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 vehicle 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 uSuper Handling-All Wheel DriveTM (SH-AWD ®)*
Driving
Super Handling-All Wheel DriveTM (SH-AWD ®)*
The system controls and trans fers varying amounts of engine torque to each wheel
in accordance with the driving conditions.
SH-AWD ® helps to enhance driving stability, and lets you handle situations like
slippery surfaces, such as snow, sand, mud, and steep hill, better than when driving
with two wheel drive. However, the system does not help to enhance braking. Be
precautious about the following:
• It is still your responsibility to drive sa fely when you steer, accelerate, and apply
brakes.
• Leave a sufficient margin when braking on slippery surfaces.1Super Handling-All Wheel DriveTM (SH-AWD ®)*
The SH-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. 566
Do not continuously spin the front tires of your
vehicle. Continuously spinning the front tires can
cause damage to the transmission and SH-AWD ®
unit.
If the Super Handling-All Wheel Drive
TM (SH-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, change the
gear position to
( P, and idle the engine until the
indicator goes out.

U.S. models
*1: If a Maintenance Minder Indicator and message 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.
*2: If you drive in dusty conditions, replace the air cleaner element 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 expiration date for Temporary Tire Repair Kit bottle (If
equipped)
●Inspect tie rod ends, steering gearbox, and boots●Inspect suspension components●Inspect driveshaft boots●Inspect brake hoses and lin es (Including ABS/VSA®)●Inspect all fluid levels and condition of fluids●Inspect exhaust system#
●Inspect fuel lines and connections#*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 the dust and pollen filter every 15,000 miles (24,000 km).
*4: 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. 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).
*5: If a Maintenance Minder Indicator does not appear more than 36 months after the display for item 7 is reset, change the brake fluid every 3 years.
