DRIVING TIPS
406
OFF-ROAD VEHICLE
PRECAUTIONS
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.

IN CASE OF AN EMERGENCY
484
Lexus Link transceiver antenna
The Lexus Link transceiver antenna is removable. Before
taking the vehicle to an automatic car wash, disconnect
the antenna by unscrewing it from the roof mount. When
you remove the antenna, make sure the ignition is turned
off.Use only the supplied or an approved antenna. Unauthorized
antennas, modifications, or attachments could damage the
Lexus Link System and may violate FCC regulations.
CAUTION
Persons who use a medical appliance like a pacemaker
should not touch or come in close contact with the
antenna while the vehicle is ignition on. Otherwise, the
analog cellular signals may produce improper
operation of a medical appliance.
NOTICE
Do not contact with the antenna, this may affect
quality of transceiver's operation and may cause the
unit to operate at a higher power level than needed.
If you forget reattaching the Lexus Link transceiver
antenna, the Lexus Link System may not function
properly.
To prevent damage to the antenna, make sure it is
removed before driving your vehicle through an
automatic car wash.

What about do-it-yourself maintenance?
Many of the maintenance items are easy to do yourself, if you
have a little mechanical ability and a few basic automotive
tools. Simple instructions for how to perform them are
presented in Section 6.
If you are a skilled do-it-yourself mechanic, the Lexus service
manuals are recommended. Please be aware that
do-it-yourself maintenance can affect your warranty
coverage. See your Owner's Guideº, Owner's Manual
Supplementº or Warranty Bookletº for the details.

CAUTION
Make these checks only with adequate ventilation if you
run the engine.
Engine compartment
Items listed below should be checked from time to time,
e.g. each time when refueling.
Washer fluid
Make sure there is sufficient fluid in the tank. See page 572 for
additional information.
Engine coolant level
Make sure the coolant level is between the Fº and Lº lines on
the see-through reservoir when the engine is cold. See page
519 for additional information.
Radiator, condenser and hoses
Check that the front of the radiator and condenser are clean
and not blocked with leaves, dirt, or insects. See page 521 for
