STARTING AND DRIVING
* Option/accessory. 384
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. Use the
Off Road
drive mode on steep
downgrades to increase the engine braking
effect at low speeds.
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
vehicle has been washed. Do this by braking gen-
tly for a short period while the vehicle is moving.
Driving on wet or salted roads
Prolonged driving on wet or salted roads can
affect brake function and increase stopping dis-
tance. Be sure to keep a safe distance to the
vehicle ahead when driving under these condi-
tions.
Brake pad inspection
On vehicles equipped with a jack
*
, the condition
of the brake pads can be checked by raising the
vehicle and performing a visual inspection of the
brake pads.
WARNING
•
If the vehicle has been driven immediately
prior to a brake pad inspection, the wheel
hub, brake components, etc., will be very
hot. Allow time for these components to
cool before carrying out the inspection.
•
Apply the parking brake and put the gear
selector in the Park (
P
) position.
•
Block the wheels standing on the ground,
use rigid wooden blocks or large stones.
WARNING
•
Use the jack intended for the vehicle
when changing a tire. For any other job,
use stands to support the vehicle.
•
The jack should be kept well-greased and
clean, and should not be damaged.
•
Be sure the jack is on a firm, level, non-
slippery surface.
•
No objects should be placed between the
base of jack and the ground, or between
the jack and the attachment bar on the
vehicle.
•
The jack must correctly engage the jack
attachment.
•
Never allow any part of your body to be
extended under a vehicle supported by a
jack.
