uuWhen Driving uLane Keeping Assist System (LKAS)
Continued
Driving
The system may not detect lane markings and therefore may not keep the vehicle in
the middle of a lane under certain conditions, including the following:
■Environmental conditions
• Driving in bad weather (rain, fog, snow, etc.).
• Sudden changes between light and dark, such as an entrance or exit of a tunnel.
• There is little contrast between lane lines and the roadway surface.
• Driving into low sunlight (e.g., at dawn or dusk).
• Strong light is reflec ted onto the roadway.
• Driving in the shadows of trees, buildings, etc.
• Shadows of adjacent objects are parallel to lane markings.
• Roadway objects or structures are misinterpreted as lane markers.
• Reflections on the interi or of the windshield.
• Driving at night or in a dark condition such as a tunnel.

Driving
■Roadway conditions
• Driving on a snowy or wet roadway (obs cured lane marking, vehicle tracks,
reflected lights, road spray, high contrast).
• Driving on a road with temporary lane markings.
• Faint, multiple, or varied lane markings are visible on the roadway due to road

• The roadway has merging, split, or crossing lines (e.g., such as at an intersection
or crosswalk).
• The lane markings are extremely narrow, wide, or changing.
• The vehicle in front of you is driving near the lane lines.
• The road is hilly or the vehicle is approaching the crest of a hill.
• Driving on rough or unpaved roads, or over bumpy surfaces.
• When objects on the road (curb, guard rail, pylons, etc.) are recognized as white
lines (or yellow lines).
• Driving on roads with double lines.
■Vehicle conditions
• Headlight lenses are dirty or the headlights are not properly adjusted.
• The outside of the windshield is streake d or blocked by dirt, mud, leaves, wet
snow, etc.
• The inside of the windshield is fogged.
• The camera temperature gets too high.

uuWhen Driving uAgile Handling Assist
Driving
Agile Handling Assist
Lightly brakes each of the front and rear wheels, as needed, when you turn the
steering wheel, and helps support the vehicle’s stability and performance during
cornering.1 Agile Handling Assist
The agile handling assist ca nnot enhance stability in
all driving situations. You still need to drive and
corner at speeds appropriate for the conditions and
always leave a sufficient margin of safety.
When the VSA ® system indicator comes on and stays
on while driving, the agil e handling assist does not
activate.
You may hear a sound coming from the engine
compartment while the agile handling assist is
activated. This is normal.

uuWhen Driving uTire Pressure Monitoring System (TPMS) with Tire Fill Assist
Driving
Tire Pressure Monitoring System (TPMS) with Tire
Fill Assist
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 MID.
1 Tire Pressure Monitoring System (TPMS) with Tire Fill Assist
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. 645
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.
If a change in tire pressure has been significant, the
system beeps and the hazard lights flash continuously
for five seconds when the specified tire pressure is
reached. Stop filling the tire.

uuWhen Driving uTire Pressure Monitoring System (TPMS) with Tire Fill Assist
Driving
To select the tire pressure monitor, set the power
mode to ON, and roll the multi-function
steering-wheel controls until you see the tire
pressure screen.
The pressure for each tire is displayed in psi
(U.S.) or kPa (Canada).
Tire Pressures Low is displayed when a tire
has significantly low pressure. The specific tire
is displayed on the screen.
■Tire Pressure Monitor1 Tire Pressure Monitor
The pressure displayed on the MID can be slightly
different from the actual pr essure as measured by a
gauge. If there is a signifi cant difference between the
two values, or if the low tire pressure/TPMS indicator
and the message on the MID do not go off after you
have inflated the tire to the specified pressure, have
the system checked by a dealer.
Tire Pressure Monitor Problem may appear if you
drive with the compact spare tire
*, or there is a
problem with the TPMS.

uuWhen Driving uHigh Voltage Battery
Driving
High Voltage Battery
The High Voltage battery gradually discharges when the vehicle is not in use. As a
result, if your vehicle is parked for an ex tended period of time, the battery level may
get low. Keeping your vehicle’s battery le vel low can shorten the battery life. To
maintain the battery, drive your vehicle fo r more than 30 minutes to recharge the
battery at least once every three months.
To help maintain the battery life, when parking under the direct sunlight during
summer, try find a shaded area.

Braking
Brake System
Use the parking brake to keep the vehicle stationary when parked. When the
parking brake is applied, you can manu ally or automatically release it.
■To apply
The electric parking brake can be applied any
time the vehicle has battery, no matter which
position the power mode is in.
Press the electric parking brake switch gently
and securely. u The electric parking brake indicator
comes on.
■Parking Brake1Brake System
When you depress the brak e pedal, you may hear a
whirring sound from the engine compartment. This is
because the brake system is in operation, and it is
normal.
1 Parking Brake
You may hear the electric parking brake system
motor operating from the re ar wheel area when you
apply or release the parking brake. This is normal.
The brake pedal may slightly move due to the electric
parking brake system opera tion when you apply or
release the parking br ake. This is normal.
You cannot apply or release the parking brake if the
12-volt battery goes dead. 2 Jump Starting P. 637
If you press and hold the electric parking brake
switch while driving, the brakes on all four
wheels are applied by the VSA ® system until the
vehicle comes to a stop. The electric parking
brake then applies, and the switch should be
released.Electric Parking

Driving
Your vehicle is equipped with disc brakes at all four wh eels. 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 regene rative braking by taking
your foot off the accelera tor 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 conf use drivers behind you.
