8-10 Climate Controls
For vehicles with heated outside
rearview mirrors, they turn on when
the rear window defogger button is
on and help to clear fog or frost from
the surface of the mirror. See
Heated Mirrors on page 2‑18.
Notice:Do not try to clear frost
or other material from the inside
of the front windshield and rear
window with a razor blade or
anything else that is sharp. This
may damage the rear window
defogger grid and affect your
radio's ability to pick up stations
clearly. The repairs would not be
covered by your warranty.
((Heated Steering Wheel): For
vehicles with this feature, press to
turn on or off. See Heated Steering
Wheel on page 5‑3.
Remote Start Climate Control
Operation (If Equipped): When
the vehicle is started remotely, the
climate control system will use the
last setting before the vehicle shut
off. If automatic operation was set,
the fan speed will adjust to maximize heating or cooling.
If manual operation was set, the fan
speed will be limited to the last
setting. In extreme temperatures,
the system may not be able to heat
or cool the vehicle to the preset
temperature during the remote start
run time.
The rear window defogger turns on
if it is cold outside.
Sensor
The solar sensor, located on top of
the instrument panel near the
windshield, monitors the solar heat.
The climate control system uses the
sensor information to adjust the
temperature, fan speed,
recirculation, and air delivery mode
for best comfort.
Do not cover the sensor; otherwise
the automatic climate control system
may not work properly.
Air Vents
Use the louvers located on the air
vents to change the direction of the
airflow.
To open the vent, move the
thumbwheel to
t. To close the vent,
move the thumbwheel to
l.
For vehicles with eAssist, there is a
battery cooling air vent located on

Brakes
Antilock Brake
System (ABS)
This vehicle has the Antilock Brake
System (ABS), an advanced
electronic braking system that helps
prevent a braking skid.
When the engine is started and the
vehicle begins to drive away, ABS
checks itself. A momentary motor or
clicking noise might be heard while
this test is going on, and it might
even be noticed that the brake
pedal moves a little. This is normal.
If there is a problem with ABS, this
warning light stays on. SeeAntilock
Brake System (ABS) Warning Light
on page 5‑21. If driving safely on a wet road and it
becomes necessary to slam on the
brakes and continue braking to
avoid a sudden obstacle, a
computer senses that the wheels
are slowing down. If one of the
wheels is about to stop rolling, the
computer will separately work the
brakes at each wheel.
ABS can change the brake pressure
to each wheel, as required, faster
than any driver could. This can help
the driver steer around the obstacle
while braking hard.
As the brakes are applied, the
computer keeps receiving updates
on wheel speed and controls
braking pressure accordingly.
Remember: ABS does not change
the time needed to get a foot up to
the brake pedal or always decrease
stopping distance. If you get too
close to the vehicle in front of you,
there will not be enough time to
apply the brakes if that vehicle
suddenly slows or stops. Always
leave enough room up ahead to
stop, even with ABS.
Using ABS
Do not pump the brakes. Just hold
the brake pedal down firmly and let
ABS work. You might hear the ABS
pump or motor operating and feel
the brake pedal pulsate, but this is
normal.
Braking in Emergencies
ABS allows the driver to steer and
brake at the same time. In many
emergencies, steering can help
more than even the very best
braking.

Driving and Operating 9-41
When StabiliTrak is turned off,
the system will not assist with
directional control of the vehicle
or limit wheel spin. Driving
should be adjusted accordingly.
SeeTraction Control System
(TCS)/StabiliTrak
®Light on
page 5‑23 for more information.
.Press and release the TCS/
StabiliTrak button again to turn
the system back on.
If cruise control is being used when
StabiliTrak activates, cruise control
will automatically disengage. Press
the cruise control button to
reengage when road conditions
allow. See Cruise Control on
page 9‑42 for more information.
Limited-Slip Differential
Vehicles with a limited-slip
differential can give more traction on
snow, mud, ice, sand, or gravel.
It works like a standard differential
most of the time, but when traction
is low, this feature allows the drive
wheel with the most traction to
move the vehicle.
Selective Ride Control
The vehicle may have a ride control
system called Selective Ride
Control. The system provides the
following performance benefits:
.Reduced Impact Harshness
.Improved Road Isolation
.Improved High-Speed Stability
.Improved Handling Response
.Better Control of Body Ride
Motions
To switch from TOUR to SPORT
mode, move the shift lever to the left
while the transmission is in
D (Drive). TOUR:
Use for normal city and
highway driving. This setting
provides a smooth, soft ride.
SPORT: Use where road conditions
or personal preference demand
more control. This setting provides
more “feel,” or response to road
conditions through increased
steering effort and suspension
tuning.
The setting can be changed at any
time. Based on road conditions,
steering wheel angle, and vehicle
speed, the system automatically
adjusts to provide the best handling
while providing a smooth ride. The
TOUR and SPORT modes will feel
similar on a smooth road.

