DRIVING TIPS
260

Do not rest your foot on the brake pedal while
driving. It can cause dangerous overheating,
needless wear, and poor fuel economy.

To drive down a long or steep hill, reduce your speed
and downshift. Remember, if you ride the brakes
excessively, they may overheat and not work
properly. See page 234.

Be careful when accelerating, upshifting,
downshifting or braking on a slippery surface. The
abrupt change in engine speed, such as sudden
acceleration or engine braking, could cause the
vehicle to spin or skid.

Do not drive in excess of the speed limit. Even if the
legal speed limit permits it, do not drive over 140
km/h (85 mph) unless your vehicle has high±speed
capability tires. Driving over 140 km/h (85 mph)
may result in tire failure, loss of control and possible
injury. Be sure to consult a tire dealer to determine
whether the tires on your vehicle are high±speed
capability tires or not before driving at such speeds.

Do not continue normal driving when the brakes are
wet. If they are wet, your vehicle will require a
longer stopping distance, and it may pull to one side
when the brakes are applied. Also, the parking
brake will not hold the vehicle securely.WINTER DRIVING TIPS
Make sure you have a proper freeze protection of engine
coolant.
Your coolant must contain ethylene±glycol type coolant for
a proper corrosion protection of aluminum components. Use
ºToyota Long Life Coolantº or equivalent. See ºChecking
the engine coolant levelº on page 347 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
±50 C (±58F). 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 380 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 346 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

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 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 r est your foot on the clutch or brake pedal. This
causes needless wear, overheating and poor fuel economy.

Maintain a m oderate 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 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
