departure. It may further
provide an audible alert or the
driver seat may pulse
indicating that a lane marking
has been crossed. The system
does not provide a Lane
Departure Warning (LDW)
when intentionally steering
across a lane marker.
To turn LKA on and off, press
Aon the center stack.
If equipped, the indicator light
on the button comes on when
LKA is on and turns off when
LKA is disabled. In some
vehicles a long press of over
three seconds is required to
turn LKA off.
When on,
Ais white,
if equipped, indicating that the
system is not ready to assist.
Ais green if LKA is ready to
assist. LKA may assist by
gently turning the steering
wheel if the vehicle
approaches a detected lane
marking.
Ais amber when
assisting. It may also provide a
Lane Departure Warning (LDW) alert by flashing
A
amber if the vehicle crosses a
detected lane marking.
Additionally, there may be
three beeps, or the driver seat
may pulse three times, on the
right or left, depending on the
lane departure direction.
Take Steering
The LKA system does not
continuously steer the vehicle.
If LKA does not detect active
driver steering, an alert and
chime may be provided. Steer
the vehicle to dismiss. LKA
may become temporarily
unavailable after repeated
take steering alerts.
When the System Does
Not Seem to Work
Properly
The system performance may
be affected by:
.Close vehicles ahead.
.Sudden lighting changes,
such as when driving
through tunnels.
.Banked roads.
.Roads with poor lane
markings, such as two-lane
roads.
If the LKA system is not
functioning properly when lane
markings are clearly visible,
cleaning the windshield
may help.
A camera blocked message
may display if the camera is
blocked. Some driver
assistance systems may have
reduced performance or not
work at all. An LKA or LDW
unavailable message may
display if the systems are
temporarily unavailable. This
message could be due to a
blocked camera. The LKA
system does not need service.
Clean the outside of the
windshield behind the
rearview mirror.
LKA assistance and/or LDW
alerts may occur due to tar
marks, shadows, cracks in the
road, temporary or
construction lane markings,

When using a
weight-distributing hitch,
measure the front fender
height above the front axle
distance (2) before and after
connecting the trailer. Adjust
the spring bars until the front
fender height distance (2) is
approximately halfway
between the first and second
measurements.
Tires
.Do not tow a trailer while
using a compact spare tire
on the vehicle.
.Tires must be properly
inflated to support loads
while towing a trailer. See
Tires0400 for instructions
on proper tire inflation.
Safety Chains
Always attach chains between
the vehicle and the trailer, and
attach the chains to the holes
on the trailer hitch platform.
Instructions about safety chains may be provided by the
hitch manufacturer or by the
trailer manufacturer.
Cross the safety chains under
the tongue of the trailer to
help prevent the tongue from
contacting the road if it
becomes separated from the
hitch. Always leave just
enough slack so the
combination can turn. Never
allow safety chains to drag on
the ground.
Trailer Brakes
Loaded trailers over 450 kg
(1,000 lb) must be equipped
with brake systems and with
brakes for each axle. Trailer
braking equipment conforming
to Canadian Standards
Association (CSA) requirement
CAN3-D313, or its equivalent,
is recommended.
State or local regulations may
require trailers to have their
own braking system if the
loaded weight of the trailerexceeds certain minimums
that can vary from state to
state.
Read and follow the
instructions for the trailer
brakes so they are installed,
adjusted, and maintained
properly.
{Warning
Never attempt to tamper
with the hydraulic brake
system for your trailer
brakes. Do not connect a
trailer's hydraulic brake
system directly to your
vehicle's hydraulic brake
system. If you do, both the
vehicle antilock brakes and
the trailer brakes may not
function, which could result
in a crash.
Trailer Wiring Harness
lf equipped, the trailer wiring
harness, with a 7-pin
connector is mounted on the
trailer hitch.

