uuWhen Driving uLane Keeping Assist System (LKAS)*
302
Driving
Provides assistance to keep the vehicle in the center of the lane. When the vehicle
nears a white or yellow line, steering force of the electric power steering will become
stronger.
When the vehicle enters th e warning area, LKAS alerts you with beeps as well a
warning display.
■Lane Keep Support Function1 Lane Keeping Assist System (LKAS)*
The LKAS may not functi on as designed on while
driving in frequent stop and go traffic, or on roads
with sharp curves.
When it fails to detect lanes, the system will
temporarily be cancelled. When lane is detected,
system will recover automatically.
You can read about handling information for the
camera equipped with this system. 2 Front Sensor Camera
* P. 282
If the vehicle drifts toward ei ther left or right lane line
due to the system applying torque, turn off the LKAS
and have your vehicle checked by a dealer.

uuWhen Driving uAll-Wheel Drive (AWD) with Intelligent Control System*
Driving
All-Wheel Drive (AWD) with Intelligent Control System*
Your vehicle is equipped with the AWD wi th intelligent control system. When the
system senses a loss of front wheel tracti on, it automatically transfers some power
to the rear wheels. This allows you to ut ilize all available traction and may increase
mobility.
You still need to exercise the same care when accelerating, steering, and braking
that you would in a two wheel drive vehicle.
If you excessively spin all four wheels and overheat the AWD with intelligent control
system, only the front wheels receive power. Stop until the system cools down.
Tire Pressure Monitoring System (TPMS)
Monitors the tire pressure while you are
driving. If your vehicle’s tire pressure becomes
significantly low, the low tire pressure/TPMS
indicator comes on and a message appears on
the multi-information display.
1 All-Wheel Drive (AWD) with Intelligent Control 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 AWD with intelligent control system may not
function properly if tire ty pe 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. 380
1Tire Pressure Monitoring System (TPMS)
Conditions such as low ambient temperature and
altitude change directly affect tire pressure and can
trigger the low tire pressure/TPMS indicator to come
on.
2 If the Low Tire Pressure/TPMS Indicator
Comes On or Blinks P. 423
Tire pressure checked and inflated in:
•Warm weather can beco me under-inflated in
colder weather.
•Cold weather can become over-inflated in warmer
weather.
The low tire pressure/TPMS indicator will not come
on as a result of over inflation.
The TPMS audibly and visually informs you of
changes in tire pressure of the individual ti re that you
are adjusting using audibl e and visual indications.

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.
2 Brake Assist System P. 321
2 Anti-lock Brake System (ABS) P. 320
■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.
Your vehicle is equipped with a hydraulic brake
booster that, under certain conditions, such as
braking at high altitudes, supplements the vacuum
power assist. When the hydraulic brake booster
activates, you may hear a motor sound and a slight
vibration in the pedal. This is normal.

Handling the Unexpected
If a Tire Goes Flat
Changing a Flat Tire*
If a tire goes flat while driving, grasp the steering wheel firmly, and brake gradually
to reduce speed. Then, stop in a safe plac e. Replace the flat tire with a compact
spare tire. Go to a dealer as soon as possib le to have the full-size tire repaired or
replaced.
1. Park the vehicle on firm, level, non-slip pery surface and apply the parking brake.
2. Move the shift lever to
(P.
3. Turn on the hazard warning lights and set the power mode to VEHICLE OFF
(LOCK).
1Changing a Flat Tire*
Periodically check the tire pressure of the compact
spare. It should be set to the specified pressure.
Specified Pressure: 60 psi (420 kPa, 4.2 kgf/cm
2)
When driving with the compact spare tire, keep the
vehicle speed under 50 mph (80 km/h). Replace with
a full-size tire as soon as possible.
The compact spare tire and wheel in your vehicle are
specifically for this model. Do not use them with
another vehicle. Do not us e another type of compact
spare tire or wheel with your vehicle.
Do not mount tire chains on a compact spare tire.
If a chain-mounted front tire goes flat, remove one of
the full-size rear tires and replace it with the compact
spare tire. Remove the flat front tire and replace it
with the full-size tire that was removed from the rear.
Mount the tire chains on the front tire.
Do not use a puncture-repairi ng agent on a flat tire,
as it can damage the tire pressure sensor.

Handling the Unexpected
Temporarily Repairing a Flat Tire*
If the tire has a large cut or is otherwise severely damaged, you will need to have the
vehicle towed. If the tire only has a small puncture, from a nail for instance, you can
use the temporary tire repair kit so that you can drive to the nearest service station
for a more permanent repair.
If a tire goes flat while driving, grasp the steering wheel firmly, and brake gradually
to reduce speed. Then stop in a safe place.
1. Park the vehicle on a firm, level, and n on-slippery surface and apply the parking
brake.
2. Move the shift lever to
(P.
3. Turn on the hazard warning lights and set the power mode to VEHICLE OFF
(LOCK).
1Temporarily Repairing a Flat Tire*
The kit should not be used in the following situations.
Instead, contact a dealer or a roadside assistant to
have the vehicle towed.
•The tire sealant has expired.
•More than one tire is punctured.•The puncture or cut is larger than 3/16 inch (4mm).
•The tire side wall is da maged or the puncture is
outside the contact area.
•Damage has been caused by driving with the tire
extremely under inflated.
•The tire bead is no longer seated.
•The rim is damaged.
Do not remove a nail or screw that punctured the
tire. If you remove it from the tire, you may not be
able to repair the puncture using the kit.
NOTICE
Do not use a puncture-repairing agent other than the
one provided in the kit that came with your vehicle. If
a different agent is used, you may permanently
damage the tire pressure sensor.

uuEngine Does Not Start uEmergency Engine Stop
Handling the Unexpected
Emergency Engine Stop
The ENGINE START/STOP button may be used to stop the engine due to an
emergency situation even while driving. If you must stop the engine, do either of the
following operations:
• Press and hold the ENGINE START/STOP button for two seconds.
• Firmly press the ENGINE START/STOP button twice.
The steering wheel will not lock. However, because turning off the engine disables
the power assist the engine provides to the steering and braking systems, it will
require significantly more physical effort an d time to steer and slow the vehicle. Use
both feet on the brake pedal to slow down the vehicle and stop immediately in a
safe place.
The power mode is in ACCESSORY when the engine is stopped.
To change the mode to VEHICLE OF F, change the gear position to
(P after the
vehicle comes to a complete stop. Then press the ENGINE START/STOP button
twice without depressing the brake pedal.
1 Emergency Engine Stop
Do not press the button while driving unless it is
absolutely necessary for th e engine to be switched
off.
