DRIVING TIPS

your Lexus dealer ± they will be pleased to help.
Check
the electronic ignition system for loose connections
or obvious damage.
Keep the door locks from freezing.
Squirt lock de±icer or glycerine into the locks to keep them
from freezing.
Use a washer fluid containing an antifreeze solution.
This product is available at your Lexus dealer and most auto
parts stores. Follow the manufacturer's directions for how
much to mix with water.
NOTICE
Do not use engine antifreeze or any other substitute
because it may damage your vehicle's paint.
Do not use your parking brake when there is a possibility
it could freeze.
When parking, put the transmission into ºPº and block the
front wheels. Do not use the parking brake, or snow or water
accumulated in and around the parking brake mechanism
may freeze the parking brake, making it hard to release.
Keep ice and snow from accumulating under the fenders.
Ice and snow built up under your fenders can make steering
difficult. During bad winter driving, stop and check under the
fenders occasionally. Depending on where you are driving, we recommend you
carry some emergency equipment.
Some of the things you might put in the vehicle are tire chains,
window scraper, bag of sand or salt, flares, small shovel,
jumper cables, etc.
TRAILER TOWING
Your vehicle is designed primarily as a passenger±carrying
vehicle. Towing a trailer will have an adverse effect on
handling, performance, braking, durability and driving
economy (fuel consumption, etc.). Your safety and
satisfaction depend on the proper use of correct equipment
and cautious driving habits. For your safety and the safety of
others, you must not overload your vehicle or trailer. Lexus
warranties do not apply to damage or malfunction caused by
towing a trailer for commercial purposes. Ask your local
Lexus dealer for further details before towing.

DRIVING TIPS
268

Because of the added load of the trailer, your vehicle's
engine may overheat on hot days (at temperatures over
30C [85 F]) when going up a long or steep grade with a
trailer. If the engine coolant temperature gauge indicates
overheating, immediately turn off the air conditioning (if
in use), pull your vehicle off the road and stop in a safe
spot. See ºIf your vehicle overheatsº on page 280 of this
manual.

Always place wheel blocks under both the vehicle and
trailer wheels when parking. Apply the parking brake
firmly. Put the transmission in ºPº. Avoid parking on a
slope with a trailer, but if it cannot be avoided, do so only
after performing the following:
1. Apply the brakes and keep them applied.
2. Have someone place wheel blocks under both the vehicle
and trailer wheels.
3. When the wheel blocks are in place, release your brakes
slowly until the blocks absorb the load.
4. Apply the parking brake firmly.
5. Shift into ºPº and turn off the engine.
When restarting out after parking on a slope:
1. With the transmission in ºPº position, start the engine. Be
sure to keep the brake pedal depressed. 2. Shift into the º3º, º2º, ºLº or ºRº position.
3. Release the parking brake and brake pedal and slowly pull
or back away from the wheel blocks. Stop and apply your
brakes.
4. Have someone retrieve the blocks.

5. Read the following instructions thoroughly.
CAUTION
When jacking, be sure to observe the following to reduce the
possibility of personal injury:

Follow jacking instructions.

Do not put any part of your body under a vehicle supported
by a jack. Personal injury may occur.

Do not start or run the engine while your vehicle is
supported by the jack.

Stop the vehicle on a level firm ground, firmly set the
parking brake and put the transmission in ºPº. Block the
wheel diagonally opposite to the one being changed if
necessary.

IN CASE OF AN EMERGENCY
287
2. Block the wheel diagonally opposite the flat tire to keep
the vehicle from rolling when it is jacked up.
When blocking the wheel, place a wheel block in front of the
front wheels or behind the rear wheels.

IN CASE OF AN EMERGENCY
288
3. Loosen all the wheel nuts.
Always loosen the wheel nuts before raising the vehicle.
Turn the 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.

5. After making sure no one is in the vehicle, raise it high
enough so that the spare tire can be installed.
Allow for the fact that you need more ground clearance when
putting on the spare tire than when removing the flat tire.
To raise the vehicle, insert the jack handle into the jack (it is
a loose fit) and turn it clockwise. As the jack touches the
vehicle and begins to lift, double±check that it is properly
positioned.

IN CASE OF AN EMERGENCY

8. Lower the vehicle completely and tighten the wheel
nuts.
Turn the jack handle counterclockwise to lower the vehicle.
Use only the wheel nut wrench to tighten the nuts. Do not use
other tools or any additional leverage other than your hands,
such as a hammer, pipe or your foot. Make sure the wrench
is securely engaged over the nut.
Tighten each nut a little at a time in the order shown. Repeat
the process until all the nuts are tight.
