If the SH-AWD indicator blinks while
driving, it indicates the dif f erential
temperature is too high. You will also
see an ‘‘SH-AWD DIFF TEMP.
HIGH’’ message on the multi-
inf ormation display. If this happens,
pull to the side of the road when it is
saf e, shif t to Park, and let the engine
idle until the indicator goes out. If
the indicator does not go out, take
your vehicle to a dealer to have it
checked.If the SH-AWD indicator on the
instrument panel stays on, and the
‘‘CHECK SH-AWD SYSTEM’’
message also appears on the multi-
inf ormation display, there is a
problem with the SH-AWD system.
Your vehicle still has normal f ront-
wheel drive with vehicle stability
assist (VSA), but does not have the
advantages of SH-AWD. Have your
vehicle checked by a dealer as soon
as possible.

Always use the parking brake when
you park your vehicle. Make sure
the parking brake is set f irmly or
your vehicle may roll if it is on an
incline.
Set the parking brake bef ore you put
the transmission in Park. This keeps
the vehicle from moving and putting
pressure on the parking mechanism
in the transmission.Make sure the moonroof and the
windows are closed.
Turn of f the lights.
Place any packages, valuables, etc.,
in the trunk or take them with you.
Lock the doors.
Never park over dry leaves, tall
grass, or other f lammable
materials. The hot three way
catalytic converter could cause
these materials to catch on fire.
If the vehicle is f acing uphill, turn
the f ront wheels away f rom the
curb.
If the vehicle is f acing downhill,
turn the front wheels toward the
curb.Check the indicator on the
instrument panel to verif y that the
security system is set.
Make sure the parking brake is
f ully released bef ore driving away.

Your vehicle is equipped with disc
brakes at all f our wheels. A power
assist helps reduce the ef f ort needed
on the brake pedal. The brake pedal
assist f unction increases the f orce
you apply to the brake pedal during
an emergency stop. When the brake
pedal assist is activated, the e-
pretensioners (if equipped) tighten
f ront seat belts (see page ). The
anti-lock brake system (ABS) helps
you retain steering control when
braking very hard (see page ).
Resting your f oot on the pedal keeps
the brakes applied lightly, builds up
heat, reduces their ef f ectiveness and
reduces brake pad lif e. In addition,
f uel economy can be reduced. It also
keeps your brake lights on all the
time, conf using drivers behind you.The hydraulic system that operates
the brakes has two separate circuits.
Each circuit works diagonally across
the vehicle (the lef t-f ront brake is
connected with the right-rear brake,
etc.). If one circuit should develop a
problem, you will still have braking
at two wheels. Constant application of the brakes
when going down a long hill builds
up heat and reduces their ef f ective-
ness. Use the engine to assist the
brakes by taking your f oot of f the
accelerator and downshif ting to a
lower gear.
Check the brakes after driving
through deep water. Apply the
brakes moderately to see if they f eel
normal. If not, apply them gently and
f requently until they do. Be extra
cautious in your driving.If the brake pads need replacing, you
will hear a distinctive, metallic
screeching sound when you apply
the brake pedal. If you do not have
the brake pads replaced, they will
screech all the time. It is normal f or
the brakes to occasionally squeal or
squeak when you apply them. 24

The anti-lock brake system (ABS)

locking up, and helps you retain
steering control by pumping the
brakes rapidly, much f aster than a
person can do it.If this indicator comes on, the anti-
lock f unction of the braking system
has shut down. The brakes still work
like a conventional system, but
without anti-lock. You should have
your dealer inspect your vehicle as
soon as possible. You will f eel a pulsation in the brake
pedal when the ABS activates, and
you may hear some noise. This is
normal: it is the ABS rapidly

pavement, you will need to press on
thebrakepedalveryhardbeforethe
ABS activates. However, you may
feel the ABS activate immediately if
you are trying to stop on snow or ice.
Let the ABS work f or you by always
keeping f irm, steady pressure on the
brake pedal. This is sometimes
ref erred to as ‘‘stomp and steer.’’ The electronic brake distribution
(EBD) system, which is part of the
ABS, also balances the f ront-to-rear
braking distribution according to
vehicle loading.When the ABS indicator comes on,
you will also see a ‘‘CHECK ABS
SYSTEM’’ message on the multi-
inf ormation display.
If the ABS indicator comes on while
driving, test the brakes as shown on
page .510
You should never pump the brake pedal.

lane change. Always drive at a safe
speed f or the road and weather
conditions.
Always steer moderately
when you are braking hard. Severe
or sharp steering wheel movement
can still cause your vehicle to veer
into oncoming traffic or off the road. If the ABS indicator and the brake
system indicator come on together,
and the parking brake is f ully
released, the EBD system may also
be shut down.
Test your brakes as instructed on
page . If the brakes f eel normal,
drive slowly and have your vehicle
repaired by your dealer as soon as
possible. Avoid sudden hard braking
which could cause the rear wheels to
lock up and possibly lead to a loss of
control.510A vehicle with A BS may require a

A BS does not reduce the time or
distance it takes to stop the
vehicle.

Although your tire pressure is
monitored, you must manually check
thetirepressuresmonthly.
Each tire, including the spare, should
be checked monthly when the
vehicle is cold, and set to the
recommended inf lation pressure as
specif ied on the vehicle placard and
intheowner’smanual(seepage
).
If the tire is f lat, or if the tire
pressure is too low to continue
driving, replace the tire with the
compact spare tire (see page ). If you think you can saf ely drive a
short distance to a service station,
proceed slowly to the station, then
inflate the tire to the recommended
pressure.If you have a f lat tire, the low tire
pressure/TPMS and tire monitor
indicators will come on. Replace the
indicated f lat tire with the compact
sparetire(seepage ).
After the flat tire is replaced with the
spare tire, the low tire pressure/
TPMS indicator stays on while
driving. Af ter several miles
(kilometers) driving, this indicator
begins to f lash, then stays on again.
You will also see a ‘‘CHECK TPMS
SYSTEM’’ message on the multi-
inf ormation display. This is normal;
the system cannot monitor the spare
tire pressure. Manually check the
