uuWhen Driving uLane Departure Warning (LDW)
Driving
LDW may not activate or may not recognize lanes, and may activate even when
keeping in the middle of a lane, under the following conditions.■
LDW Limitations
Condition
●When you drive in bad weather (rain, fog, etc.).●A heavy load in the rear or modifications to the suspension tilts your vehicle.●An abnormal tire condition is detected (wrong tire size, flat tire, etc.).●When the windshield is blocked by dirt, mud, leaves, wet snow, etc.●When the temperature inside the system is high.●A sudden change between light and dark such as an entrance or exit of a tunnel.●You drive into the sunlight (e.g. at dawn or dusk).●When the windshield is dirty or cloudy.●When you drive in the shadows of trees, buildings, etc.●When you drive on a wet road surface following another vehicle.u
The camera may perceive the tire tracks in the water as lane lines.
●When there is snow or wheel tracks on the side of the road.●When the road has many repaired area or an erased lane line.●When the vehicle is running over painted signs or crosswalk markings.●When you drive in a lane with worn-out lane markings.

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 Brake Assist System P. 391
2 Anti-lock Brake System (ABS) P. 390■
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.
Your vehicle is equipped with a hydraulic brake
booster that, under certain conditions, such as
braking at high altitudes, supplements the vacuum
power assist. When the hydraulic brake booster
activates, you may hear a motor sound and a slight
vibration in the pedal. This is normal.

uuBraking uAnti-lock Brake System (ABS)
Driving
Anti-lock Brake System (ABS)Helps prevent the wheels from locking up, and help s 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.

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
lower left corner of the dashboard.
u The hood will pop up slightly.
3. Push up the hood latch lever in the center
of the hood to release the lock mechanism,
and open the hood.
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 press down firmly with
your hands.
1 Opening the HoodNOTICEDo not open the hood when the wiper arms are
raised.
The hood will strike the wipers, and may damage
either the hood or the wipers.
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 lifting the lever, the latch
mechanism should be cleaned and lubricated.

uuMaintenance Under the Hood uChanging the Engine Oil and Oil Filter
Maintenance
Changing the Engine Oil and Oil FilterYou must change the engine oil and oil filter regularly in order to maintain the
engine’s lubrication. The engine may be damaged if they are not changed regularly.
Change the oil and filter in accordance with the maintenance message on the multi-
information display.
1.Run the engine until it reaches normal
operating temperature, and then turn the
engine off.
2. Open the hood and remove the engine oil
fill cap.
3. Remove the drain bolt and washer from
the bottom of the engine, and drain the
oil into a suitable container.
4. Remove the oil filter and dispose of the
remaining oil.
5. Check that the filter gasket 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 oil filter rubber seal.
7. Put a new washer on the drain bolt, then
reinstall the drain bolt.

1Changing the Engine Oil and Oil FilterNOTICEYou may damage the environment if you do not
dispose of the oil in a suitable way. If you are
changing the oil by yourself, appropriately dispose of
the used oil. Put the oil in a sealed container and take
it to a recycling center. Do not throw the oil away
into a garbage can or onto the ground.
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.
