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.

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.

■ The TPMS sensor matchingprocess was not done or not
completed successfully after
rotating the tyres. The malfunction
light and the warning message or
code should go off after
successfully completing the sensor matching process. See "TPMS
Sensor Matching Process" later in
this section.
■ One or more TPMS sensors are missing or damaged. The warning
message or code and the
malfunction light should go off
when the TPMS sensors are
installed and the sensor matching
process is performed successfully.
Consult your workshop for service.
■ Replacement tyres or wheels do not match the original equipment
tyres or wheels. Tyres and wheels other than those recommended
could prevent the TPMS from
functioning properly.
■ Operating electronic devices or being near facilities using radio
wave frequencies similar to theTPMS could cause the TPMS
sensors to malfunction.
If the TPMS is not functioning
properly, it cannot detect or signal
a low tyre condition. Consult your
workshop for service if the TPMS
malfunction light and a warning
message or code come on and stay on.
TPMS Sensor Matching
Process Each TPMS 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 TPMS
sensors. The TPMS sensor matching process should also be performed
after replacing a spare tyre with a
road tyre containing the TPMS
sensor.
The malfunction light and the warning
message or code should go off at the
next ignition cycle. The sensors are
matched to the tyre/wheel positions,
using a TPMS relearn tool, in the
following order: driver side front tyre,
passenger side front tyre, passengerside rear tyre, and driver side rear.
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 TPMS sensor matching process
is:
1. Apply the parking brake.2. Turn the ignition on.
3. Use the MENU button on the turn
signal lever to select the Vehicle
Information Menu in the Driver
Information Centre (DIC).
4. Use the thumbwheel to scroll to the tyre pressure menu.
5. Press the SET/CLR button to
begin the sensor matching
process. A message requesting
acceptance of the process should
display.

lubricants and parts
Recommended fluids andlubricants Only use products that meet the
recommended specifications.
Damage resulting from the use of
products not in line with these
specifiations will not be covered by
the warranty.9 Warning
Operating materials are
hazardous and could be
poisonous. Handle with care. Pay
attention to information given on
the containers.
Engine oil
Engine oil is identified by its quality
and its viscosity. Quality is more
important than viscosity when
selecting which engine oil to use. The oil quality ensures e.g. engine
cleanliness, wear protection and oil
aging control, whereas viscosity
grade gives information on the oil's
thickness over a temperature range.
Dexos is the newest engine oil quality
that provides optimum protection for
gasoline and diesel engines. If it is unavailable, engine oils of other listed qualities have to be used.
Recommendations for gasoline
engines are also valid for
Compressed Natural Gas (CNG),
Liquified Petroleum Gas (LPG) and
Ethanol (E85) fuelled engines.
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 199.
Topping up engine oil
Engine oils of different manufacturers
and brands can be mixed as long as
they comply with the required engine
oil quality and viscosity.
Use of engine oil with only
ACEA A1/B1 or only A5/B5 quality is
prohibited, since it can cause long-
term engine damage under certain
operating conditions.
196Service and maintenance
Select the appropriate engine oil
based on its quality and on the
minimum ambient temperature
3 199.
Additional engine oil additives
The use of additional engine oil
additives could cause damage and
invalidate the warranty.
Engine oil viscosity grades
The SAE viscosity grade gives
information of the thickness of the oil.
Multigrade oil is indicated by two
figures, e.g. SAE 5W-30. The first
figure, followed by a W, indicates the
low temperature viscosity and the
second figure the high temperature viscosity.
Select the appropriate viscosity grade
depending on the minimum ambient
temperature 3 199.
All of the recommended viscosity
grades are suitable for high ambient
temperatures.Coolant and antifreeze
Use only organic acid type-long life
coolant (LLC) antifreeze approved for
the vehicle. Consult a workshop.
The system is factory filled with
coolant designed for excellent
corrosion protection and frost
protection down to approx. -28 °C. In
northern countries with very low
temperatures the factory filled coolant
provides frost protection down to
approx. -37 °C. This concentration
should be maintained all year round.
The use of additional coolant
additives that intend to give additional
corrosion protection or seal against
minor leaks can cause function
problems. Liability for consequences
resulting from the use of additional
coolant additives will be rejected.
Brake and clutch fluid
Over time, brake fluid absorbs
moisture which will reduce braking
effectiveness. The brake fluid should
therefore be replaced at the specified
interval.
