Driving and Operating 213If the LCA displays do not light up
when moving vehicles are in the
side blind zone or rapidly
approaching this zone and the
system is clean, the system may
need service. Take the vehicle to
your dealer.
Radio Frequency Information See Radio Frequency Statement
0 335 .
Lane Keep Assist (LKA) If equipped, LKA may help avoid
crashes due to unintentional lane
departures. This system uses a
camera to detect lane markings
between 60 km/h (37 mph) and
180 km/h (112 mph). It may assist by
gently turning the steering wheel if
the vehicle approaches a detected
lane marking. It may also provide a
Lane Departure Warning (LDW)
alert if the vehicle crosses a
detected lane marking. LKA can be
overridden by turning the steering
wheel. This system is not intended
to keep the vehicle centered in the
lane. LKA will not assist and alert if the turn signal is active in the
direction of lane departure, or if it
detects that you are accelerating,
braking, or actively steering.
{ WarningThe LKA system does not
continuously steer the vehicle.
It may not keep the vehicle in the
lane or give a Lane Departure
Warning (LDW) alert, even if a
lane marking is detected.
The LKA and LDW systems
may not:
.
Provide an alert or enough
steering assist to avoid a
lane departure or crash.
.
Detect lane markings under
poor weather or visibility
conditions. This can occur if
the windshield or
headlamps are blocked by
dirt, snow, or ice; if they are
not in proper condition; or if
the sun shines directly into
the camera.
(Continued) Warning (Continued) .
Detect road edges.
.
Detect lanes on winding or
hilly roads.
If LKA only detects lane markings
on one side of the road, it will
only assist or provide an LDW
alert when approaching the lane
on the side where it has detected
a lane marking. Even with LKA
and LDW, you must steer the
vehicle. Always keep your
attention on the road and
maintain proper vehicle position
within the lane, or vehicle
damage, injury, or death could
occur. Always keep the
windshield, headlamps, and
camera sensors clean and in
good repair. Do not use LKA in
bad weather conditions or on
roads with unclear lane markings,
such as construction zones.

214 Driving and Operating
{ WarningUsing LKA while towing a trailer
or on slippery roads could cause
loss of control of the vehicle and
a crash. Turn the system off.
How the System Works LKA uses a camera sensor installed
on the windshield ahead of the
rearview mirror to detect lane
markings. It may provide brief
steering assist if it detects an
unintended lane departure. It may
further provide an audible alert or
the driver seat may pulse indicating
that a lane marking has been
crossed.
To turn LKA on and off, press
Aon the steering wheel. If equipped,
the indicator light on the button
comes on when LKA is on and turns
off when LKA is disabled.
When on,
A is white, if equipped,
indicating that the system is not
ready to assist.
A is green if LKA is ready to assist and alert if the
vehicle crosses detected markings
on one or both sides of the lane.
LKA may assist by gently turning
the steering wheel if the vehicle
approaches a detected lane
marking.
A is 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, chime, or DIC
message 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 or in
construction zones.
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. Cleaning the outside
of the windshield behind the
rearview mirror may correct the
issue. The LKA system does not
need service.

Driving and Operating 221Warning (Continued).
Adjust the climate control
system to a setting that
brings in only outside air.
See “ Climate Control
Systems ” in the Index.
For more information about
carbon monoxide, see Engine
Exhaust 0 181 .
Towing a trailer requires experience.
The combination of the vehicle and
trailer is longer and not as
responsive as the vehicle itself. Get
used to the handling and braking of
the combination by driving on a
level road surface before driving on
public roads.
The trailer structure, the tires, and
the brakes must be all be rated to
carry the intended cargo.
Inadequate trailer equipment can
cause the combination to operate in
an unexpected or unsafe manner.
Before driving, inspect all trailer
hitch parts and attachments, safety
chains, electrical connectors, lamps, tires, and mirrors. See Towing
Equipment 0 226 . If the trailer has
electric brakes, start the
combination moving and then
manually apply the trailer brake
controller to check the trailer brakes
work. During the trip, occasionally
check that the cargo and trailer are
secure and that the lamps and any
trailer brakes are working.
Towing with a Stability Control
System When towing, the stability control
system might be heard. The system
reacts to vehicle movement caused
by the trailer, which mainly occurs
during cornering. This is normal
when towing heavier trailers.
Following Distance Stay at least twice as far behind the
vehicle ahead as you would when
driving without a trailer. This can
help to avoid heavy braking and
sudden turns. Passing More passing distance is needed
when towing a trailer. The
combination of the vehicle and
trailer will not accelerate as quickly
and is much longer than the vehicle
alone. It is necessary to go much
farther beyond the passed vehicle
before returning to the lane. Pass
on level roadways. Avoid passing
on hills if possible.
Backing Up Hold the bottom of the steering
wheel with one hand. To move the
trailer to the left, move that hand to
the left. To move the trailer to the
right, move that hand to the right.
Always back up slowly and,
if possible, have someone
guide you.

240 Vehicle Care the best conditions, the oil life
system may indicate that an oil
change is not necessary for up to a
year. The engine oil and filter must
be changed at least once a year
and at this time the system must be
reset. Your dealer has trained
service people who will perform this
work and reset the system. It is also
important to check the oil regularly
over the course of an oil drain
interval and keep it at the proper
level.
If the system is ever reset
accidentally, the oil must be
changed at 5 000 km (3,000 mi)
since the last oil change.
Remember to reset the oil life
system whenever the oil is changed.
How to Reset the Engine Oil
Life System
Reset the system whenever the
engine oil is changed so that the
system can calculate the next
engine oil change. To reset the
system: 1. Using the DIC controls on the
right side of the steering wheel,
display REMAINING OIL LIFE
on the DIC. See Driver
Information Center (DIC) (Base
Level) 0 123 or
Driver Information Center (DIC)
(Uplevel) 0 126 . When
remaining oil life is low, the
CHANGE ENGINE OIL SOON
message will appear on the
display.
2. Press
V on the DIC controls
and hold down for a few
seconds to clear the CHANGE
ENGINE OIL SOON message
and reset the oil life at 100%.
Be careful not to reset the oil
life display accidentally at any
time other than after the oil is
changed. It cannot be reset
accurately until the next oil
change.
The system is reset when the
CHANGE ENGINE OIL SOON
message is off. If the CHANGE ENGINE OIL SOON
message comes back on when the
vehicle is started, the engine oil life
system has not been reset. Repeat
the procedure.
Automatic Transmission
Fluid It is not necessary to check the
transmission fluid level.
A transmission fluid leak is the only
reason for fluid loss. If a leak
occurs, take the vehicle to your
dealer and have it repaired as soon
as possible.
Change the fluid at the intervals
listed in Maintenance Schedule
0 311 , and be sure to use the
transmission fluid listed in
Recommended Fluids and
Lubricants 0 320 .
Caution
Use of the incorrect automatic
transmission fluid may damage
the vehicle, and the damage may
