OFF-ROAD VEHICLEPRECAUTIONS
This vehicle belongs to the utility vehicle class, which has
higher ground clearance and narrower tread in relation to
the height of its center of gravity to make it capable of
performing in a wide variety of off-road applications.
Specific design characteristics give it a higher center of
gravity than ordinary passenger cars. This vehicle design
feature causes this type of vehicle to be more likely to
rollover. And, utility vehicles have a significantly higher
rollover rate than other types of vehicles. An advantage
of the higher ground clearance is a better view of the road
allowing you to anticipate problems. It is not designed for
cornering at the same speeds as ordinary passenger cars
any more than low-slung sports cars designed to perform
satisfactorily under off-road conditions. Therefore, sharp
turns at excessive speeds may cause rollover.
CAUTION
Always observe the following precautions to minimize
the risk of serious personal injury or damage to your
vehicle:
 In a rollover crash, an unbelted person is
significantly more likely to die than a person wearing
a seat belt. Therefore, the driver and all passengers
should fasten their seat belts whenever the vehicle is
moving.
 Avoid sharp turns or abrupt maneuvers, if at all
possible. Failure to operate this vehicle correctly
may result in loss of control or vehicle rollover
causing death or serious injury.
 Loading cargo on the roof luggage carrier will make
the center of the vehicle gravity higher. Avoid high
speeds, sudden starts, sharp turns, sudden braking
or abrupt maneuvers, otherwise it may result in loss
of control or vehicle rollover due to failure to operate
this vehicle correctly.
 Always slow down in gusty crosswinds. Because of
its profile and higher center of gravity, your vehicle is
more sensitive to side winds than an ordinary
passenger car. Slowing down will allow you to have
better control.

DRIVING TIPS
448
When driving off-road or in rugged terrain, do not
drive at excessive speeds, jump, make sharp turns,
strike objects, etc. This may cause loss of control or
vehicle rollover causing death or serious injury. You
are also risking expensive damage to your vehicle's
suspension and chassis.
 Do not drive horizontally across steep slopes.
Driving straight up or straight down is preferred.
Your vehicle (or any similar off-road vehicle) can tip
over sideways much more easily than forward or
backward.BREAK-IN PERIOD
Drive gently and avoid high speeds.
You need not follow a break-in schedule with your new Lexus.
But following a few simple tips for the first 1600 km (1000 miles)
can add to the future economy and long life of your vehicle:
Avoid full throttle acceleration when starting and driving.
 Avoid racing the engine.
 Try to avoid hard stops during the first 300 km (200 miles).
 Do not drive for a long time at any single speed, either fast
or slow.
 Do not tow a trailer during the first 800 km (500 miles).

DRIVING TIPS
449
OPERATION IN FOREIGNCOUNTRIES
If you plan to drive your Lexus in another country...
First, comply with the vehicle registration laws.
Second, confirm the availability of the correct fuel (unleaded
and minimum octane rating).
TIPS FOR DRIVING IN VARIOUS CONDITIONS
Always slow down in gusty crosswinds. This will allow you
much better control.
 Drive slowly onto curbs and, if possible, at a right angle.
Avoid driving onto high, sharp-edged objects and other
road hazards. Failure to do so can lead to severe tire
damage such as a tire burst.
Drive slowly when passing over bumps or travelling on a
bumpy road. Otherwise, the impact could cause severe
damage to the tires and/or wheels.
 When parking on a hill, turn the front wheels until they touch
the curb so that the vehicle will not roll. Apply the parking
brake, and place the transmission in Pº. If necessary, block
the wheels.
 Washing your vehicle or driving through deep water may get
the brakes wet. To see whether they are wet, check that
there is no traffic near you and then press the pedal lightly.
If you do not feel a normal braking force, the brakes are
probably w et. To dry them, drive the vehicle cautiously while
lightly pressing the brake pedal with the parking brake
applied. If they still do not work safely, pull to the side of the
road and call a Lexus dealer for assistance.

DRIVING TIPS
450
CAUTION
Before driving off, make sure the parking brake is
fully released and that the parking brake reminder
light is off.
 Do not leave your vehicle unattended while the
engine is running.
 Do not rest your foot on the brake pedal while driving.
It can cause dangerous overheating, needless wear,
and poor fuel economy.
 To drive down a long or steep hill, reduce your speed
and downshift. Remember, if you ride the brakes
excessively, they may overheat and not work
properly. See page 395.
 Be careful when accelerating, upshifting,
downshifting or braking on a slippery surface. The
abrupt change in engine speed, such as sudden
acceleration or engine braking, could cause the
vehicle to skid or spin.
 Do not drive in excess of the speed limit. Even if the
legal speed limit permits it, do not drive over 140 km/h
(85 mph) unless your vehicle has high-speed
capability tires. Driving over 140 km/h (85 mph) may
result in tire failure, loss of control and possible
injury. Be sure to consult a tire dealer to determine
whether the tires on your vehicle are high-speed
capability tires or not before driving at such speeds.

DRIVING TIPS
451
Do not continue normal driving when the brakes are
wet. If they are wet, your vehicle will require a longer
stopping distance, and it may pull to one side when
the brakes are applied. Also, the parking brake will
not hold the vehicle securely.
 If you drive through deep water over about 500 mm
(20 in.) in depth, put the vehicle height in the HI (High)
mode with the active height select switch and then
turn off the active height control suspension by
pushing the height control switch. Drive your vehicle
at 30 km/h (19 mph) or lower speed.

OFF-ROAD DRIVINGPRECAUTIONS
When driving your vehicle off-road, please observe the
following precautions to ensure your driving enjoyment and to
help prevent the closure of areas to off-road vehicles.
a. Drive your vehicle only in areas where of f-road vehicles are
permitted to travel.
b. Respect private property. Get owner's permission before
entering private property.
c. Do not enter areas that are closed. Honor gates, barriers
and signs that restrict travel.
d. Stay on established roads. When conditions are wet,
driving techniques should be changed or travel delayed to
prevent damage to roads.
For owners in U.S. mainland, Hawaii and Puerto Rico:
To obtain additional information pertaining to driving your
vehicle off-road, 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
CAUTION
Always observe the following precautions to minimize
the risk of serious personal 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.
 In a rollover crash, an unbelted person is
significantly more likely to die than a person wearing
a seat belt. Therefore, the driver and all passengers
should fasten their seat belts whenever the vehicle is
moving.

DRIVING TIPS
453
When driving off-road or in rugged terrain, do not
drive at excessive speeds, jump, make sharp turns,
strike objects, etc. This may cause loss of control or
vehicle rollover causing death or serious injury. You
are also risking expensive damage to your vehicle's
suspension and chassis.
