within
10 minutes.
Tyre pressure 3 227.
When the correct pressure is
obtained, switch off the
compressor.
If the prescribed tyre pressure is
not obtained within 10 minutes,
remove the tyre repair kit. Move
the vehicle one tyre rotation.
Reattach the tyre repair kit and
continue the filling procedure for
10 minutes. If the prescribed tyre
pressure is still not obtained, the
tyre is too badly damaged. Seek
the assistance of a workshop.
Drain excess tyre pressure with
the button on the air hose.
Do not run the compressor longer
than 10 minutes.
14. Detach the tyre repair kit. Remove
sealant bottle from bracket. Screw
the filler hose to the free connection of the sealant bottle.
This prevents sealant from
escaping. Stow tyre repair kit in
load compartment.
15. Remove any excess sealant using a cloth.
16. Continue driving immediately sothat sealant is evenly distributed
in the tyre. After driving approx.
3 miles (but no more than 10 min ),
stop and check tyre pressure.
Screw compressor air hose
directly onto tyre valve when
doing this. Fill tyre as described
