WARNING
■Off-road driving precautions
Always observe the following precautions to
minimize the risk of death, serious injury
or damage to your vehicle:
●Drive carefully when off the road. Do not ta ke unnecessary risks by driving in danger-
ous places.
●Do not grip the steering wheel spokes when 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 materi-
als trapped or adhering to the underbody, a breakdown or fire could occur.
●When driving off-road or in rugged terrain , do not drive at excessive speeds, jump,
make sharp turns, strike obje cts, etc. This may cause loss of control or vehicle rollover
causing death or serious injury. You are also risking expensive damage to your vehi-
cle’s suspension and chassis.

NOTICE
■To prevent the water damage
Take all necessary safety measures to ensure that water damage 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 damage.
●Water can wash the grease from wheel be arings, causing rusting and premature fail-
ure, and may also enter the differentials, tr ansmission and transfer case, reducing the
gear oil’s lubricating qualities.
■When you drive through water
If driving through water, such as when cro ssing shallow streams, first check the depth of
the water and the bottom of the riverbed for firmness. Drive slowly and avoid deep
water.
■Inspection after off-road driving
●Sand and mud that has accumulated in brake drums and around brake discs may
affect braking efficiency and may damage brake system components.
●Always perform a maintenance inspection afte r each day of off-road driving that has
taken you through rough terrain, sand, mud, or water. For scheduled maintenance
information, refer to the “Warranty and Se rvices Guide”, “Owner’s Manual Supple-
ment” or “Scheduled Maintenance”.

Cleaning and protecting the vehicle exterior
●Working from top to bott
om, liberally apply water to the vehicle body, wheel
wells and underside of the vehicl e to remove any dirt and dust.
●Wash the vehicle body using a sponge or soft cloth, such as a chamois.
●For hard-to-remove marks, use car wa sh soap and rinse thoroughly with
water.
●Wipe away any water.
●Wax the vehicle when the waterproof coating deteriorates.
If water does not bead on a clean surface, apply wax when the vehicle body is cool.
■Automatic car washes
●Fold the mirrors back before washing the ve hicle. Start washing from the front of the
vehicle. Make sure to extend the mirrors before driving.
●Brushes used in automatic car washes may scratch the vehicle surface, parts (wheel,
etc.) and harm your vehicle’s paint.
■High pressure car washes
●As water may enter the cabin, do not bring the nozzle tip near the gaps around the
doors or perimeter of the windows, or spray these areas continuously.
●For vehicles with rear height control air suspension, do not bring the nozzle tip near the
rear air suspension unit.
■Wheels and wheel ornaments
●Remove any dirt immediately by using a neutral detergent.
●Wash detergent off with water immediately after use.
●To protect the paint from damage, make sure to observe the following precautions.
• Do not use acidic, alkaline or abrasive detergent
• Do not use hard brushes
• Do not use detergent on the wheels when they are hot, such as after driving or park- ing in hot weather
■Bumpers and side moldings

NOTICE
■To prevent paint deterioration and corrosion
on the body and components (aluminum
wheels etc.)
●Wash the vehicle immediatel y in the following cases:
• After driving near the sea coast
• After driving on salted roads
• If coal tar or tree sap is present on the paint surface
• If you see dead insects, insect drop pings or bird droppings on the paint
• After driving in an area contaminated wi th soot, oily smoke, mine dust, iron pow-
der or chemical substances
• If the vehicle becomes heavily soiled in dust or mud
• If liquids such as benzene and gasoli ne are spilled on the paint surface
●If the paint is chipped or scratched, have it repaired immediately.
●To prevent the wheels from corroding, remove any dirt and store in a place with low
humidity when storing wheels.
■Cleaning the exterior lights
●Wash carefully. Do not use organic subs tances or scrub with a hard brush.
This may damage the surfaces of the lights.
●Do not apply wax on the surfaces of the lights.
Wax may cause damage to the lenses.
■To prevent damage to the windshield wiper arms
When lifting the wiper arms away from the windshield, pull the driver side wiper arm
upward first, and repeat for the passenger side. When returning the wipers to their
original position, do so from the passenger side first.
■When using an automatic car wash (vehic les with rain-sensing windshield wiper)
Set the wiper switch to the off position.
If the wiper switch is in “AUTO”, the wipers may operate and the wiper blades may be
damaged.
■When using a high pressure car wash
●Do not bring the nozzle tip close to boots (rubber or resin manufactured cover), con-
nectors or the following parts. The parts may be damages if they come into contact
with high-pressure water.
• Traction related parts
• Steering parts
• Suspension parts
•Brake parts
●Keep the cleaning nozzle at least 11.9 in. (30 cm) away from the vehicle body. Other-
wise resin section, such as moldings and bumpers, may be deformed and damaged.
Also, do not continuously hold the nozzle in the same place.
●Do not spray the lower part of the windshield continuously. If water enters the air con-
ditioning system intake located near the lo wer part of the windshield, the air condi-
tioning system may not operate correctly.
●Do not wash the underside of the vehicle using a high pressure car washer.
