CAUTION
nGeneral 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 will hurt or kill you,
your occupants or others.
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.
nGeneral 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
extremely cold temperatures inside the
vehicle can be fatal to children.

2−4. Using other driving systems
Four−wheel drive system
Use the fourwheel drive control sw itch and center differential lock/
unlock switch to select the followin
g transfer and center differential
modes.
nFourwheel drive control switch
“H4” (high speed position)
Normal driving on all types of
roads.
“L4” (low speed position)
Driving requiring maximum
power and traction such as
climbing or descending steep
hills, off−road driving, and hard
pulling in sand or mud, etc.
nCenter differential lock/unlock switch
Lock the center differential
when your vehicle’s wheels
get stuck in a ditch or when
driving on a slippery or bumpy
surface.
Unlock the center differential
after the wheels have been
freed, or after moving to a flat,
non−slippery surface.

nThe fourwheel drive control switch can be operated when
lThe “ENGINE START STOP” switch is in IGNITION ON mode.
lThe shift lever is in the “N” position.
lThe vehicle is stopped completely.
nAdvice for driving on slippery roads in “L4” (low speed position)
lIf you shift the four−wheel drive control switch to “L4” and the shift lever to
the “2” range of “S” while driving in steep off−road areas, the output of the
brake can be controlled effectively by the active traction control system,
which assists the driver to control the driving power of 4 wheels.
lUse the “1” range of “S” of the shift lever for maximum power and traction
when your wheels get stuck or when driving down a steep incline. In the
following cases, the output of the brake can be controlled by the active
traction control system if the engine speed is under 3,000 rpm (normally
under 3,000 rpm when the wheels get unstuck).
The four−wheel drive control switch is in the “L4” position and the shift
lever is in the “1” range of “S” or the shift lever is in “D” or “S” with the
transmission downshifted to first gear.
The four−wheel drive control switch is in the “L4” position and the shift
lever is in the “R” position.
nThe center differential lock/unlock button can be operated when
lThe “ENGINE START STOP” switch is in IGNITION ON mode.
lThe vehicle speed is less than 60 mph (100 km/h).
nLocking/unlocking the center differential
lWhen the center differential is locked, VSC (vehicle stability control) is
automatically turned off. (The center di
fferential lock and “VSC OFF” indi−
cator lights come on.)
lIf the operation is not completed, the center differential lock indicator
blinks. If the indicator light does not turn off when unlocking the center
differential, drive straight ahead while accelerating or decelerating, or
drive in reverse.
lIf the center differential lock/unlock is not completed within 5 seconds
while the cruise control system is on, cancel the cruise control system.

When driving
Crawl control
Allows travel on extremely rough offroad surfaces at a fixed low
speed without pressing the accelerator or brake pedal. Minimizes
loss of traction or vehicle slip wh en driving on slippery road sur
faces, allowing for stable driving.
nCrawl control switch
On/off
The crawl control indicator is lit
and the slip indicator flashes
when operating.
Speed selection switch
Low mode
Effective when traveling on
rocks and pebbles.
*
Medium mode
Effective when traveling on
snow mounds or descending a
slope of rubble.
*
High mode
Effective when ascending a
slope of rubble, or traveling on
snow, dirt, mud, sand, gravel,
grass etc.
*
*
: Depending on the road sur−
face, may not be the most
effective.

When driving
Driving assist systems
To help enhance driving safety a nd 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.
nMulti Terrain ABS (Antilock Brake System)
Restrains the vehicle from slipping when driving on sand, gravel, dirt,
mud, snow, ice or slick road surfaces, or in the event of sudden brak−
ing.
nBrake assist
Generates an increased level of braking force after the brake pedal is
depressed, when the system detects a panic stop situation.
nVSC (Vehicle Stability Control)
Helps the driver to control skidding when swerving suddenly or turning
on slippery road surfaces.
nActive TRAC (Traction Control)
Maintains drive power and prevents the 4 wheels from spinning when
starting the vehicle or accelerating on slippery roads.
nHillstart assist control
Helps prevent the vehicle from rolling backwards when starting on an
incline or slippery slope. It operates for approximately 5 seconds at
maximum.
nKDSS (Kinetic Dynamic Suspension System)
KDSS enhances ride comfort and handling response by using a
hydraulic control system to control the suspension stabilizer bars in
response to road surface and driving conditions during cornering or off−
road driving.

6−1. Specifications

Vehicle specifications
nTreadwear
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.
nTraction 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.
nTemperature 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.
