uuBraking uBrake System
Driving
Your vehicle is equipped with disc brakes at all four wheels. The brake assist system
increases the stopping force when you depress the brake pedal hard in an
emergency situation. The an ti-lock brake system (ABS) helps you retain steering
control when brak ing very hard.

■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 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 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 can.
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. Depress the brake
pedal and keep holding the pedal firmly do wn. 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 yo u 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 correctly 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 wi ll not be 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 tire 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 the vehicle
accelerates.
•Brake pedal and/or the vehicle 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, gently lower the hood, then
remove your hand at a height of
approximately 12 inches (30 cm) and press
down firmly with both hands, making sure
both right and left latche s are firmly locked in
place.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.
NOTICE
Do not press the engine cover forcibly. This may
damage the engine cover and component parts.
When closing the hood, check that both right and
left latches are 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 cl eaned and lubricated.
Do not open the hood while the Auto Idle Stop
function is activated.

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.

Handling the Unexpected
If the Battery Is Dead
Turn off the power to electric devices, such as audio and lights. Turn off the engine,
then open the hood. 1.Open the cover on the positive + terminal.
2. Connect the first jump er 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 Procedure1If the Battery Is Dead
Securely attach the jumper cables clips so that they
do not come off when the e ngine vibrates. Also be
careful not to tangle the ju mper 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 engi ne from starting.
3WARNING
A battery can explode if you do not follow
the correct procedure, seriously injuring
anyone nearby.
Keep all sparks, open flames, and smoking
materials away from the battery.

5.Connect the other end of the second
jumper cable to the ground bolt as shown.
Do not connect this jumper cable to any
other part.
6. If your vehicle is connected to another
vehicle, start the assisting vehicle’s engine
and increase its rpm slightly.
7. Attempt to start your ve hicle’s engine. If it
turns over slowly, check that the jumper
cables have good metal-to-metal contact.
Once your vehicle’s engine has started, re move the jumper cables in the following
order.
1. Disconnect the jumper cable from your vehicle’s ground.
2. Disconnect the other end of the jump er cable from the booster battery -
terminal.
3. Disconnect the jumper cable from your vehicle’s battery + terminal.
4. Disconnect the other end of the jump er cable from the booster battery +
terminal.
Have your vehicle inspected by a n earby service station or a dealer.
■What to Do After the Engine Starts
1Jump Starting Procedure
The Vehicle Stability Assist
TM (VSA ®) system, Adaptive
Cruise Control (ACC) with Low Speed Follow, safety
support, and low tire pre ssure/TPMS indicators may
come on along with a message in the driver
information interface when you set the power mode
to ON after rec onnecting a battery.
Drive a short distance at mo re than 12mph (20 km/h).
Each indicator should go off. If any do not, have your
vehicle checked by a dealer.
