When Driving
Starting the Engine
1.Make sure the parkin g brake is applied.
u The electric parking brake indicator
comes on for 15 seconds when you press
the electric parking brake switch.
2. Depress the brake pedal.
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 st art 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 and transmission clutch
actuator heater will impr ove starting and warming of
the engine. 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 batte ry in the keyless
access remote is weak.
2 If the Keyless Access Remote Battery is
Weak P. 647
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 30 seconds
before trying again.

NOTICE
When you change (D to (R and vice versa, come to
a complete stop and keep the brake pedal depressed.
Operating the shift button before the vehicle has
come to a complete standstill can damage the
transmission.
Use the gear position indicator and the shift button
indicator to check the gear position before selecting
a shift button.
If the indicator of the curren tly selected gear position,
or all the gear position indicators are blinking
simultaneously, there is a problem with the
transmission.
Avoid sudden acceleration and have the transmission
checked by a dealer as soon as possible.
The fuel supply may be cut of f if you drive at engine
speeds in or over the tachometer’s red zone (engine
speed limit). If this happe ns, you may experience a
slight jolt.

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.

2 Anti-lock Brake System (ABS) P. 534
■Foot Brake1Foot 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 me tallic friction sound when
applying the brakes, this is caused by the brake wear
indicator rubbing on the brake rotor and indicates
that the brake pads need to be replaced. Have the
vehicle checked by a deal er. If you hear only an
occasional squeak or squeal when you initially apply
the brake pedal, this may be normal and caused by
high frequency vibr ation of the brake pads against
the rotating brake disc.
Constantly using the brak e 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 pe dal 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 conf use drivers behind you.

uuBraking uAnti-lock Brake System (ABS)
Driving
Anti-lock Brake System (ABS)
Helps prevent the wheels from locking up, an d 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 distri bution 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 pe dal. 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.
ABS may activate when you depress the brake pedal when driving on:
• Wet or snow covered roads.
• Roads paved with stone.
• Roads with uneven surfaces, such as potholes, cracks, manholes, etc.
When the vehicle speed goes unde r 6 mph (10 km/h), the ABS stops.
■ABS1Anti-lock Brake System (ABS)
NOTICE
The ABS may not function correc tly if you use a tire of
the wrong size or type.
If the ABS indicator comes on while driving, there
may be a problem with the system.
While normal braking will not be affected, there is a
possibility that the ABS will not operating. Have your
vehicle checked by a dealer immediately.
The ABS is not designed for the purpose of reducing
the time or distance it takes for a vehicle to stop: It is
designed to limit brake lo ckup which can lead to
skidding and loss of steering control.
In the following cases, yo ur vehicle may need more
distance to stop than a vehicle without the ABS:
•You are driving on rough or uneven road surfaces,
such as gravel or snow.
•The tires are equipped with snow chains.
The following may be observed with the ABS system:
•Motor sounds coming from the engine
compartment when the brakes are applied, or
when system checks are being performed after the
engine has been started and while vehicle is
accelerates.
•Brake pedal and/or the ve hicle body vibration when
ABS activates.
These vibrations and sou nds are normal to ABS
systems and are no cause for concern.

Maintenance
Opening the Hood
1. Park the vehicle on a level surface, and set
the parking brake.
2. Pull the hood release handle under the
driver’s side lower co rner of the dashboard.
u The hood will pop up slightly.
3. Push the hood latch lever (located under
the front edge of the hood to the center) to
the side and raise the hood.
Once you have raised the hood slightly, you
can release the lever.
4. Lift the hood up most of the way.
u The hydraulic supports will lift it up the
rest of the way and hold it up.
When closing, lower it to approximately 12
inches (30 cm), then pr ess down firmly with
your hands.1 Opening the Hood
NOTICE
Do not open the hood when the wiper arms are
raised: The hood will strike the wipers, resulting in
possible damage to the hood and/or the wipers.
Do not press the engine cover forcibly. This may
damage the engine cover and component parts.
When closing the hood, check that the hood is
securely latched.
If the hood latch lever moves stiffly, or if you can
open the hood without lifti ng the lever, the latch
mechanism should be cleaned and lubricated.
Do not open the hood while the Auto Idle Stop
function is activated.

remaining oil.
5. Check that the filter ga sket is not stuck to
the engine contact surface.
u If it is stuck, you must detach it.
6. Wipe away dirt and dust adhering to the
contact surface of the engine block, and
install a new oil filter.
u Apply a light coat of new engine oil to
the filter gasket.
7. Put a new washer on the drain bolt, then
reinstall the drain bolt.

8. Pour the recommended engine oil into the
engine.
u Engine oil change capacity (including
filter):
5.7 US qt (5.4 L)
9. Reinstall the engine oil fill cap securely and
start the engine.
10. Run the engine for a few minutes, and
then check that there is no leak from the
drain bolt or oil filter.
11. Stop the engine, wait for three minutes,
and then check the oil level on the
dipstick.
u If necessary, add more engine oil.1Changing the Engine Oil and Oil Filter
You will need a special wrench to replace the oil
filter. You can buy this wrench from a dealer.
When installing the new oil filter, follow the
instructions supplied with the oil filter.
Reinstall the engine oil fill cap. Start the engine. The
low oil pressure indicator should go off within five
seconds. If it does not, turn off the engine, and check
your work.
