Your vehicle is equipped with a tire
pressure monitoring system (TPMS)
that turns on every time you start the
engine and monitors the pressure in
your tires while driving.
Each tire has its own pressure
sensor. If the air pressure of a tire
becomes signif icantly low, the
sensor in that tire immediately sends
a signal that causes the low tire
pressure/TPMS indicator in the
instrument panel to come on. If this
happens, you will see which tire is
losing pressure on the multi-
inf ormation display along with a
‘‘CHECK TIRE PRESSURE’’
message.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 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 ).
Driving on a signif icantly under-
inf lated tire causes the tire to
overheat and can lead to tire failure.
Under-inf lation also reduces f uel
efficiency and tire tread life, and may
af f ect the vehicle’s handling and
stopping ability.
Becausetirepressurevariesby
temperature and other conditions,
the low tire pressure/TPMS
indicator may come on unexpectedly.
When the low tire pressure/TPMS
indicator is on, one or more of your
tires is signif icantly underinf lated.
Youshouldstopandcheckyourtires
as soon as possible, and inflate them
to the proper pressure as indicated
on the vehicle’s tire inf ormation
placard.
It is possible that the pressures
shown on the multi-inf ormation
display and the pressures you
manually measure are slightly
dif f erent.
If the dif f erence is signif icant or you
cannot make the low tire pressure/
TPMS indicator and message on the
multi-inf ormation display go out af ter
inf lating the tires to the specif ied
values, have your dealer check the
system as soon as possible.

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.
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 emergency
brake assist system increases the
stopping f orce when you depress the
brake pedal hard in an emergency
situation. The anti-lock brake system
(ABS) helps you retain steering
control when braking very hard.
Resting your f oot on the pedal keeps
the brakes applied lightly, builds up
heat, and reduces their ef f ectiveness
and reduces brake pad life. In
addition, f uel economy can be
reduced. It also keeps your brake
lights on all the time, conf using
drivers behind you.As required by the FCC:
This device complies with Part 15 of theFCC rules. Operation is subject to thef ollowing two conditions: (1) This devicemay not cause harmf ul interf erence, and(2) this device must accept anyinterf erence received, includinginterf erence that may cause undesiredoperation.Changes or modif ications not expresslyapproved by the party responsible f orcompliance could void the user’sauthority to operate the equipment.This device complies with IndustryCanada Standard RSS-210.Operation is subject to the f ollowing twoconditions: (1) this device may not causeinterf erence, and (2) this device mustaccept any interf erence that may causeundesired operation of the device.

The vehicle stability assist (VSA)
system helps to stabilize the vehicle
during cornering if the vehicle turns
more or less than desired. It also
assists you in maintaining traction
while accelerating on loose or
slippery road surf aces. It does this
by regulating the engine’s output and
by selectively applying the brakes.
When VSA activates, you may notice
that the engine does not respond to
the accelerator in the same way it
does at other times. There may also
be some noise f rom the VSA
hydraulic system. You will also see
the VSA activation indicator blink.
The VSA system cannot enhance the
vehicle’s driving stability in all
situations and does not control your
vehicle’s entire braking system. It is
still your responsibility to drive and
corner at reasonable speeds and to
leave a sufficient margin of safety.When VSA activates, you will see the
VSA activation indicator blink.
If this indicator comes on while
driving, pull to the side of the road
when it is saf e, and turn of f the
engine. Reset the system by
restarting the engine. If the VSA
system indicator stays on or comes
back on while driving, have the VSA
system inspected by your dealer.
If the indicator does not come on
when the ignition switch is turned to
the ON (II) position, there may be a
problem with the VSA system. Have
your dealer inspect your vehicle as
soon as possible.
You will also see a ‘‘CHECK VSA
SYSTEM’’ message on the multi-
inf ormation display if there is a
problem with the VSA system.
If the low tire pressure/TPMS
indicator comes on, or the multi-
inf ormation display shows a
‘‘CHECK TPMS SYSTEM’’ message,
the VSA system automatically turns
on even when the VSA system is
turned of f by pressing the VSA OFF
switch (see page ). If this
happens, you cannot turn the VSA
system of f by pressing the VSA OFF
switch again.
Without VSA, your vehicle will have
normal braking and cornering ability,
but it will not have VSA traction and
stability enhancement.

