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. 421
•Make sure there are no people or objects behind or around the vehicle.
u There are blind spots from the inside.■
Exterior Checks
1Exterior ChecksNOTICEWhen 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 the 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.

When DrivingStarting the Engine
1.Make sure the parking brake is applied.
2. Check that the shift lever is in
(P
, then
depress the brake pedal.
u Although it is possible to start the vehicle
in
(N
, it is safer to start it in
(P
.
3. Press the ENGINE START/STOP button
without depressing the accelerator pedal.
The engine will crank until it starts.
1 Starting the Engine
Keep your foot firmly on the brake pedal when
starting the engine.
The engine is harder to start in cold weather and in
thinner air found at altitudes above 8,000 feet (2,400
meters).When starting the engine in cold weather, turn off all
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 the exhaust system 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 exhaust system.
Bring the keyless access remote close to the ENGINE
START/STOP button if the battery in the keyless
access remote is weak. 2 If the Keyless Access Remote Battery is
Weak P. 463
The engine may not start if the keyless access remote
is subjected to strong radio waves.
Do not hold the ENGINE START/STOP button to
start the engine.
If the engine does not start, wait at least 10 seconds
before trying again.

Shift Lever Operation
1Shift Lever OperationNOTICEWhen you change the shift lever from
(D to
(R and
vice versa, come to a complete stop and keep the
brake pedal depressed.
Operating the shift lever before the vehicle has come
to a complete standstill can damage the transmission.
Use the shift lever posit ion indicator to check the
lever position before pulling away.
Whichever position the shift lever is in when driving,
a blinking transmission indicator indicates a
transmission problem.
Avoid sudden acceleration and have the transmission
checked by a dealer as soon as possible.
The fuel supply may be cut off if you drive at engine
speeds in or over the tachometer’s red zone (engine
speed limit). If this happens, you may experience a
slight jolt.
It may not be possible to operate the shift lever if the
brake pedal is applied while the shift lever release
button is held down.
Depress the brake pedal first.

uuBraking uBrake System
372Driving
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.2 Brake Assist System P. 374
2 Anti-lock Brake System (ABS) P. 373■
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.
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.

uuBraking uAnti-lock Brake System (ABS)
Driving
Anti-lock Brake System (ABS)Helps prevent the wheels from locking up, and helps you retain steering control by
pumping the brakes rapidly, much faster than you.
The electronic brake distribution (EBD) system, which is part of the ABS, also
balances the front-to-rear braking distribution according to vehicle loading.
You should never pump the brake pedal. Let the ABS work for you by always
keeping firm, steady pressure on the brake pedal. This is sometimes referred to as
“stomp and steer.”■ABS operation
The brake pedal may pulsate slightly when the ABS is working. Keep holding the
pedal firmly down. On dry pavement, you will need to press on the brake pedal very
hard before the ABS activates. However, you may feel the ABS activate immediately
if you are trying to stop on snow or ice.
When the vehicle speed goes under 6 mph (10 km/h), the ABS stops.■
ABS
1 Anti-lock Brake System (ABS)NOTICEThe ABS may not function correctly if you use an
incorrect tire type and size.
When the ABS indicator comes on while driving,
there may be a problem with the system.
While normal braking is not affected, there is a
possibility of the ABS not operating. Have the vehicle
checked by a dealer immediately.
The ABS does not reduce the time or distance it takes
to stop the vehicle. It only helps with steering control
during hard braking.
In the following cases, your vehicle may need more
stopping distance than a vehicle without the ABS:•When driving on rough road surfaces, including
when driving on uneven surfaces, such as gravel or
snow.•When tire chains are installed.
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.