9-42 Driving and Operating
Cruise Control
With cruise control, the vehicle can
maintain a speed of about 40 km/h
(25 mph) or more without keeping
your foot on the accelerator. Cruise
control does not work at speeds
below 40 km/h (25 mph).
On vehicles with the Traction
Control System (TCS) or the
StabiliTrak
®system, it may begin to
limit wheel spin while you are using
cruise control. If this happens, the
cruise control will automatically
disengage. See Traction Control
System (TCS) on page 9‑38 or
StabiliTrak
®System on page 9‑40.
{WARNING
Cruise control can be dangerous
where you cannot drive safely at
a steady speed. So, do not use
the cruise control on winding
roads or in heavy traffic.
Cruise control can be dangerous
on slippery roads. On such roads,
fast changes in tire traction can
cause excessive wheel slip, and
you could lose control. Do not use
cruise control on slippery roads.
The cruise control buttons are
located on the steering wheel.
1(On/Off): Press to turn the
cruise control system on and off. An
indicator light will turn on or off in
the instrument panel cluster.
*(Cancel): Press to disengage
cruise control without erasing the
set speed from memory.
RES/+ (Resume/Accelerate):
Move the thumbwheel up to make
the vehicle resume to a previously
set speed or to accelerate.

Towing
General Towing
Information
Only use towing equipment that has
been designed for the vehicle.
Contact your dealer or trailering
dealer for assistance with preparing
the vehicle for towing a trailer.
See the following trailer towing
information in this section:
.For information on driving while
towing a trailer, see“Driving
Characteristics and
Towing Tips.”
.For maximum vehicle and trailer
weights, see “Trailer Towing.”
.For information on equipment to
tow a trailer, see “Towing
Equipment.”
For information on towing a disabled
vehicle, see Towing the Vehicle on
page 10‑99. For information on
towing the vehicle behind another vehicle such as a motor home, see
Recreational Vehicle Towing on
page 10‑99.
Driving Characteristics
and Towing Tips
{WARNING
The driver can lose control when
pulling a trailer if the correct
equipment is not used or the
vehicle is not driven properly. For
example, if the trailer is too
heavy, the brakes may not work
well
—or even at all. The driver
and passengers could be
seriously injured. The vehicle may
also be damaged; the resulting
repairs would not be covered by
the vehicle warranty. Pull a trailer
only if all the steps in this section
have been followed. Ask your
dealer for advice and information
about towing a trailer with the
vehicle. The vehicle can tow a trailer when
equipped with the proper trailer
towing equipment. For trailering
capacity, see
Trailer Towing (Except
eAssist) on page 9‑61 orTrailer
Towing (eAssist) on page 9‑62.
Trailering changes handling,
acceleration, braking, durability, and
fuel economy. With the added
weight, the engine, transmission,
wheel assemblies, and tires are
forced to work harder and under
greater loads. The trailer also adds
wind resistance, increasing the
pulling requirements. For safe
trailering, correctly use the proper
trailering equipment.
The following information has
important trailering tips and rules for
your safety and that of your
passengers. Read this section
carefully before pulling a trailer.

Driving and Operating 9-59
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 your hand to the right.
Always back up slowly and,
if possible, have someone
guide you.
Making Turns
Notice:Making very sharp turns
while trailering could cause the
trailer to come in contact with the
vehicle. The vehicle could be
damaged. Avoid making very
sharp turns while trailering.
When turning with a trailer, make
wider turns than normal so the
trailer will not strike soft shoulders,
curbs, road signs, trees, or other
objects. Use the turn signal well in
advance and avoid jerky or sudden
maneuvers.
Turn Signals when Towing a
Trailer
The turn signal indicators on the
instrument panel flash whenever
signaling a turn or lane change.
Properly hooked up, the trailer
lamps also flash, telling other
drivers the vehicle is turning,
changing lanes, or stopping.
When towing a trailer, the arrows on
the instrument panel flash for turns
even if the bulbs on the trailer are
burned out. Check occasionally to
be sure the trailer bulbs are still
working.
Driving on Grades
Reduce speed and shift to a lower
gear before starting down a long or
steep downgrade. If the
transmission is not shifted down, the
brakes might have to be used so
much that they would get hot and no
longer work well. The vehicle can tow in D (Drive).
Use a lower gear if the transmission
shifts too often.
When towing at high altitude on
steep uphill grades, engine coolant
boils at a lower temperature than at
normal altitudes. If the engine is
turned off immediately after towing
at high altitude on steep uphill
grades, the vehicle could show
signs similar to engine overheating.
To avoid this, let the engine run
while parked, preferably on level
ground, with the transmission in
P (Park) for a few minutes before
turning the engine off. If the
overheat warning comes on, see
Engine Overheating on page 10‑19.

Engine Oil Life System
When to Change Engine Oil
This vehicle has a computer system
that indicates when to change the
engine oil and filter. This is based
on a combination of factors which
include engine revolutions, engine
temperature, and miles driven.
Based on driving conditions, the
mileage at which an oil change is
indicated can vary considerably. For
the oil life system to work properly,
the system must be reset every time
the oil is changed.
When the system has calculated
that oil life has been diminished, it
indicates that an oil change is
necessary. A CHANGE ENGINE
OIL SOON message comes on. See
Engine Oil Messages on page 5‑38.
Change the oil as soon as possible
within the next 1 000 km (600 mi).It is possible that, if driving under
the best conditions, the oil life
system might 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. Turn the ignition to ON/RUN with
the engine off.
2. Press the DIC MENU button on the turn signal lever to enter the
Vehicle Information Menu. Use
the thumbwheel to scroll through
the menu items until you reach
REMAINING OIL LIFE.
3. Press the SET/CLR button to reset the oil life at 100%.
4. Turn the ignition to LOCK/OFF.
The system is reset when the
CHANGE ENGINE OIL SOON
message is off and the REMAINING
OIL LIFE 100% message is
displayed.