Under these conditions, trailer
stability assist begins to stabilize the
vehicle/trailer combination by
reducing the vehicle speed. The
control unit sends signals to
selectively apply the brakes and
regulate the engine output. The
brake lights of your vehicle will be
turned on automatically by the
system even if you do not keep the
pressure on the brake pedal.
Your vehicle is equipped with trailer
stability assist f unction. This
f unction works on the same sensors
as the vehicle stability assist (VSA)
system. This f unction helps to
stabilize the vehicle/trailer
combination when the trailer
severely sways or oscillates. For
more inf ormation of the VSA system,
see page .
When the brakes are applied, the
trailer’s brake lights come on along
with the vehicle brake lights.
When the trailer stability assist
activates, you will see the VSA
activation indicator blink. There may
also be some noise f rom the VSA
hydraulic system.Trailer stability assist cannot prevent
a loss of control. Always reduce the
vehicle speed and steer f irmly. Do
not brake suddenly or make quick
steering motion. It could cause the
trailertojackknifeorturnoverand
the system becomes inef f ective.
Trailer stability assist cannot prevent
swaying that can occur in crosswinds
and in normal and emergency
driving maneuvers. It helps only to
stabilize the vehicle/trailer
combination in these conditions,
af ter the oscillation becomes severe.
If the function detects the vehicle/
trailer instability, it checks if the
swaying is caused by the trailer, and
if the trailer swaying or oscillation is
increasing.
The vehicle/trailer combination is
more af f ected by crosswinds,
buf f eting, and improper tongue load.
These conditions can make the
trailer unstable, and cause it to sway. Always obey the recommended
speed limits f or towing a trailer, see
page .
Trailer stability assist will also be
inef f ective while driving at high
speed or towing a trailer with a high
center of gravity.

Press and hold the VSA of f switch
until you hear a beep (see page ).
The VSA activation indicator comes
on as a reminder. Press and hold the
switch again to turn the system on.
The function turns on every time you
start the engine along with the VSA,
even if you turned it of f the last time
you drove the vehicle.
The control unit monitors the VSA
circuitry and the braking system. If
there is a problem with the brake
lighting system, the trailer stability
assist f unction shuts down and the
‘‘CHECK TRAILER STABILITY
ASSIST’’ message appears on the
multi-inf ormation display.
If you see this message, have your
vehicle checked at your dealer as
soon as possible. In this case, your vehicle still has the
VSA traction and stability
enhancement, but it will not have the
trailer stability assist f unction.
If there is a problem with the VSA
system, the system and Trailer
Stability Assist shuts of f . The VSA
system and VSA activation indicators
also come on (see page ).
The ABS indicator and the brake
system indicator may also come on
along with the VSA system indicator.
If you see these warning indicators,
have your vehicle checked at your
dealer as soon as possible.

Before you leave the pavement, be
sure to do all scheduled maintenance
and service, and inspect your vehicle
f or any problems. Pay special
attention to the condition of the tires,
and check the tire pressures.
After you return to the pavement,
caref ully inspect your vehicle to
make sure there is no damage that
could make driving it unsaf e.
Recheck the condition of the tires
and the tire pressures.
The route presents limits (too steep
or bumpy roads). You have limits
(driving skill and comfort). And your
vehicle has limits (traction, stability,
and power).
Driving of f -highway can be
hazardous if you f ail to recognize
limits and take the proper
precautions.Forbettertractiononallsurfaces,
accelerate slowly and gradually build
up speed. If you try to start too fast
on wet soil, mud, snow, or ice, you
might not have enough traction to
get underway, and you may dig
yourself a hole. Starting with the
shif t lever in D position will help you
have a smoother start on snow or ice.
Keep in mind that you will usually
need more time and distance to
brake to a stop on unpaved surf aces.
Avoid hard braking. Do not ‘‘pump’’
the brakes; let the anti-lock braking
system pump them f or you.
Debris in the road can damage your
suspension or other components.
Because your vehicle has a high
center of gravity, driving over a large
obstacle, or allowing a wheel to drop
into a deep hole can cause your
vehicle to tip or roll over.If you can’t clearly see all conditions
or obstacles on a slope, walk the
slope bef ore you drive on it. If you
have any doubt whether or not you
can saf ely drive on the slope, don’t
do it. Find another route.
If you are driving up a hill and f ind
that you cannot continue,
. Your vehicle could roll
over. Slowly back down the hill,
f ollowing the same route you took up
the hill.
Bef ore driving through water, stop,
get out if necessary, and make sure
that: The water is not deep enough to
cover your wheel hubs, axles, or
exhaust pipe. You could stall and
not be able to restart your engine.
The water can also damage
important vehicle components.
do not try to
turn around
