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

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.

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 oil filter base, 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.

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.

Jump StartingTurn off the power to electric devices, such as audio and lights. Turn off the engine,
then open the hood. 1.Pull up on the engine cover, remove it from
the pins.
2. Connect the first jumper cable to your
vehicle’s battery + terminal.
3. Connect the other end of the first jumper
cable to the booster battery + terminal.
u Use a 12-volt booster battery only.
u When using an automotive battery
charger to boost your 12-volt battery,
select a lower charging voltage than 15-
volt. Check the charger manual for the
proper setting.
4. Connect the second jumper cable to the
booster battery - terminal.■
Jump Starting Procedure
1Jump Starting
Securely attach the jumper cables clips so that they
do not come off when the engine vibrates. Also be
careful not to tangle the jumper cables or allow the
cable ends to touch each other while attaching or
detaching the jumper cables.
Battery performance degrades in cold conditions and
may prevent the engine from starting.
