CAUTION
■General precautions while driving
Driving under the influence: Never drive your vehicle when under the influ-
ence of alcohol or drugs that have impaired your ability to operate your vehi-
cle. Alcohol and certain drugs delay reaction time, impair judgment and
reduce coordination, which could lead to an accident that could result in
death or serious injury.
Defensive driving: Always drive defensively. Anticipate mistakes that other
drivers or pedestrians might make and be ready to avoid accidents.
Driver distraction: Always give your full attention to driving. Anything that dis-
tracts the driver, such as adjusting controls, talking on a cellular phone or
reading can result in a collision with resulting death or serious injury to you,
your occupants or others.
■ General precaution regarding children’s safety
Never leave children unattended in the vehicle, and never allow children to
have or use the key.
Children may be able to start the vehicle or shift the vehicle into neutral.
There is also a danger that children may injure themselves by playing with
the cigarette lighter, the windows, the moon roof, or other features of the
vehicle. In addition, heat build-up or ex tremely cold temperatures inside the
vehicle can be fatal to children.

When driving
Four-wheel drive system
: If equipped
Use the front wheel drive control switch to select the following trans-
fer modes.
*1: Vehicles with multi-information display
*2: Vehicles without multi-information display
2WD (high speed position, two-wheel drive)
Normal driving.
4H (high speed position, four-wheel drive)
Greater traction than two wheel drive.
When you experience a loss of power, such as wheel slipping.
The 4HI indicator comes on.
4L (low speed position, four-wheel drive)
Driving requiring maximum power and traction such as climbing or
descending steep hills, off-road driving and hard pulling in sand or mud,
etc.
The 4LO indicator comes on.
*2*1

2-4. Using other driving systems
AUTO LSD system
The AUTO LSD system aids traction by using the traction control
system to control engine performance and braking when one of the
rear wheels begins to spin.
The system should be used only wh en one of the rear wheels spin-
ning occurs in a ditch or rough surface.
■ System operation
The system can be used on 2W D models and in 2WD mode on
4WD models.
The system is activated when dr iving at a speed under 62 mph
(100 km/h).
The AUTO LSD system will be ac tivated with the following two
procedures.
Press the VSC OFF switch
briefly.
At this time, the AUTO LSD
indicator will come on.
To turn off the system, push
the switch again.
Stop the vehicle completely,
and press the VSC OFF
switch for more than 3 sec-
onds.
At this time, VSC OFF and
AUTO LSD indicators will
come on simultaneously.
To turn off the system, push
the switch again.

2-4. Using other driving systems
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 h eavily 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.
■Trailer Sway Control
Helps the driver to control trailer sway by selectively applying brake
pressure for individual wheels and reducing engine torque when trailer
sway is detected.
Trailer Sway Control is part of the VSC system and will not operate if
VSC is turned off or experiences a malfunction.
■ TRAC (Traction Control) for 2WD
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
Maintains drive power and prevents all wheels from spinning when
starting the vehicle or accelerating on slippery roads.

Vehicle specifications
■
Treadwear
The treadwear grade is a comparative rating based on the wear
rate of the tire when tested under controlled conditions on a speci-
fied government test course.
For example, a tire graded 150 would wear one and a half (1 - 1/2)
times as well on the government course as a tire graded 100.
The relative performance of tires depends upon the actual conditions
of their use, however, and may depart significantly from the norm due
to variations in driving habits, service practices and differences in
road characteristics and climate.
■ Traction AA, A, B, C
The traction grades, from highest to lowest, are AA, A, B and C,
and they represent the tire’s ab ility to stop on wet pavement as
measured under controlled cond itions on specified government
test surfaces of asphalt and concrete.
A tire marked C may have poor traction performance.
Warning: The traction grade assigned to this tire is based on braking
(straight ahead) traction tests and does not include cornering (turn-
ing) traction.
■ Temperature A, B, C
The temperature grades are A (the highest), B, and C, represent-
ing the tire’s resistance to the generation of heat and its ability to
dissipate heat when tested under controlled conditions on a speci-
fied indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to
degenerate and reduce tire life, and excessive temperature can lead
to sudden tire failure.
The grade C corresponds to a level of performance which all passen-
ger car tires must meet under the Federal Motor Vehicle Safety Stan-
dard No. 109.
Grades B and A represent higher levels of performance on the labo-
ratory test wheel than the minimum required by law.
