■Additional information for off-road driving
For owners in U.S. mainland, Hawaii and Puerto Rico:

consult the following organizations.
● State and Local Parks and Recreation Departments
● State Motor Vehicle Bureau
● Recreational Vehicle Clubs
● U.S. Forest Service and Bureau of Land Management
WARNING
■Off-road driving precautions
Always observe the following precautions to minimize the risk o f death, seri-
ous 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 espe-
cially 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.
● In a rollover crash, an unbelted person is significantly more l ikely to die
than a person wearing a seat belt. Therefore, the driver and al l passengers
should fasten their seat belts whenever the vehicle is moving.
● When driving off-road or in rugged terrain, do not drive at excessive
speeds, jump, make sharp turns, strike objects, etc. This may c ause loss
of control or vehicle rollover causing death or serious injury. You are also
risking expensive damage to your vehicle’s suspension and chass is.

required to slow the vehicle.
Shift the shift lever to N.
If the shift lever is shifted to N
After slowing down, stop the vehi cle in a safe place by the road.
Stop the engine.
If the shift lever cann ot be shifted to N
Keep depressing the brake pedal with both feet to reduce vehicl e
speed as much as possible.
Stop the engine by turning the
engine switch to the “ACC”

5428-2. Steps to take in an emergency
If a tow truck is not available in an emergency, your vehicle may be
temporarily towed using cables or chains secured to the emergen cy
towing hooks. This should only be attempted on hard surfaced roads
for at most 50 miles (80 km) at under 18 mph (30km/h).
A driver must be in the vehicle to steer and operate the brakes . The
vehicle’s wheels, drive train, a xles, steering and brakes must be in
good condition.
Securely attach cables or chains to the towing hooks.
Take care not to damage the vehicle body.
Enter the vehicle being towed and start the engine.
If the engine does not start, turn the engine switch to the “ON” posi-
tion.
4WD models: Put the front-wheel dr ive control switch in “2WD”.
Shift the shift lever to N and release the parking brake.
When the shift lever cannot be shifted: (P. 200)

WARNING
■If both the ABS and the brake s ystem warning lights remain on
Stop your vehicle in a safe place immediately and contact your To y o t a
dealer. The vehicle will become extremely unstable during braki ng, and the
ABS system may fail, which could cause an accident resulting in death or
serious injury.
■ If the tire pressure warning light comes on
Be sure to observe the following precautions. Failure to do so could cause a
loss of vehicle control and result in death or serious injury.
● Stop your vehicle in a safe place as soon as possible. Adjust the tire infla-
tion pressure immediately.
● If the tire pressure warning light comes on even after tire inf lation pressure
adjustment, it is probable that you have a flat tire. Check the tires. If a tire
is flat, change it with the spare tire and have the flat tire repaired by the
nearest Toyota dealer.
● Avoid abrupt maneuvering and braking. If the vehicle tires deteriorate, you
could lose control of the steering wheel or the brakes.
■ If a blowout or sudden air leakage should occur
The tire pressure warning system may not activate immediately.
■
Maintenance of the tires
Each tire, including the spare (if provided), should be checked monthly
when cold and inflated to the inflation pressure recommended by the
vehicle manufacturer on the vehicle placard or tire inflation p ressure
label (tire and load information label). (If your vehicle has t ires of a dif-
ferent size than the size indica ted on the vehicle placard or tire inflation
pressure label [tire and load information label], you should de termine
the proper tire inflation p ressure for those tires.)
As an added safety feature, your vehicle has been equipped with a tire
pressure monitoring system (TPMS -tire pressure warning system) that
illuminates a low tire pressure telltale (tire pressure warning light) when
one or more of your tires is significantly under-inflated. Acco rdingly,
when the low tire pressure telltale (tire pressure warning ligh t) illumi-
nates, you should stop and check your tires as soon as possible , and
inflate them to the proper pressure. Driving on a significantly under-
inflated tire causes the tire to overheat and can lead to tire failure.
Under-inflation also reduces fuel efficiency and tire tread lif e, and may
affect the vehicle’s handl ing and stopping ability.

WARNING
■Replacing a flat tire
●Observe the following precautions.
Failure to do so may result in serious injury:
• Lower the spare tire completely to the ground before removing it
from under the vehicle.
• Do not try to remove the wheel ornament by hand. Take due care in
handling the ornament to avoi d unexpected personal injury.
• Do not touch the disc wheels or the area around the brakes imm edi-
ately after the vehicle has been driven.
After the vehicle has been driven the disc wheels and the area
around the brakes will be extreme ly hot. Touching these areas with
hands, feet or other body parts while changing a tire, etc., ma y
result in burns.
●Failure to follow these precautions could cause the wheel nuts to
loosen and the t ire to fall off, resulting in death or serious injury.
• Have the wheel nuts tightened with a torque wrench as soon as pos-
sible after changing wheels.
Steel wheel: 154 ft·lbf (209 N·m, 21.3 kgf·m)
Aluminum wheel: 97 ft·lbf (131 N·m, 13.4 kgf·m)
• When installing a tire, only use wheel nuts that have been spe cifi-
cally designed for that wheel.
• Retighten the wheel nuts within 100 miles (160 km) of driving.
• If there are any cracks or defo rmations in the bolt screws, nut
threads or bolt holes of the wheel, have the vehicle inspected by
your Toyota dealer.
• Do not attach a heavily damaged wheel ornament, as it may fly off
the wheel while the vehicle is moving.
• When installing the wheel nuts, b e sure to install them with the
tapered ends facing inward. ( P. 5 1 1 )
