DRIVING TIPS
183 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 ”P” 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 passengercarrying 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.
NOTICE
When towing a trailer, be sure to consult your Lexus dealer for
further information on additional requirements.
Weight limits
Before towing, make sure the total trailer weight, gross vehicle
weight, gross axle weight and trailer tongue load are all within
the limits.
The total trailer weight and tongue load can be measured with
platform scales found at a highway weighing station, building
supply company, trucking company, junk yard, etc.

(b) Starting a flooded engine
If the engine will not start, your engine may be flooded because
of repeated cranking.
If this happens, turn the key to ”START” with the accelerator pedal
held down. Continue this operation for 30 seconds and then stop
cranking. Then try starting the engine with your foot off the
accelerator pedal.
If the engine does not start after 30 seconds of cranking, release the
key, wait a few minutes and try again.
If the engine still will not start, it needs adjustment or repair. Call a
Lexus dealer. Roadside Assistance or Customer Service Assistance.
(See ”Foreword”.)
NOTICE
Do not crank for more than 30 seconds at a time. This may
overheat the starter and wiring systems.
(c) Jump starting
To avoid serious personal injury and damage to your vehicle
which might result from battery explosion, acid burns, electrical
burns, or damaged electronic components, these instructions
must be followed precisely.
If you are unsure about how to follow this procedure, we strongly
recommend that you seek help from your Lexus dealer, Roadside
Assistance or Customer Service Assistance. (See ”Foreword”.).
CAUTION
Batteries contain sulfuric acid which is poisonous and
corrosive. Wear protective safety glasses when jump
starting, and avoid spilling acid on your skin, clothing, or
vehicle.
If you should accidentally get acid on yourself or in your
eyes, remove any contaminated clothing and flush the
affected area with water immediately. Then get immediate
medical attention. If possible, continue to apply water with
a sponge or cloth while en route to the medical office.
The gas normally produced by a battery will explode if a
flame or spark is brought near. Use only standardized
jumper cables and do not smoke or light a match while
jump starting.
NOTICE
The battery used for boosting must be 12 V. Do not jump start
unless you are sure that the booster battery is correct.

Booster battery
JUMP STARTING PROCEDURE
1. If the booster battery is installed in another vehicle, make sure the
vehicles are not touching. Turn off all unnecessary lights and
accessories.2. If required, remove all the vent plugs from the booster battery.
Lay a cloth over the open vents on the booster battery. (This helps
reduce the explosion hazard, personal injuries and burns.)
If the booster battery is an extended maintenance interval battery, it
is not necessary to remove the vent plugs.
3. If the engine in the vehicle with the booster battery is not running,
start it and let it run for about 5 minutes. During jump starting, run
the engine at about 2000 rpm with the accelerator pedal lightly
depressed.
4. Locate positive (+) and negative () terminals of each battery.
Connect the jumper cables in the exact order (

)
shown in the illustration.
1
Connect a positive (red) jumper cable clamp to the positive (+)
terminal of the discharged battery.
2
Connect the clamp at the other end of the positive (red) cable
to the positive (+) terminal of the booster battery.
3
Connect a negative (black) cable clamp to the negative ()
terminal of the booster battery.
4
Connect the clamp at the other end of the negative (black) cable
to a solid, stationary, unpainted metallic point (e.g. engine
hanger) away from the battery. Do not connect it to or near any
part that moves when the engine is cranked.

IN CASE OF AN EMERGENCY
196
CAUTION
When making the connections, to avoid serious injury, do not
lean over the battery or accidentally let the jumper cables or
clamps touch anything except the correct battery terminals or
the ground.
5. Start your engine in the normal way. After starting, run it at about
2000 rpm for several minutes with the accelerator pedal lightly
depressed.
6. Carefully disconnect the cables in the exact reverse order: the
negative cable and then the positive cable.
7. Carefully dispose of the battery cover cloths which may now
contain sulfuric acid.
8. If removed, replace all the battery vent plugs.
If the cause of your battery discharging is not apparent (for example,
lights left on), you should have it checked.
IF YOUR VEHICLE OVERHEATS
If your engine coolant temperature gauge indicates overheating,
if you experience a loss of power, or if you hear a loud knocking
or pinging noise, the engine has probably overheated.
When the engine overheats
Pull safely off the road, stop the vehicle and turn on your emergency
flashers. Put the transmission in ”P” and apply the parking brake.
A: If steam is coming from your engine:
Turn off the engine. Leave the hood closed until there is no sign of
steam or coolant. Your engine could have been seriously damaged
already. Call your Lexus dealer for assistance.
CAUTION
To help avoid personal injury, keep the hood closed until there
is no steam. Escaping steam or coolant is sign of very high
pressure.
