Brake System
It illuminates when you apply the
parking brake and the ignition is
on. If it illuminates when your
vehicle is moving, make sure the
parking brake is released. If the
parking brake is released, this
indicates low brake fluid level or the brake
system requires service. Have your vehicle
checked as soon as possible.
Note: Indicators may vary depending on
region.
Door Ajar It illuminates when you switch the
ignition on and remains on if any
door is open.
Electric Parking Brake It illuminates or flashes when the
electric parking brake requires
service. Engine Coolant Temperature If it illuminates, safely stop your
vehicle and switch your vehicle off.
Fasten Seatbelt It illuminates and a tone sounds
until you fasten the seatbelts.
Hood Ajar It illuminates when the ignition is
on and the hood is not completely
closed.
Liftgate Ajar It illuminates when the ignition is
on and the liftgate is not
completely closed.
Low Beam Warning It illuminates when the low beam
headlamp requires service. Have
the system checked as soon as
possible. Low Fuel Level It illuminates when the fuel level is
low.
Low Tire Pressure It illuminates when your tire
pressure is low. If illuminated,
check your tire pressure as soon
as possible. If it begins to flash at anytime,
have the system checked as soon as
possible.
Low Washer Fluid Level It illuminates when the washer fluid
is low.

HOW DOES ALL-WHEEL DRIVE
WORK
All-wheel drive uses all four wheels to power
the vehicle. This increases traction, enabling
you to drive over terrain and road conditions
that a conventional two-wheel drive vehicle
cannot. The AWD system turns on when
needed and does not require input from you.
Note:
The AWD feature gives your vehicle
some limited off-road capabilities in which
driving surfaces are relatively level,
obstruction-free and otherwise similar to
normal on-road driving conditions. Operating
your vehicle in conditions other than those,
could subject the vehicle to excess stress
which might result in damage which is not
covered under your warranty. ALL-WHEEL DRIVE PRECAUTIONS WARNING: If you are driving in
slippery conditions that require tire chains
or cables, then it is critical that you drive
cautiously. Keep speeds down, allow for
longer stopping distances and avoid
aggressive steering to reduce the chances
of a loss of vehicle control which can lead
to serious injury or death. If the rear end
of your vehicle slides while cornering, steer
in the direction of the slide until you regain
control of your vehicle. WARNING:
Do not become
overconfident in the ability of all-wheel
drive vehicles. Although an all-wheel drive
vehicle may accelerate better than a
two-wheel drive vehicle in low traction
situations, it won't stop any faster than
two-wheel drive vehicles. Always drive at
a safe speed. ALL-WHEEL DRIVE LIMITATIONS
When using a mismatch spare tire on your
vehicle the all-wheel drive system can
become limited in function. To regain full
all-wheel drive capabilities have the standard
wheel replaced.
Different tire sizes between the front and
rear axles can cause system damage, or
disable the all-wheel drive system.
ALL-WHEEL DRIVE DRIVING HINTS
Emergency Maneuvers
In an unavoidable emergency where a
sudden sharp turn will be made, remember
to avoid over-driving your vehicle, for
example, turn the steering wheel only as
rapidly and as far as required to avoid the
emergency. Apply smooth pressure to the
accelerator pedal or brake pedal as needed.

(If Equipped)

