DRIVING TIPS
309
Slow down and downshift before descending
steep or long downhill grades. Do not make
sudden downshifts.
 Avoid holding the brake pedal down too long or
too frequently. This could cause the brakes to
overheat and result in reduced braking
efficiency.
HOW TO SAVE FUEL AND
MAKE YOUR VEHICLE LAST
LONGER
Getting more kilometer/mileage from a liter/gallon of fuel
is easy ± just take it easy. It will help make your vehicle
last longer, too. Here are some specific tips on how to
save money on both fuel and repairs:
 Keep your tires inflated at the correct pressure.
Check the pressure every two weeks, or at least once
a month. Underinflation causes tire wear and wastes
fuel.
 Do not carry unneeded weight in your vehicle.
Excess weight puts a heavier load on the engine,
causing greater fuel consumption.
 Avoid lengthy warm±up idling. Once the engine is
running smoothly, begin driving ± but gently.
Remember, however, that on cold winter days this
may take a little longer. 
Accelerate slowly and smoothly. Avoid jackrabbit
starts.
 Avoid long engine idling. If you have a long wait
and you are not in traffic, it is better to turn off the
engine and start again later.
 Avoid engine overrevving . Use a gear position
suitable for the road on which you are traveling.
 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 traffic si gnals
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 needless 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.

DRIVING TIPS
310Improper 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 tuned±up 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 separate ºOwner's
Manual Supplement/Maintenance Scheduleº.)
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.

IF YOUR ENGINE STALLSWHILE DRIVING
If your engine stalls while driving . . . .
1. Reduce your speed gradually, keeping a straight line.
Move cautiously off the road to a safe place.
2. Turn on your emergency flashers.
3. Try starting the engine again.
If the engine will not start, see ºIf your vehicle will not
startº.
CAUTION
If the engine is not running, the power assist for the
brakes and steering will not work, so steering and
braking will be much harder than usual.

IN CASE OF AN EMERGENCY
314
IF YOUR VEHICLE WILL NOTSTART
(a) Simple checks
Before making these checks, make sure you have
followed the correct starting procedure instructions in
ºHow to start the engineº on page 260 and that you have
sufficient fuel. Since your vehicle is equipped with the
engine immobiliser system, also check whether the
other keys will start the engine. If they work, your key
may be broken. Have the key checked at your Lexus
dealer. If none of your keys work, the system is possibly
broken. Call your Lexus dealer. See ºKeysº on page 7.
If the engine is not turning over or is turning over too
slowly ±
1. Check that the battery terminals are tight and clean.
2. If the battery terminals are O.K., switch on the interior
light.
3. If the light is out, dim or goes out when the starter is
cranked, the battery is discharged. You may try jump
starting. See º(c) Jump startingº for further instruction.
If the light is O.K., but the engine still will not start, it
needs adjustment or repair. Call a Lexus dealer,
Roadside Assistance or Customer Service Assistance.
(See ºForewordº.)
NOTICE
Do not pull± or push±start the vehicle. It may damage the vehicle or cause a collision when theengine starts. Also the three±way catalyticconverter / warm up three±way catalytic convertermay overheat and become a fire hazard.
If the engine turns over at its normal speed but will
not start ±
1. The engine may be flooded because of repeated
cranking. See º(b) Starting a flooded engineº for further
instructions.
2. If the engine still will not start, it needs adjustment or
repair. Call a Lexus dealer, Roadside Assistance or
Customer Service Assistance. (See ºForewordº.)

IN CASE OF AN EMERGENCY
315
(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 ºSTARTº 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 ºForewordº.)
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 ºForewordº.).

IN CASE OF AN EMERGENCY
316
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.
