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.
Resting your f oot on the brake pedal
applies the brakes slightly. This
builds up heat, and reduces brake
ef f ectiveness and brake pad lif e. In
addition, f uel economy can be
reduced. It also keeps your brake
lights on all the time, conf using driver’s behind you. Constant
application of the brakes when going
down a long hill builds up heat and
reduces their effectiveness. Use the
engine to assist the brakes by taking
your foot off the accelerator and
downshifting to a lower gear. 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 f ront
disc brakes. The brakes on the rear
wheels may be disc or drum,
depending on the model. A power
assist helps reduce the ef f ort needed
on the brake pedal. The ABS helps
you retain steering control when
braking very hard.

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 surfaces. 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 unusual noise from the
modulator. You will also see the VSA
activation indicator blink.
The VSA system cannot enhance the
vehicle’s driving stability in all
situ ations 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 blinks.
If this indicator comes on while
driving, pull to the side of the road
when it is safe, and turn off 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 deale r. 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 (see page ).
Without VSA, your vehicle will have
normal braking and cornering ability,
but it will not have VSA traction and
stability enhancement. 62

This switch is under the left vent.
Press it to turn the VSA system on
and off.
When VSA is off, the VSA activation
indicator comes on as a reminder. In
certain unusual conditions when
your vehicle gets stuck in shallow
mud or fresh snow, it may be easier
to free it with the VSA temporarily
switched off. When the VSA system
is off, the traction control system is
also off.Youshouldonlyattemptto
free your vehicle with the VSA off if
you are not able to free it when the
VSA is on.
Immediately after freeing your
vehicle, be sure to switch the VSA on
again. We do not recommend driving
your vehicle with the VSA and
traction control systems switched off.
VSA is turned on every time you
start the engine, even if you turn ed it
off the last time you drove the
vehicle. 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 ).
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. 250

Your vehicle has been designed
primarily to 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
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. Theweightthatthe
tongue of a f ully-loaded trailer puts
on the hitch should be approximately
10 % of the total trailer weight. Too
much tongue load reduces f ront-tire
traction and steering control. Too
little tongue load can make the
trailer unstable and cause it to sway.

Exceeding any load limit or
improperly loading your vehicle
and trailer can cause a crash in
which you can be seriously hurt
or killed.
Check the loading of your
vehicle and trailer carefully
beforestartingtodrive.

The added weight, length, and
height of a trailer will af f ect your
vehicle’s handling and perf ormance,
so driving with a trailer requires
some special driving skills and
techniques.

If you have an automatic

Your vehicle displays engine oil life
and maintenance service items on
the information display to show you
when you should have your dealer
perform engine oil replacement and
indicated maintenance service.
Based on the engine operating
conditions and accumulated engine
revolutions, the onboard computer in
your vehicle calculates the remaining
engine oil life and displays it as a
percentage.
To see the current engine oil life,
turn the ignition switch to the ON
(II) position, and press the SEL/
RESET button repeatedly until the
engine oil lif e display appears (see
