Driving
Intelligent Variable Torque ManagementTM (i-VTM4TM)
AWD System*
The Intelligent Variable Torque Management System (i-VTM4) is a full time all wheel
drive system that automatically controls and transfers varying amount of engine
torque to all wheels independently according to the driving conditions.
You still need to exercise the same care when accelerating, steering, and braking
that you would in a two wheel drive vehicle.
If the AWD light blinks while driving, it i ndicates the differential temperature is too
high. If this happens, pull to the side of the ro ad when it is safe, shift to park, an idle
the engine idle until the indicator goes ou t. If the indicator does not go out, take
your vehicle to a dealer to have it checked.1 Intelligent Variable Torque ManagementTM (i-VTM4TM) AWD
System*
NOTICE
Do not continuously spin the front tires of your
vehicle. Continuously spinning the front tires can
cause transmission or re ar differential damage.
The i-VTM4 system may not function properly if tire
type and size are mixed. Make sure to use the same
size and type of tire, and the air pressures as
specified. 2 Tire and Wheel Replacement P. 553

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.

■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 brak e 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.
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. 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.
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 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 ti me or distance it takes
to stop the vehicle. It only helps with steering control
during hard braking.
In the following cases, yo ur vehicle may need more
stopping distance than a vehicle without the ABS:
•When driving on rough road surfaces, including
when driving on uneven surf aces, such as gravel or
snow.
•When tire chains are installed.
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 vehicle is
accelerates.
•Brake pedal and/or the ve hicle body vibration when
ABS activates.
These vibrations and sounds are normal to ABS
systems and are no cause for concern.

4. Remove the oil filter and dispose of the
remaining oil.
5. Check that the filter ga sket 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.
u Tightening torque:
29 lbf∙ft (39 N∙m, 4.0 kgf∙m)
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.

Handling the Unexpected
Jump Starting
Turn 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.
u Start on the passenger side and lift the
outermost edge of the cover.
u Move towards the driver side while
applying uniform upward pressure.
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
volts. Check the ch arger manual for the
proper setting.
4. Connect the second jumper cable to the
booster battery - terminal.
■Jump Starting Procedure1Jump Starting
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 engine hanger as
shown. Do not connect this jumper cable to
any other part.
6. If your vehicle is connected to another
vehicle, start the assi sting vehicle’s engine
and increase its rpm slightly.
7. Attempt to start your vehicle’s engine. If it
turns over slowly, check that the jumper
cables have good metal-to-metal contact.
