When driving
Driving assist systems
To help enhance driving safety and performance, the following sys-
tems operate automatically in res ponse to various driving situations.
Be aware, however, that these systems are supplementary and
should not be relied upon too heavi ly when operating the vehicle.
■ABS (Anti-lock Brake System)
Helps to prevent wheel lock when the brakes are applied suddenly, or if
the brakes are applied while driving on a slippery road surface.
■Brake Assist
Generates an increased level of braking force after the brake pedal is
depressed, when the system detects a panic stop situation.
■VSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning
on slippery road surfaces.
■TRAC (Traction Control) for 2WD models and 2WD mode on
4WD models
Maintains drive power and prevents the rear wheels from spinning
when starting the vehicle or accelerating on slippery roads.
■A-TRAC (Active Traction Control) for 4WD mode on 4WD
models
Maintains drive power and prevents the all wheels from spinning when
starting the vehicle or accelerating on slippery roads.

When driving
To disable A-TRAC (4L mode on 4WD models)
If the vehicle gets stuck in fresh snow or mud, A-TRAC may reduce
power from the engine to the wheels. You may need to turn the sys-
tem off to enable you to rock the vehicle in order to free it. Stop the vehicle completely, and
press the VSC OFF switch for
more than 3 seconds.
The TRAC OFF indicators will
come on.
Push the switch again to turn the
system back on.
■Automatic reactivation of TRAC, A-TRAC and VSC
Turning the engine switch off after turning off the TRAC, A-TRAC and VSC
systems will automatically re-enable them.
■ Sounds and vibrations caused by the ABS, TRAC, A-TRAC, VSC and
brake assist system
●A sound may be heard from the engine compartment when the engine is
started and just after the vehicle begins to move. This sound does not
indicate that a malfunction has occurred in any of these systems.
● Any of the following conditions may occur when the above systems are
operating. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
■ If the brake system overheats
TRAC or A-TRAC will cease operation and a buzzer will sound to alert the
driver. The TRAC OFF indicator will come on. Stop the vehicle in a safe
place. (There is no problem with continuing normal driving.)
■ Shifting to 4L
VSC is automatically turned off.

278 2-5. Driving information
Trailer towing tipsYour vehicle will handle differently when towing a trailer. The three
main causes of vehicle-trailer ac cidents are driver error, excessive
speed and improper trailer loading. Keep the following in mind when
towing.
● Speed limits for towing a trailer vary by state or province. Do not
exceed the posted towing speed limit.
● Before starting out, check the trailer’s light and the vehicle-trailer
connections. Recheck after driving a short distance.
● Practice turning, stopping and reve rsing with the trailer attached in
an area away from traffic until you become accustomed to the feel
of the vehicle.
● Reversing with a trailer attached is difficult and requires practice.
Grip the bottom of the steering wheel and move your hand to the
left to move the trailer to the left. Move your hand to the right to
move the trailer to the right. (This is generally opposite to reversing
without a trailer attached.) Avoid sharp or prolonged turning. Have
someone guide you when reversing to reduce the risk of an acci-
dent.
● As stopping distance is increased when towing a trailer, vehicle-to-
vehicle distance should be increased. For each 10 mph (16 km/h)
of speed, allow at least o ne vehicle and trailer length.
● Avoid sudden braking as you may skid, resulting in jackknifing and
loss of control. This is especiall y true on wet or slippery surfaces.
● Avoid jerky starts or sudden acceleration.
● Avoid jerky steering and sharp turns, and slow down before mak-
ing a turn.
● Note that when making a turn, th e trailer wheels will be closer than
the vehicle wheels to the inside of the turn. Compensate by making
a larger than normal turning radius.

280 2-5. Driving information
Shift into P and turn off the engine.
● When restarting after parking on a slope:
With the transmission in P, start the engine. Be sure to keep
the brake pedal pressed.
Shift into D or R (if reversing).
Release the parking brake and brake pedal, and slowly pull or
back away from the wheel blocks. Stop and apply the brakes.
Have someone retrieve the blocks.
■Service connector for towing br ake controller (with towing package)
■ Matching trailer ball height to trailer coupler height
Your vehicle is equipped with a service
connector for the trailer brake controller
as shown.
Access the service connector.
Remove the scuff plate.
Remove the clip (screw type)
and trim board.
Remove the connector cover.
No matter which class of tow hitch
applies, for a safe trailer hookup, the
trailer ball setup on must be the proper
height for the coupler on the trailer.

296 3-1. Using the air conditioning system and defogger
■Air conditioning odors
●During use, various odors from inside and outside the vehicle may enter
into and accumulate in the air conditioning system. This may then cause
odor to be emitted from the vents.
● To reduce potential odors from occurring:
• It is recommended that the air conditioning system be set to outside air
mode prior to turning the vehicle off.
• The start timing of the blower may be delayed for a short period of time immediately after the air conditioning system is started in automatic
mode.
CAUTION
■ To prevent the windshield from fogging up
Do not use during cool air operation in extremely humid weather. The
difference between the temperature of the outside air and that of the wind-
shield can cause the outer surface of the windshield to fog up, blocking your
vision.
NOTICE
■To prevent battery discharge
Do not leave the air conditioning system on longer than necessary when the
engine is stopped.