Once through water, always try the brakes.
Wet brakes will not stop your vehicle as
quickly as dry brakes. Apply light pressure
to the brake pedal while slowly moving the
vehicle to dry the brakes.
Note:
Driving through deep water could
cause damage to the transmission. If the
front or rear axle is submerged in water, the
axle lubricant and power transfer unit
lubricant should be checked and changed
if necessary.
Driving on Hilly or Sloping Terrain
Although natural obstacles could make it
necessary to travel diagonally up or down a
hill or steep incline, you should try to drive
straight up or straight down.
Note: Avoid turning on steep slopes or hills.
A danger lies in losing traction, slipping
sideways and possible vehicle roll over.
Whenever driving on a hill, determine
beforehand the route you can use. Do not
drive over the crest of a hill without seeing
what conditions are on the other side. Do
not drive in reverse over a hill without the
aid of an observer. Apply just enough power to the wheels to
climb the hill. Too much power will cause the
tires to slip, spin or lose traction, and you
could lose control of your vehicle.
When descending a steep hill, do not
descend the hill in neutral. Avoid sudden
hard braking to keep the front wheels rolling
and to maintain your vehicle's steering.
Note:
If your vehicle has anti-lock brakes,
apply the brakes steadily. Do not pump the
brakes.
Note: If your vehicle gets stuck driving on
hilly or sloping terrain, it may be rocked out
by shifting between forward and reverse
gears, stopping between shifts in a steady
pattern. Press lightly on the accelerator in
each gear.
Note: Do not rock your vehicle if the engine
is not at normal operating temperature, as
damage to the transmission may occur.
Note: Do not rock your vehicle for more than
a minute, as damage to the transmission
and tires may occur or the engine may
overheat. Driving on Snow and Ice WARNING: If you are driving in
slippery conditions that require tire chains
or cables, then it is critical that you drive
cautiously. Keep speeds down, allow for
longer stopping distances and avoid
aggressive steering to reduce the chances
of a loss of vehicle control which can lead
to serious injury or death. If the rear end
of your vehicle slides while cornering, steer
in the direction of the slide until you regain
control of your vehicle.
Avoid sudden applications of power and
quick changes of direction on snow and ice.
Apply the accelerator slowly and steadily
when starting from a full stop.
Avoid sudden braking. Although an all-wheel
drive vehicle accelerates better than a
two-wheel drive vehicle in snow and ice, it
cannot stop any faster as braking occurs at
all four wheels. Do not become
overconfident of the road conditions.

LANE KEEPING SYSTEM
LIMITATIONS
The lane keeping system only operates when
the vehicle speed is greater than 40 mph
(64 km/h).
The system works when the camera can
detect at least one lane marking.
The lane keeping system may not correctly
operate in any of the following conditions:
• The lane keeping system does not detect
at least one lane marking.
• You switch the turn signal on.
• You apply direct steering, accelerate fast
or brake hard.
• The vehicle speed is less than
40 mph
(64 km/h).
• The anti-lock brake, stability control or
traction control system activates.
• The lane is too narrow.
• Something is obscuring the camera or it
is unable to detect the lane markings due
to environment, traffic or vehicle
conditions. The lane keeping system may not correct
lane positioning in any of the following
conditions:
•
High winds.
• Uneven road surfaces.
• Heavy or uneven loads.
• Incorrect tire pressure.
SWITCHING THE LANE KEEPING
SYSTEM ON AND OFF To activate the lane keeping
system, press the button on the
turn signal lever.
Note: The system stores the on or off setting
until manually changed, unless it detects a
MyKey™. If the system detects a MyKey™, it
defaults to on and the mode is set to alert.
Note: If the system detects a MyKey™,
pressing the button does not affect the on
or off status of the system. You can only
change the mode and intensity settings. SWITCHING THE LANE KEEPING
SYSTEM MODE
The lane keeping system has different
settings that you can view or adjust using
the information display.
The system stores the last known selection
for each of these settings. You do not need
to readjust your settings each time you
switch on the system.
To change the lane keeping system mode,
use the instrument cluster display:
1. Using the instrument cluster display
controls on the steering wheel, select
SETTINGS
.
2. Select
Driver assistance.
3. Select
Lane keeping system.
4. Select
Mode.
5. Select a mode.
Note: The system remembers the last setting
when you start your vehicle. If the system
detects a MyKey™, it defaults to the last
setting for that MyKey™.

Why is the feature not available (lane markings are gray) when I can s\
ee the lane markings on the road?
Lane width is too narrow or too wide.
You have not calibrated the camera after a windshield replacement. Driving on tight or on uneven roads. Why does the vehicle not come back toward the middle of the lane, as expected, in the Aid, or Aid + Alert mode?
High cross winds are present.There is a large road crown.
Rough roads, grooves or shoulder drop-offs.
Heavy, uneven loading of the vehicle or improper tire inflation pressure. You changed the tires or modified the suspension.
