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 your
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.

Continued
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 bolts on the undercarriage by
turning to the left and remove the under
cover.
5. Remove the oil filter and dispose of the
remaining oil.
6. Check that the filter gasket is not stuck to
the engine contact surface.
u If it is stuck, you must detach it.
7. 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.
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.

Inspecting and Changing Fuses
1. Set the power mode to VEHICLE OFF
(LOCK). Turn headlights and all accessories
off.
2. Remove the fuse box cover.
3. Check the large fuse in the engine
compartment.
u If the fuse is blown, use a Phillips-head
screwdriver to remove the screw and
replace it with a new one.
4. Inspect the small fuses in the engine
compartment and the vehicle interior.
u If there is a burned out fuse, remove it
with the fuse puller and replace it with a
new one.
1Inspecting and Changing FusesNOTICEReplacing a fuse with one that has a higher rating
greatly increases the chances of damaging the
electrical system.
Replace fuse with a spare fuse of the same specified
amperage.
Confirm the specified amperage using the charts on
P. 510 to 513.
There is a fuse puller in the engine compartment fuse
