The Active differential control (E-diff) improves
traction on uneven road surfaces and can also
improve stability in oversteer situations.

be automatically selected. The vehicle can still
be driven and DSC mode s can be selected, but
seek qualified assistan ce as soon as possible.
If the warning message EDIFF NOT AVAILABLE
is displayed, the system has temporarily shut

Fluid level checks
171
If the message LOW COOLANT LEVEL is
displayed in the message centre, stop the
vehicle as soon as safe ty permits and top-up
the coolant reservoir with the recommended
antifreeze/water mix.
If the message centre displays the message
ENGINE OVERHEATING, pull off the
carriageway and allow the e ngine to idle for five
minutes and then switch off the ignition for ten
minutes. Switch on the engine and, provided
that the warning does not occur, continue your
journey, avoiding hars h acceleration. Seek
qualified assistance as soon as possible.
TOPPING UP THE COOLANT
Never remove the filler cap when the
engine is hot.
Antifreeze is highly inflammable. Do
not allow antifreeze to come into
contact with naked flames or other
sources of ignition (e.g. a hot engine)
- a fire may result.
Unscrew the filler cap slowly,
allowing the pressure to escape
before removing completely.
When travelling in territories where the
water supply contains salt, always
ensure you carry a supply of fresh (rain
or distilled) water. Topping up with salt
water will cause serious engine
damage.
Top-up to the upper le vel indicator mark
located on the side of the expansion tank. Use
only a 50% mix of water and antifreeze to
specification WSS M97B44 (coloured orange)
Extended Life Coolant.
Ensure the cap is tightened fully after top-up is
completed by turning the cap until the ratchet
cap clicks. Note:
In an emergency, if the approved
antifreeze is unavailable, top-up the system
with clean water, but be aware of the resultant
reduction in frost protection. Do not top-up or
refill with conventional an tifreeze formulations.
If in doubt consult a qualified technician.
BRAKE FLUID CHECK
Seek qualified assistance
immediately if brak e pedal travel is
unusually long, unusua lly short or if
there is any signific ant loss of brake
fluid. Driving under such conditions
could result in extended stopping
distances or complete brake failure.
Note: If the warning lamp illuminates or the
message is displayed while the vehicle is being
driven, stop the vehicle as soon as safety
permits by gently appl ying the brakes. Check
and top-up the fluid level if necessary.
Brake fluid is highly toxic - keep
containers sealed and out of the reach
of children. If accidental consumption
is suspected, seek medical attention
immediately.
If the fluid comes into contact with the
skin or eyes, rins e immediately with
plenty of water.
Brake fluid is highly inflammable. Do
not allow brake fluid to come into
contact with naked flames or other
sources of ignition (e.g. a hot engine).
If the quantity of fluid in the brake
reservoir drops below the
recommended level, a red warning
lamp in the inst rument panel will
illuminate and the message Brake
Fluid Low will be displayed in the
message centre.
