with the AWD system.
●Blinks when the differential
temperature is too high.
●Stays on constantly - The engine drives
the front wheels only in this state. Have your
vehicle checked by a dealer.
●Blinks while driving - The engine drives
only the front wheels in this state. Stop in a

uuOff-Highway Driving Guidelines uAvoiding Trouble
Driving
Avoiding Trouble
• Check Out Your Vehicle before you leave the pavement and make sure that all
scheduled maintenance has been comple ted. Pay special attention to the
condition of the tires, an d check the tire pressures.
• Remember the route you choose presents limits (too steep or bumpy), you have
limits (driving skill and comfort), and your ve hicle has limits (traction, stability, and
power). Failing to recognize these limits will likely put you and your passengers in
a hazardous situation.
• Accelerating and Braking should be done slowly and gradually. Trying to start
or stop too fast can cause a loss of traction and you could lose control.
• Avoiding Obstacles and Debris in the road reduces the likelihood of a rollover
or damage to your suspension or other components.
• Driving on Slopes increases your risk of a rollover, particularly if you attempt to
drive across a slope that is too steep. Going straight up or down a slope is usually
the safest. If you can’t clearly see all cond itions or obstacles on a slope, walk it
before you drive it. If there is any doubt whether you can safely pass, don’t try it.
Find another route. If you get stuck when climbing, do not try to turn around.
Back down slowly following the same route you took up the hill.
• Crossing a Stream - Avoid driving through deep water. If you encounter water
in your route (a small stream or large pu ddle, for example), evaluate it carefully
before going ahead. Make sure it is shallow, flowing slowly, and has firm ground
underneath. If you are not sure of the depth or the ground, turn around and find
another route. Driving through deep water can also damage your vehicle. The
water can get into the transmission and differential, diluting the lubricant and
causing an eventual failure. It can also wash the grease out of the wheel bearings.
• If You Get Stuck, carefully go in the direction that you think will get you
unstuck. Do not spin the tires as this will only make things worse and could
damage the transmission. If you are unable to free yourself, your vehicle will need
to be towed. Front and rear tow hooks are provided for this purpose.

uuWhen Driving uIntelligent Variable Torque Management (i-VTM4TM) AWD System*
Driving
Intelligent Variable Torque Management (i-VTM4TM)
AWD System*
The Intelligent Variable To rque Management (i-VTM4TM) AWD System is a full time
all wheel drive system that automatically controls and transfers varying amount of
engine torque to all wheels independently according to the driving conditions.
You still need to exercise the same care when accelerating, steering, and braking
that you would in a two wheel drive vehicle.
Avoid continuously driving on slippery surfaces where a wheel is likely to spin out,
and do not drive if the All-wheel drive ( AWD) Indicator starts blinking. Driving
continuously under such conditions can damage the system’s torque distribution
unit.
If the All-wheel drive (AWD ) Indicator blinks while driving, it indicates the
differential temperature is too high. If this happens, pull to the side of the road
when it is safe, shift to park, and idle the engine until the indicator goes out. If the
indicator does not go out, take your vehi cle to a dealer to have it checked.1Intelligent Variable Torq ue Management (i-VTM4TM) AWD
System*
NOTICE
Do not continuously spin the front tires of your
vehicle. Continuously spinning the front tires can
cause transmission or re ar differential damage.
The Intelligent Variable Torque Management (i-
VTM4
TM) AWD System may not function properly if
tire type and size are mixed. Make sure to use the
same size and type of tire , and the air pressures as
specified. 2 Tire and Wheel Replacement P. 522

*1: If the message Maintenance Due Now does not appear more than 12 months after the display
is reset, change the engine oil every year.
# : See information on maintenance and emissions warranty in the first column on page 581.
*2: If you drive in dusty conditions, replace the air cleaner element every 15,000 miles (24,000 km).
*3: If you drive primarily in urban areas that have high concentrations of soot in the air from industry and from diesel-powered vehicles, replace every 15,000 miles (24,000 km).

●Replace engine oil*1
B●Replace engine oil*1 and oil filter●Inspect front and rear brakes●Check parking brake adjustment●Inspect tie rod ends, steering gearbox, and boots●Inspect suspension components●Inspect driveshaft boots●Inspect brake hoses and lines (Including ABS/VSA ®)●Inspect all fluid levels and condition of fluids●Inspect exhaust system#
●Inspect fuel lines and connections#
*4: Driving in mountainous areas at very low vehicle speeds or trailer towing results in higher transmission
temperatures. This requires transmission fluid changes more frequently than recommended by the
Maintenance Minder
TM. If you regularly drive your vehicle under these conditions, have the transmission
fluid changed at every 30,000 miles (48,000 km) or 2 years.
*5: If you drive regularly in very high temperatures (over 110°F, 43°C), in very low temperatures (under
-20°F, -29°C), or towing a trailer, replace every 60,000 miles (U.S.) / 100,000 km (Canada).
*6: Driving in mountainous areas at very low vehicle speeds or trailer towing results in higher level of mechanical (Shear) stress to fluid. This requires differential fluid changes more frequently than
recommended by the Maintenance Minder
TM. If you regularly drive your vehicle under these conditions,
have the differential fluid changed at 7,500 miles (12,000 km), then every 15,000 miles (24,000 km).
