uuBrakinguBrake System
368Driving
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.2Brake Assist System P. 370
2Anti-lock Brake System (ABS) P. 369■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.

uuBrakinguAnti-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
1Anti-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 immediately after starting the engine or
while driving. This is normal.

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.
uIf it is stuck, you must detach it.
6.Wipe away dirt and dust adhering to the
contact surface of the oil filter base, and
install a new oil filter.
uApply 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.

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.
uIf 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.

Indicator, Coming On/BlinkingIf the Low Oil Pressure Indicator Comes On
■Reasons for the indicator to come on
Comes on when the engine oil pressure is low.■What to do as soon as the indicator comes on
1.Immediately park the vehicle on level ground in a safe place.
2.If necessary, turn the hazard warning lights on.■What to do after parking the vehicle
1.Stop the engine and let it sit for about three minutes.
2.Open the hood and check the oil level.2Oil Check P. 399
3.Start the engine and check the low oil pressure indicator.
uThe indicator goes off: Start driving again.
uThe indicator does not go off within 10 seconds: Stop the engine
and contact a dealer for repairs immediately.
If the Charging System Indicator Comes On
■Reasons for the indicator to come on
Comes on when the battery is not being charged.■What to do when the indicator comes on
Turn off the climate control system, rear defogger, and other electrical
systems, and immediately contact a dealer for repairs.
1If the Low Oil Pressure Indicator Comes OnNOTICERunning the engine with low oil pressure can cause
serious mechanical damage almost immediately.1If the Charging System Indicator Comes On
If you need to stop temporarily, do not turn off the
engine. Restarting the engine may rapidly discharge
the battery.

uuIndicator, Coming On/BlinkinguIf the Brake System Indicator (Red) Comes On
Handling the Unexpected
If the Brake System Indicator (Red) Comes On
■Reasons for the indicator to come on
•The brake fluid is low.
•There is a malfunction in the brake system.■What to do when the indicator comes on while driving
Press the brake pedal lightly to check pedal pressure.
•If normal, check the brake fluid level the next time you stop.
•If abnormal, take immediate action. If necessary, downshift the
transmission to slow the vehicle using engine braking.
If the Speed-Sensitive Electric Power Steering (EPS) System Indicator Comes On
■Reasons for the indicator to come on
•Comes on when there is a problem with the EPS system.
•If you depress the accelerator pedal repeatedly to increase the engine
speed while the engine is idling, the indicator comes on, and
sometimes the steering wheel becomes harder to operate.■What to do when the indicator comes on
Stop the vehicle in a safe place and restart the engine.
If the indicator comes on and stays on, immediately have your vehicle
inspected by a dealer.
1If the Brake System Indicator (Red) Comes On
Have your vehicle repaired immediately.
It is dangerous to drive with low brake fluid. If there
is no resistance from the brake pedal, stop
immediately in a safe place. If necessary downshift
the gears.
If the brake system indicator and ABS indicator come
on simultaneously, the electronic brake distribution
system is not working. This can result in vehicle
instability under sudden braking.
Have your vehicle inspected by a dealer immediately.
