CAUTION
■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 take unnecessary risks by driving in
dangerous 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
materials trapped or adhering to the underbody, a breakdown or fire could occur.
●When driving off-road or in rugged terr ain, 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.

Example based on your vehicleCargo capacity
Total load capacity
When 2 people with the combined wei ght of 366 lb. (166 kg) are riding
in your vehicle, the available amount of cargo and luggage load capacity
will be as follows:
Vehicles without rear height control air suspension
With third seats — total load capacity: 1315 lb. (595 kg)
1315 lb. - 366 lb. = 949 lb. (595 kg - 166 kg = 429 kg)
Without third seats
— total load capacity: 1525 lb. (690 kg)
1525 lb. - 366 lb. = 1159 lb. (690 kg - 166 kg = 524 kg)
Vehicles with rear height control air suspension
Total load capacity: 1280 lb. (580 kg)
1280 lb. - 366 lb. = 914 lb. (580 kg - 166 kg = 414 kg)
In this condition, if 3 more passengers with the combined weight of 388 lb.
(176 kg) get on, the available cargo and luggage load will be reduced as follows:

2-5. Driving information
GX460_U.S.A. (OM60E69U)Vehicles without rear height control air suspension
With third seats
949 lb. - 388 lb. = 561 lb. (429 kg - 176 kg = 253 kg)
Without third seats
1159 lb. - 388 lb. = 771 lb. (524 kg - 176 kg = 348 kg)
Vehicles with rear height control air suspension
914 lb. - 388 lb. = 526 lb. (414 kg - 176 kg = 238 kg)
As shown in the example above, if
the number of occupants increases,
the cargo and luggage load will be re duced by an amount that equals the
increased weight due to the additional occupants. In other words, if an
increase in the number of occupants ca uses an excess of the total load
capacity (combined weight of occupa nts plus cargo and luggage load),
you must reduce the cargo and luggage on your vehicle.
CAUTION
■Things that must not be carri ed in the luggage compartment
The following things may cause a fire if loaded in the luggage compartment:
●Receptacles containing gasoline
●Aerosol cans

Maintenance and care

■Automatic car washes
●Fold the mirrors back before washing the vehicle. 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 and
harm your vehicle’s paint.
■High pressure car washes
●Do not allow the nozzles of the car wash to come within close proximity of the
windows and the air suspension unit.
●Before using the car wash, check that the fuel filler door on your vehicle is
closed properly.
■Touch-up paint (if equipped)
Touch-up paint may be used to cover small chips or scratches.
Apply the paint soon after the damage occurs or corrosion may set in. To apply the
touch-up paint so it is hardly noticeable, the trick is to apply it only to the bare spots.
Apply only the smallest amount possible and do not paint the surface around the
scratch or chip.
■Aluminum wheels
●Remove any dirt immediately by using a neutral detergent. Do not use hard
brushes or abrasive cleaners. Do not us e strong or harsh chemical cleaners.
Use the same mild detergent and wax as used on the paint.
●Do not use detergent on the wheels when they are hot, for example after driving
for long distance in the hot weather.
●Wash detergent from the wheels immediately after use.
■Bumpers and side moldings
Do not scrub with abrasive cleaners.
