72Instruments and controls
If the message BRAKING FAULT
appears in the Driver Information
Centre there is a fault in the braking
system. Seek the assistance of a
workshop immediately.
Brake system 3 101.
Antilock brake system
(ABS)
u illuminates yellow.
Illuminates briefly after the ignition is
switched on. The system is ready for
operation when u goes out.
If control indicator u does not go out
after a few seconds, or if it illuminates while driving, there is a fault in the
ABS. Control indicator A may also
illuminate in the instrument cluster together with the messages CHECK
ABS and CHECK ESP in the Driver
Information Centre. The brake
system remains operational but
without ABS regulation.
If control indicators u, A , R and
C illuminate, the ABS and ESP are
deactivated and the message
BRAKING FAULT appears in theDriver Information Centre. Seek the
assistance of a workshop
immediately.
Antilock brake system 3 101.
Upshift k or j illuminates green.
It is recommended to shift gear when
illuminated to improve fuel economy.
Electronic Stability
Program
v flashes or illuminates yellow.
Illuminates for a few seconds when
the ignition is switched on.
Flashing during driving
The system is actively engaged.
Engine output may be reduced and
the vehicle may be braked
automatically to a small degree.
Illuminates while driving
The system is switched off. The
message ESP OFF will also appear in
the Driver Information Centre.ESP® Plus
3 103.
Engine coolant
temperature W illuminates red.
Illuminates when the engine is running Stop, switch off engine.Caution
Coolant temperature too high.
Check coolant level 3 119.
If there is sufficient coolant, consult a workshop.
Preheating
! illuminates yellow.
Preheating is activated. Only
activates when outside temperature
is low.
120Vehicle care
If the cooling system is cold, the
coolant level should be just above the
MIN mark. Top up if the level is low.
9Warning
Allow the engine to cool before
opening the cap. Carefully open
the cap, relieving the pressure
slowly.
Top up with antifreeze. If no
antifreeze is available, use clean tap
water or distilled water. Install the cap
tightly. Have the antifreeze
concentration checked and have the
cause of the coolant loss remedied by a workshop.
If a substantial amount of coolant is
required, it will be necessary to bleed
any trapped air from the cooling
system. Seek the assistance of a
workshop.
If the coolant temperature is too high, control indicator W illuminates red in
the instrument cluster, together with
C 3 72. Consult a workshop if
coolant level is sufficient.
Power steering fluidIf the fluid level in the reservoir falls
below the MIN mark consult a
workshop.
Washer fluid
Fill with clean water mixed with a
suitable quantity of windscreen
washer fluid which contains
antifreeze.
148Service and maintenance
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 3 152.
All of the recommended viscosity
grades are suitable for high ambient
temperatures.
Coolant and antifreeze
Use only silicate-free 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 frostprotection down to approx. -28 °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 fluid Only use DOT4+ brake fluid approved for the vehicle, consult a workshop.
Over time, brake fluid absorbs
moisture which will reduce braking
effectiveness. The brake fluid should
therefore be replaced at the specified interval.
Brake fluid should be stored in a
sealed container to avoid water
absorption.
Ensure brake fluid does not become contaminated.
