Before DrivingDriving PreparationCheck the following items before you start driving.
•Make sure there are no obstructions on the windows, door mirrors, exterior
lights, or other parts of the vehicle.
u Remove any frost, snow, or ice.
u Remove any snow on the roof, as this can slip down and obstruct your field of
vision while driving. If frozen solid, remove ice once it has softened.
u When removing ice from around the wheels, be sure not to damage the wheel
or wheel components.
• Make sure the hood is securely closed.
u If the hood opens while driving, your front view will be blocked.
• Make sure the tires are in good condition.
u Check air pressure, check for damage and excessive wear.
2 Checking and Maintaining Tires P. 259
•Make sure there are no people or objects behind or around the vehicle.
u There are blind spots from the inside.■
Exterior Checks
1Exterior Checks
NOTICEWhen doors are frozen shut, use warm water around
the door edges to melt any ice. Do not try to force
them open, as this can damage the rubber trim
around the doors. When done, wipe dry to avoid
further freezing.
Do not pour warm water into the key cylinder.
You will be unable to insert key if the water freezes in
the hole.
Heat from the engine and exhaust can ignite
flammable materials left under the hood, causing a
fire. If you’ve parked your vehicle for an extended
period, inspect and remove any debris that may have
collected, such as dried grass and leaves that have
fallen or have been carried in for use as a nest by a
small animal. Also check under the hood for leftover
flammable materials after you or someone else has
performed maintenance on your vehicle.

Driving
Towing a TrailerTowing PreparationYour vehicle can tow a trailer if you carefully observe the load limits, use the proper
equipment, and follow the towing guidelines. Check the load limits before driving.
■
Total trailer weight
Maximum allowable weight of the trailer,
cargo, and everything in or on it must not
exceed 1,000 lbs (450 kg). Towing loads in
excess of this can seriously affect vehicle
handling and performance and can damage
the engine and drivetrain.
■
Tongue load
The weight of the tongue with a fully loaded
trailer on the hitch should be approximately
10% of the total trailer weight.
• Excessive tongue load reduces front tire
traction and steering control. Too little
tongue load can make the trailer unstable
and cause it to sway.
• To achieve a proper tongue load, start by
loading 60% of the load toward the front
of the trailer and 40% toward the rear.
Readjust the load as needed.
■
Towing Load Limits
1Towing Load Limits
Check if all loads are within limits at a public scale.
If a public scale is not available, add the estimated
weight of your cargo load to the weight of your
trailer (as quoted by the manufacturer), and the
tongue load.
Break-in Period
Avoid towing a trailer during your vehicle’s first 600
miles (1,000 km).
Never exceed the gross weight ratings.

WARNING
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 before starting to drive.

electrical accessories such as the lights, climate
control system, and rear defogger in order to reduce
battery drain.
If you live in a region where winter is extremely cold,
an engine block heater will improve starting and
warming of the engine. If temperatures consistently
below -22°F (-30°C) are expected, the coolant
mixture should be changed to a higher concentration
to prevent freezing. Consult a dealer for details.
If exhaust sounds abnormal or you can smell exhaust
gas inside the vehicle, have your vehicle checked by a
dealer. There may be a problem with the engine or

uuWhen Driving uVSA ® (Vehicle Stability Assist), aka ESC (Electronic Stability Control), System
Driving
VSA ® (Vehicle Stability Assist), aka ESC (Electronic Stability Control), SystemVSA ® helps to stabilize the vehicle during cornering if the vehicle turns more or less
than what was intended. It also assists in maintaining traction on slippery surfaces.
It does so by regulating engine output and selectively applying the brakes.
When VSA® activates, you may notice that the
engine does not respond to the accelerator.
You may also notice some noise from the
hydraulic system. You will also see the
indicator blink.■
VSA ® Operation
1 VSA ® (Vehicle Stability Assist), aka ESC (Electronic Stability Control), System
The VSA ® may not function properly if tire type and
size are mixed. Make sure to use the same size and
type of tire, and the ai r pressures as specified.
When the VSA ® indicator comes on and stays on
while driving, there may be a problem with the
system. While this may not interfere with normal
driving, have your vehicle checked by a dealer
immediately.
VSA ® cannot enhance stability in all driving situations
and does not control the entire braking system. You
still need to drive and cor ner at speeds appropriate
for the conditions and always leave a sufficient
margin of safety.
The main function of the VSA ® system is generally
known as Electronic Stability Control (ESC). The
system also includes a traction control function.

This button is on the driver side control panel.
To turn the VSA ® system on and off, press and
hold it until you hear a beep.
VSA ® will stop and the indicator will come on.
To turn it on again, press the (VSA ® OFF)
button until you hear a beep.
VSA ® is turned on every time you start the
engine, even if you turned it off the last time
you drove the vehicle.
■
VSA ® On and Off
1 VSA ® (Vehicle Stability Assist), aka ESC (Electronic Stability Control), System
Without VSA ®, your vehicle will have normal braking
and cornering ability, but it will not have VSA ®
traction and stability enhancement.
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. You should only attempt to 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 VSA® on again. We do not recommend driving
your vehicle with the VSA ® and traction control
systems switched off.
If the low tire pressure/TPMS indicator comes on or
blinks, the VSA ® system comes on automatically. In
this case, you cannot turn the system off by pressing
the button.
You may hear a motor sound coming from the
engine compartment while system checks are being
performed immediatel y after starting the engine or
while driving. This is normal.

uuBraking uBrake System
Driving
Your vehicle is equipped with disc brakes at all four wheels. A vacuum power assist
helps reduce the effort needed on the brake pedal. The brake assist system increases
the stopping force 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.

Foot Brake
1Foot Brake
Check the brakes after driving through deep water,
or if there is a buildup of road surface water. If
necessary, dry the brakes by lightly depressing the
pedal several times.
If you hear a continuous metallic friction sound when
applying the brakes, the brake pads need to be
replaced. Have the vehicle checked by a dealer.
Constantly using the brake pedal while going down a
long hill builds up heat, which reduces the brake
effectiveness. Apply engine braking by taking your
foot off the accelerator pedal and downshifting to a
lower gear. With manual transmission use a lower
gear for greater engine braking.
Do not rest your foot on the brake pedal while
driving, as it will lightly apply the brakes and cause
them to lose effectiveness over time and reduce pad
life. It will also confuse drivers behind you.
