DRIVING TIPS

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
offroad. 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.
 When driving offroad 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.
NOTICE
 If driving through water, such as when crossing
shallow streams, first check the depth of the water
and the bottom of the river bed for firmness. Drive
slowly and avoid deep water.
 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 can wash the grease from wheel bearings,
causing rusting and premature failure, and may also
enter the differentials, transmission and transfer
case, reducing the gear oil’s lubricating qualities.
 Sand and mud that has accumulated in brake drums
and around brake discs may affect braking ef ficiency
and may damage brake system components.

DRIVING TIPS
344
Always perform a maintenance inspection after each
day of offroad driving that has taken you through
rough terrain, sand, mud, or water. For scheduled
maintenance information, refer to the “Owner’s
Manual Supplement / Scheduled Maintenance”.
WINTER DRIVING TIPS
Make sure your coolant is properly protected against
freezing.
Your coolant must contain ethylene −glycol type coolant for a
proper corrosion protection of aluminum components. Use
“Toyota Genuine Long Life Coolant” or equivalent. See
“Checking the engine coolant level” on page 422 for
instructions.
NOTICE
Do not use alcohol type antifreeze or plain water alone.
When it is extremely cold, we recommend to use 60% solution
for your Lexus, to provide protection down to about −50C
(−58 F). Do not use more than 70% solution for better coolant
performance.
Check the condition of the battery and cables.
Cold temperatures reduce the capacity of any battery, so it
must be in top shape to provide enough power for winter
starting. Page 447 tells you how to visually inspect the battery.
Your Lexus dealer and most service stations will be pleased to
check the battery charge level.
Make sure the engine oil viscosity is suitable for the cold
weather.
See page 420 for recommended viscosity. Leaving a heavy
summer oil in your vehicle during winter months may cause
harder starting. If you are not sure about which oil to use, call
your Lexus dealer − they will be pleased to help.

DRIVING TIPS
357

Avoid continuous speeding up and slowing down.
Stop−and−go driving wastes fuel.
 Avoid unnecessary stopping and braking. Maintain a
steady pace. Try to time the traf fic signals so you only need
to stop as little as possible or take advantage of through
streets to avoid traffic lights. Keep a proper distance from
other vehicles to avoid sudden braking. This will also
reduce wear on your brakes.
 Avoid heavy traffic or traffic jams whenever possible.
 Do not rest your foot on the brake pedal. This causes
premature wear, overheating and poor fuel economy.
 Maintain a moderate speed on highways. The faster you
drive, the greater the fuel consumption. By reducing your
speed, you will cut down on fuel consumption.
 Keep the front wheels in proper alignment. Avoid hitting
the curb and slow down on rough roads. Improper
alignment not only causes faster tire wear but also puts an
extra load on the engine, which, in turn, wastes fuel.
 Keep the bottom of your vehicle free from mud, etc. This
not only lessens weight but also helps prevent corrosion. 
Keep your vehicle tunedup and in top shape. A dirty air
cleaner, improper valve clearance, dirty plugs, dirty oil and
grease, brakes not adjusted, etc. all lower engine
performance and contribute to poor fuel economy. For
longer life of all parts and lower operating costs, keep all
maintenance work on schedule, and if you often drive under
severe conditions, see that your vehicle receives more
frequent maintenance. (For scheduled maintenance
information, please refer to the “Owner’s Manual
Supplement / Scheduled Maintenance”.)
CAUTION
Never turn off the engine to coast down hills. Your
power steering and brake booster will not function
without the engine running. Also, the emission control
system operates properly only when the engine is
running.

4. Loosen all the wheel nuts.
Always loosen the wheel nuts before raising the vehicle.
Turn the wheel nuts counterclockwise to loosen them. To get
maximum leverage, fit the wrench to the nut so that the handle
is on the right side, as shown above. Grab the wrench near the
end of the handle and pull up on the handle. Be careful that the
wrench does not slip off the nut.
Do not remove the nuts yet − just unscrew them about one −half
turn.
CAUTION
Never use oil or grease on the bolts or nuts. The nuts
may loose and the wheels may fall off, which could
cause a serious accident.

 Rear (under the rear axle housing)
5. Position the jack at the jack points as shown.
Make sure the jack is positioned on a level and solid surface.

IN CASE OF AN EMERGENCY
372
Before putting on the wheel, remove any corrosion on the
mounting surfaces with a wire brush or such. Installation of
wheels without good metal−to−metal contact at the mounting
surface can cause wheel nuts to loosen and eventually cause
a wheel to come off while driving.8. Reinstall all the wheel nuts finger tight.
Reinstall the wheel nuts and tighten them as much as you can
by hand. Press the tire back and see if you can tighten them
more.
CAUTION
Never use oil or grease on the bolts or nuts. Doing so
may lead to overtightening the nuts and damaging the
bolts. The nuts may loose and the wheels may fall off,
which could cause a serious accident. If there is oil or
grease on any bolt or nut, clean it.

Emergency towing hook precautions:

Before emergency towing, check that the eyelet is not
broken or damaged and that the installation bolts are not
loose.
 Fasten the towing cable or chain securely to the hook.
 Do not jerk the eyelet. Apply steady and even force.
 To avoid damaging the eyelet, do not pull from the side or at
a vertical angle. Always pull straight ahead.
CAUTION
If the emergency towing eyelet is used to get out when
your vehicle becomes stuck in the mud, sand or other
condition from which the vehicle cannot be driven out
under its own power, make sure to observe the
precautions mentioned below. Otherwise, excessive
stress will be put on the eyelet and the towing cable or
chain may break, causing serious injury or damage.
If the towing vehicle can hardly move, do not forcibly
continue the towing. Contact your Lexus dealer or a
commercial tow truck service for assistance.
 Tow the vehicle as straight ahead as possible.
 Keep away from the vehicle during towing.
Tips for towing a stuck vehicle:
The following methods are effective to use when your
vehicle is stuck in the mud, sand or other condition from
which the vehicle cannot be driven out under its own
power. Use extreme caution when towing the vehicle. In
addition, keep away from the vehicles and towing cable or
chain when towing.
 Remove the sand and soil in the front and the back of the
tires.
 Place stones or wood under the tires.
