1. Park your vehicle on a level surface.
2. Look at the brake fluid reservoir to see
where the brake fluid level is relative
to the MIN and the MAX marks on the
reservoir.
Note: To avoid fluid contamination, the
reservoir cap must remain in place and fully
tight, unless you are adding fluid.
Only use fluid that meets our
specifications. See Capacities and
Specifications (page 344).

TROUBLESHOOTING
BRAKES – WARNING LAMPS If the ABS indicator illuminates
when you are driving, this
indicates a malfunction. Your
vehicle continues to have normal braking
without the anti-lock braking system
function. See an authorized dealer.
It also momentarily illuminates when you
switch the ignition on to confirm the lamp
is functional. If it does not illuminate when
you switch the ignition on, or begins to
flash at any time, have the system checked
by an authorized dealer. The brake indicator momentarily
illuminates when you switch the
ignition on to confirm the lamp
is functional. It may also illuminate when
you apply the parking brake and the
ignition is on. If it illuminates when your
vehicle is moving, make sure the parking
brake is disengaged. If the parking brake
is disengaged, this indicates low brake fluid
level or a brake system fault. See an
authorized dealer.
BRAKES – FREQUENTLY ASKED
QUESTIONS
Is occasional brake noise normal
Occasional brake noise is normal. If a
metal-to-metal, continuous grinding
or continuous squeal sound is present,
the brake linings could be worn-out.
Have the system checked by an
authorized dealer.

PARKING AID PRECAUTIONS
WARNING: To help avoid personal
injury, always use caution when in
reverse (R) and when using the sensing
system. WARNING:
The system may not
detect objects with surfaces that absorb
reflection. Always drive with due care
and attention. Failure to take care may
result in a crash. WARNING: Traffic control systems,
fluorescent lamps, inclement weather,
air brakes, external motors and fans may
affect the correct operation of the
sensing system. This may cause reduced
performance or false alerts. WARNING:
The system may not
detect small or moving objects,
particularly those close to the ground. WARNING:
The parking aid system
can only assist you to detect objects
when your vehicle is moving at parking
speeds. To help avoid personal injury you
must take care when using the parking
aid system. WARNING:
The system may not
function if the sensor is blocked. WARNING:
In cold and severe
weather conditions the system may not
function. Rain, snow and spray can all
limit sensor performance. WARNING:
If damage occurs in the
immediate area surrounding the sensor,
have your vehicle checked as soon as
possible. Note:
If your vehicle sustains damage
leaving the sensors misaligned, this will
cause inaccurate measurements or false
alerts.
When you connect a trailer to your vehicle,
the rear parking aid detects the trailer and
provides an alert. Disable the parking aid
when you connect a trailer to prevent the
alert.
Note: Certain add-on devices installed
around the bumper or fascia may create
false alerts, for example, large trailer
hitches, bike or surfboard racks, license plate
brackets, bumper covers or any other device
that could block the normal detection zone
of the parking aid system. Aftermarket spare
tires or spare tire covers mounted to the rear
tailgate could cause false alerts from the
park aid system. Remove the add-on device
to prevent false alerts.
Note: Keep the sensors free from snow, ice
and large accumulations of dirt. If the
sensors are covered, the system's accuracy
can be affected.
Do not clean the sensors with sharp
objects.
Note: When using a programmed MyKey
you cannot switch this off. See
MyKey ™
(page 73).
SWITCHING PARKING AID ON
AND OFF Press the parking aid button and
use the menu to turn the system
on and off.
The system can also be turned off using
the pop-up message that appears when
you are in reverse (R).