the engine compartment fuse
block. The electric trailer brake
controller should be installed
by your dealer or a qualified
service center.
Trailer Lamps
Always check that all trailer
lamps are working at the
beginning of each trip, and
periodically on longer trips.
Turn Signals When
Towing a Trailer
When properly connected, the
trailer turn signals will
illuminate to indicate the
vehicle is turning, changing
lanes, or stopping. When
towing a trailer, the arrows on
the instrument cluster will
illuminate even if the trailer is
not properly connected or the
bulbs are burned out.
Trailer Sway
Control (TSC)
Vehicles with StabiliTrak/
Electronic Stability Control
(ESC) have a Trailer Sway
Control (TSC) feature. Trailer
sway is unintended
side-to-side motion of a trailer
while towing. If the vehicle is
towing a trailer and the TSC
detects that sway is
increasing, the vehicle brakes
are selectively applied to help
reduce excessive trailer sway.
If equipped with the
Integrated Trailer Brake
Control (ITBC) system, and the
trailer has an electric brake
system, StabiliTrak/ESC may
also apply the trailer brakes.
If TSC is enabled, the Traction
Control System (TCS)/
StabiliTrak/ESC warning light
will flash on the instrument
cluster. Reduce vehicle speed
by gradually removing your
foot from the accelerator
pedal. If trailer sway continues,
StabiliTrak/ESC can reduce
engine torque to help slow the
vehicle. TSC will not function if
StabiliTrak/ESC is turned off.
See Traction Control/
Electronic Stability Control
0276.
{Warning
Trailer sway can result in a
crash and in serious injury or
death, even if the vehicle is
equipped with TSC.
If the trailer begins to sway,
reduce vehicle speed by
gradually removing your foot
from the accelerator. Then
pull over to check the trailer
and vehicle to help correct
possible causes, including an

Engine Oil
To ensure proper engine
performance and long life,
careful attention must be paid
to engine oil. Following these
simple, but important steps
will help protect your
investment:
.Use engine oil approved to
the proper specification and
of the proper viscosity
grade. See “Selecting the
Right Engine Oil” in this
section.
.Check the engine oil level
regularly and maintain the
proper oil level. See
“Checking Engine Oil” and
“When to Add Engine Oil” in
this section.
.Change the engine oil at the
appropriate time. See Engine
Oil Life System 0373.
.Always dispose of engine oil
properly. See “What to Do
with Used Oil” in this section.
Checking Engine Oil
Check the engine oil level
regularly, every 650 km
(400 mi), especially prior to a
long trip. The engine oil
dipstick handle is a loop. See
Engine Compartment
Overview0367 for the
location.
{Warning
The engine oil dipstick
handle may be hot; it could
burn you. Use a towel or
glove to touch the dipstick
handle.
If a low oil Driver Information
Center (DIC) message displays,
check the oil level.
Follow these guidelines:
.To get an accurate reading,
park the vehicle on level
ground. Check the engine oil
level after the engine has
been off for at least two
hours. Checking the engine
oil level on steep grades or
too soon after engine
shutoff can result in
incorrect readings. Accuracy
improves when checking a
cold engine prior to starting.
Remove the dipstick and
check the level.
.If unable to wait two hours,
the engine must be off for at
least 15 minutes if the

you could be burned. Never
turn the cap when the
cooling system, including the
pressure cap, is hot. Wait for
the cooling system and
pressure cap to cool.
Caution
Failure to follow the specific
coolant fill procedure could
cause the engine to
overheat and could cause
system damage. If coolant is
not visible in the surge tank,
contact your dealer.
The coolant surge tank
pressure cap can be removed
when the cooling system,
including the surge tank
pressure cap and upper
radiator hose, is no longer hot.
Coolant Fill Instructions
(3.6L Engine Only)
1. Turn the pressure cap slowly counterclockwise.
If a hiss is heard, wait for
that to stop. A hiss means
there is still some
pressure left.
2. Keep turning the pressure cap slowly and remove it.
3. Fill the coolant surge tankwith the proper mixture to
the mark pointed to on the
front of the coolant
surge tank.
4. With the coolant surge tank pressure cap off,
start the engine and let it
run until you can feel the
upper radiator hose
getting hot. Watch out for
the engine cooling fans. By
this time, the coolant level
inside the coolant surge
tank may be lower. If the
level is lower, add more of
the proper mixture to the

LED Lighting
This vehicle has all LED lamps.
For replacement of any LED
lighting assembly, contact
your dealer.
Electrical System
Electrical System
Overload
The vehicle has fuses and
circuit breakers to protect
against an electrical system
overload.
When the current electrical
load is too heavy, the circuit
breaker opens and closes,
protecting the circuit until the
current load returns to normal
or the problem is fixed. This
greatly reduces the chance of
circuit overload and fire
caused by electrical problems.Fuses and circuit breakers
protect power devices in the
vehicle.
If there is a problem on the
road and a fuse needs to be
replaced, the same amperage
fuse can be borrowed. Choose
some feature of the vehicle
that is not needed to use and
replace it as soon as possible.
To check a fuse, look at the
band inside the fuse. If the
band is broken or melted,
replace the fuse. Be sure to
replace a bad fuse with a fuse
of the identical size and rating.
Replacing a Blown Fuse
1. Turn off the vehicle.
2. Locate the fuse puller in
the engine compartment
fuse block.
