2-1. Driving procedures

When driving
CAUTION
■When driving the vehicle
●Use engine braking (downshift) to maintain a safe speed when driving down a
steep hill.
Using the brakes continuously may cause the brakes to overheat and lose effec-
tiveness. (P. 9 9 )
●When stopped on an inclined surface, use the brake pedal and parking brake to
prevent the vehicle from rolling backward or forward and causing an accident.
●Be careful when driving on slippery surfaces, as the vehicle may spin or skid when
downshifting, rapidly accelerating, braking or turning.
●Do not adjust the position of the steering wheel, the seat, or the inside or outside
rear view mirrors while driving.
Doing so may result in a loss of vehicle control that can cause accidents that may
result in death or serious injury.
●Always check that all passengers' arms, heads or other parts of their bodies are
not outside the vehicle, as this may result in death or serious injury.
●Do not drive in excess of the speed limit. Even if the legal speed limit permits it, do
not drive over 85 mph (140 km/h) unless your vehicle has high-speed capability
tires. Driving over 85 mph (140 km/h) may result in tire failure, loss of control and
possible injury. Be sure to consult a tire dealer to determine whether the tires on
your vehicle are high-speed capability tires or not before driving at such speeds.
●If you drive through deep water over ab out 500 mm (20 in.) in depth, put the
vehicle height in the HI (High) mode with the active height select switch and then
turn off the active height control suspension by pushing the height control switch.
Drive your vehicle at 30 km/h (19 mph) or lower speed.

2-4. Using other driving systems
AHC (Active Height Control Suspension)
AHC adjusts the vehicle height in accordance with driving conditions.
There are 3 selectable modes, “HI” (high), “N” (normal), and “LO” (low).
■Height control switch
“▲ ” (Up) switch
“ ▼ ” (Down) switch
“OFF” switch
Push while the vehicle is
stopped. The “OFF” indicator
light will come on, and the vehi-
cle height will be fixed in the
current mode. Push the switch
again to turn the system back
on.

When driving
■Extra high mode
If the vehicle becomes stuck, extra high mode may be automatically selected when
the vehicle height is in high mode with the four-wheel drive control lever in the “L”
position.
The vehicle height is raised to 2.8 in. (70 mm) higher than the normal mode height,
or slightly higher.
Extra high mode will change back to high mode when:
• The vehicle is no longer stuck
• The four-wheel drive control lever is shifted to a position other than “L”
●If you push “ ▼” when in extra high mode, normal mode is selected.
●Extra high mode cannot be manually selected.
■Turning off the active height control suspension
●The system will remain off until the switch is pushed again, even if the ignition is
turned off.
●Even if AHC is turned off, the system automatically selects the normal mode if
the vehicle's speed exceeds 19 mph (30 km/h).
■Automatic leveling function
The vehicle is adjusted to a fixed height for each mode, regardless of the number of
occupants and the luggage load.
●However the vehicle cannot be raised if the vehicle load exceeds the following
limits:
• Up to 4 occupants* plus approximately 661 lb. (300 kg) in the normal mode
• Up to 4 occupants* plus approximatel y 375 lb. (170 kg) in the high mode
*: average weight 150 lb. (68 kg) per person
●If the vehicle height cannot be raised when in the normal mode, and “LO” is lit
on the height mode indicator, the vehicle is loaded too heavily. Take extra care
when driving in this condition.
If the vehicle height cannot be raised even after unloading the vehicle, press
“ ▼ ” then “ ▲” on the height mode select switch. If the vehicle height still cannot
be raised, turn the ignition off th en on again, then try once more.

134
2-4. Using other driving systems
■If the vehicle height does not change
If the vehicle is loaded too heavily, or the undercarriage has come into contact with
the road surface, the vehicle height cannot be raised/lowered. In this case, the indi-
cator lights will change as follows:
●The current mode indicator light will turn off, and the target mode indicator light
will begin flashing.
●The target mode indicator light will turn off, and the original mode indicator light
will be lit once more. (The vehicle height does not change.)
■In the following cases AHC will not operate
●The brake pedal has been depressed for longer than 5 seconds while the vehi-
cle is stopped.
●The suspension fluid temperature is lower than -22°F (-30°C).
●Driving on bumpy roads which may cause the suspension to fully elongate.
●If the steering wheel is abruptly turned more than 3/4 of a revolution with the
center differential lock system activated.
■Cold weather operation
It may take longer for the vehicle height to change if the suspension fluid tempera-
ture drops below -5°F (-15°C).
AHC does not operate when the suspension fluid temperature drops below -22°F
(-30°C).
●In this case, the selected height mode indicator light will flash when the height
mode select switch is pressed, however the vehicle height will not change.
Once the engine has warmed the suspension fluid to within normal operating
limits, AHC will begin operating and the vehicle height will automatically
change to the selected mode.
●When the suspension fluid is around -22°F (-30°C), the vehicle height may not
be able to be raised, even if AHC is operating. In this case, push “ ▼” then “▲ ”
on the height mode select switch after further warming the engine to select the
desired vehicle height.

2-4. Using other driving systems
AVS (Adaptive Variable Suspension)
■Driving mode
●Mode is suitable for ordinary driving.
●Mode or is suitable for heavy load or driving on a unpaved road.
●With the four-wheel drive control lever at “L”, the damping effect suitable for off-
road driving will be provided.
AVS controls the suspension according to the road and driving conditions.
Selecting an optimum driving mode allows good riding comfort and stabil-
ity.
For driving on a bumpy road
For ordinary driving such as
in the city traffic
For moderate high speed
driving
For sporty type driving such
as on winding mountain
roads and high speed driving

When driving
CAUTION
■Off-road driving precautions
Always observe the following precautions to help minimize the risk of serious per-
sonal injury or damage to your vehicle:
●Drive carefully when off the road. Do not take unnecessary risks by driving in
dangerous places.
●Do not grip the steering wheel spokes wh en driving off-road. A bad bump could
jerk the wheel and injure your hands. Keep both hands and especially your
thumbs on the outside of the rim.
●Always check your brakes for effectiveness immediately after driving in sand,
mud, water or snow.
●After driving through tall grass, mud, rock, sand, rivers, etc., check that there is no
grass, bush, paper, rags, stone, sand, etc. adhering or trapped on the underbody.
Clear off any such matter from the underbody. If the vehicle is used with these
materials trapped or adhering to the underbody, a breakdown or fire could occur.
●When driving off-road or in rugged te rrain, do not drive at excessive speeds,
jump, make sharp turns, strike objects, etc. This may cause loss of control or vehi-
cle rollover causing death or serious injury. You are also risking expensive dam-
age to your vehicle’s suspension and chassis.
NOTICE
■To prevent the water damage
Take all necessary safety measures to ensure that water dama ge to the engine or
other components does not occur.
●Water entering the engine air intake will cause severe engine damage.
●Water entering the automatic transmission will cause deterioration in shift quality,
locking up of your transmission accompanied by vibration, and ultimately dam-
age.
●Water can wash the grease from wheel bearings, causing rusting and premature
failure, and may also enter the differentials, transmission and transfer case, reduc-
ing the gear oil’s lubricating qualities.
