Brake functions
The vehicle's standard braking features are aug-
mented by a number of auxiliary help functions.
In addition to the wheel brakes and the parking
brake, the vehicle is equipped with several auto-
matic brake assist functions. These systems help
the driver by e.g., keeping the vehicle stationary
when the brake pedal is not depressed (at a traf-
fic light or intersection), when starting up a hill or
when driving down a hill.
These systems include:
•
Auto-hold brakes
•
Hill Start Assist
•
Braking assist after a collision

Brakes
The brake system is a hydraulic system consist-
ing of two separate brake circuits. If a problem
should occur in one of these circuits, it is still
possible to stop the vehicle with the other brake
circuit.
Brake system
If one of the brake circuits is not functioning,
more pressure will be needed on the brake pedal
(and the pedal will go down farther) for normal
braking effect.
If the brake pedal must be depressed farther
than normal and requires greater foot pressure,
the stopping distance will be longer.
Pressure on the brake pedal is enhanced by the
power braking function.
The power brakes only function when the engine
is running.
If the power brakes are not working, considerably
higher pressure will be required on the brake
pedal to compensate for the lack of power assis-
tance. This can happen for example when towing
your vehicle or if the engine is switched off when
the vehicle is rolling. The brake pedal feels stiffer
than usual.
When the Hill Start Assist function is being used,
it will take slightly longer for the brake pedal to
return to its normal position if the vehicle is
parked on an incline or uneven surface.
When driving in very hilly areas or if the vehicle is
carrying a heavy load, manual gear shifting can
be used for engine braking to augment the
brakes.
Hill Descent Control can also be used
on steep downgrades to increase the engine
braking effect at low speeds.
When driving in very hilly areas or if the vehicle is
carrying a heavy load, manual gear shifting can
be used for engine braking to augment the
brakes.
Anti-lock Braking System (ABS)
The ABS system helps to improve vehicle control
(stopping and steering) during severe braking
conditions by limiting brake lockup.
When ABS is operating, there may be some
vibration in the brake pedal, which is normal.
The system performs a brief self-diagnostic test
when the engine has been started and driver
releases the brake pedal. Another automatic test
may be performed when the vehicle first reaches
a speed of approximately 6 mph (10 km/h). The
brake pedal will pulsate several times and a
sound may be audible from the ABS control
module, which is normal.
Cleaning the brake discs
Coatings of dirt and water on the brake discs
may result in delayed brake function. This delay is
minimized by cleaning the brake linings.
Cleaning the brake pads is advisable in wet
weather, prior to long-term parking, and after the
