Disc brakes wear indicator
When your brake pads are worn and new
pads are required, you will hear a high
pitched warning sound from your front
or rear brakes. You may hear this sound
come and go or it may occur whenever
you depress the brake pedal.
Note that some driving conditions or
climates may cause a brake squeal
when you first apply (or lightly apply)
the brakes. This is normal and does not
indicate a problem with your brakes.
NOTICE
To avoid costly brake repairs, do not
continue to drive with worn brake pads.
Information
Always replace brake pads as complete
front or rear axle sets.

Additional driving conditions
• Become familiar with the off-road
conditions before driving.
• Always pay attention when driving off-
road and avoid dangerous areas.
• Drive slowly when driving in heavy
wind.
• Reduce vehicle speed when
cornering. The center of gravity
of AWD vehicles is higher than
conventional 2WD vehicles, making
them more likely to roll over when you
rapidly turn corners.
• Always hold the steering wheel firmly
when you are driving off-road.
WARNING
Do hold the steering wheel tightly
when you are driving off-road. You may
hurt your arm by a sudden steering
maneuver or from steering wheel
rebound due to an impact with objects
on the ground. You could lose control
of the steering wheel which may lead to
serious injury or death.
Emergency precautions
Tires
When replacing tires, be sure to equip
all four tires with the same size, type,
tread patterns, brand and load-carrying
capacity.
WARNING
Do not use tire and wheel with different
size and type from the one originally
installed on your vehicle. It can affect
the safety and performance of your
vehicle, which could lead to steering
failure or rollover causing serious injury.
In an emergency situation, a compact
spare tire (if equipped) or Tire Mobility
Kit (if equipped) may be used. But,
do not use the compact spare tire
continuously. Repair or replace the
original tire as soon as possible to avoid
failure of the differential or AWD system.
WARNING
Never start or run the engine while
an AWD vehicle is raised on a jack.
The vehicle can slip or roll off of a jack
causing serious injury or death to you or
those nearby.
