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.
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.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.
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. Emergency
Brake Assist System gains the
stopping f orce when you depressed
thebrakepedalhardinanemergent
situation. The anti-lock brake system
(ABS) helps you retain steering
control when braking very hard.
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. Resting your f oot on the pedal keeps
the brakes applied lightly, builds up
heat, and reduces their ef f ectiveness.
It also keeps your brake lights on all
the time, conf using drivers behind
you. Braking System Design

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 indicator in the
instrumental panel and the
appropriate tire position indicator on
thetirepressuremonitoronthe
multi-inf ormation display (see page)tocomeon. For example, if you check and f ill
your tires in a warm area, then drive
in extremely cold weather, the tire
pressure will be lower than
measured and could be underinflated
and cause the low tire pressure
indicator to come on. Or, if you
check and adjust your tire pressure
in cooler conditions, and drive into
extremely hot conditions, the tire
maybecomeoverinflated.However,
the low tire pressure indicator will
not come on if the tires are
overinf lated.
When the low tire pressure indicator
is on, one or more of your tires is
signif icantly underinf lated. The
multi-inf ormation display also shows
a ‘‘CHECK TIRE PRESSURE’’
message (see page ). You should
stop and check your tires as soon as
possible, and inflate them to the
proper pressure as indicated on the
vehicle’s tire inf ormation placard.
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 indicator may
come on unexpectedly.
Refer to page for tire inflation
guidelines.

Driving with varying tire or wheel
sizes may cause the VSA to
malf unction. When replacing tires,
make sure they are of the same size
and type as your original tires (see
page ).
Deactivate the VSA system if you
need to drive with the compact spare
tire installed (see page ).
If you install winter tires, make sure
they are the same size as those that
were originally supplied with your
vehicle. Exercise the same caution
during winter driving as you would if
your vehicle was not equipped with
VSA.
This switch is at the right side of the
lef t vent. Press it to turn VSA on and
off.
When VSA is off, the VSA activation
indicator comes on as a reminder.
VSA is turned on every time you
start the engine, even if you turned it
off the last time you drove the
vehicle.
When the VSA system indicator
comes on, you will also see a
‘‘CHECK VSA SYSTEM’’ message
on the multi-information display.
Without VSA, your vehicle still has
normal braking and cornering ability,
but it does not have VSA traction and
stability enhancement.
If the low tire pressure indicator
comes on (see page ), or the
multi-inf ormation display shows a
‘‘CHECK TPMS SYSTEM’’ message
(see page ), the VSA system
automatically turns on even when
the VSA system is turned of f with
the VSA OFF switch. In this case,
you cannot turn the VSA system of f
by pressing the VSA OFF switch
again.

Your vehicle has been designed to
primarily carry passengers and their
cargo. You can also use it to tow a
trailer if you caref ully observe the
load limits, use the proper equipment,
and f ollow the guidelines in this
section.The weight that
the tongue of a f ully-loaded trailer
puts on the hitch should be
approximately 10 percent of the
trailer weight. Too much tongue
load reduces front-tire traction and
steering control. Too little tongue
load can make the trailer unstable
and cause it to sway.
The
maximum allowable weight of the
trailer and everything in or on it
must not exceed 1,000 lbs (450 kg).
Towing a load that is too heavy
can seriously af f ect your vehicle’s
handling and perf ormance. It can
also damage the engine and
drivetrain.
