236 Driving and Operating
Average driver reaction time is
about three-quarters of a
second. In that time, a vehicle
moving at 100 km/h (60 mph)
travels 20 m (66 ft), which
could be a lot of distance in an
emergency.
Helpful braking tips to keep in
mind include:
.Keep enough distance
between you and the vehicle
in front of you.
.Avoid needless heavy
braking.
.Keep pace with traffic.
If the engine ever stops or a
brake fault occurs, the brakes
may lose power assist. More
effort will be required to stop
the vehicle and it can take
longer to stop.
Steering
Caution
To avoid damage to the
steering system, do not
drive over curbs, parking
barriers, or similar objects at
speeds greater than 3 km/h
(1 mph). Use care when
driving over other objects
such as lane dividers and
speed bumps. Damage
caused by misuse of the
vehicle is not covered by the
vehicle warranty.
Electric Power Steering
The vehicle is equipped with
an electric power steering
system, which reduces the
amount of effort needed to
steer the vehicle. It does not
have power steering fluid.
Regular maintenance is not
required.
If the vehicle experiences a
system malfunction and loses
power steering, greater
steering effort may be
required. Power steering
assist also may be reduced if
you turn the steering wheel as
far as it can turn and hold it
there with force for an
extended period of time.
See your dealer if there is a
problem.
Curve Tips
.Take curves at a reasonable
speed.
.Reduce speed before
entering a curve.

460 Vehicle Care
Steering, Suspension, and
Chassis Components
Visually inspect steering,
suspension, and chassis
components for damaged,
loose, or missing parts or signs
of wear at least once a year.
Inspect power steering for
proper attachment,
connections, binding, leaks,
cracks, chafing, etc.
Visually check constant
velocity joint boots and axle
seals for leaks.
Body Component
Lubrication
Lubricate all key lock cylinders,
hood hinges, liftgate hinges,
and the steel fuel door hinges,
unless the components are
plastic. Applying silicone
grease on weatherstrips with
a clean cloth will make them
last longer, seal better, and
not stick or squeak.
Underbody Maintenance
Every six months, use plain
water to flush any corrosive
materials from the underbody.
Take care to thoroughly clean
any areas where mud and
other debris can collect.
Do not directly power wash
the transfer case and/or
front/rear axle output seals.
High pressure water can
overcome the seals and
contaminate the fluid.
Contaminated fluid will
decrease the life of the
transfer case and/or axles and
should be replaced.
Sheet Metal Damage
If the vehicle is damaged and
requires sheet metal repair or
replacement, make sure the
body repair shop applies
anti-corrosion material to
parts repaired or replaced to
restore corrosion protection.Original manufacturer
replacement parts will provide
the corrosion protection while
maintaining the vehicle
warranty.
Finish Damage
Quickly repair minor chips and
scratches with touch-up
materials available from your
dealer to avoid corrosion.
Larger areas of finish damage
can be corrected in your
dealer's body and paint shop.
Chemical Paint Spotting
Airborne pollutants can fall
upon and attack painted
vehicle surfaces causing
blotchy, ring-shaped
discolorations, and small,
irregular dark spots etched
into the paint surface. See
“Finish Care”
previously in this
section.
