DRIVING TIPS
297
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 383 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 (±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 415 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.

Coolant type selection
Use of improper coolants may damage your engine
cooling system. Your coolant must contain
ethylene±glycol type coolant for a proper corrosion
protection of your engine that contains aluminum
components. Use ºToyota Long Life Coolantº or
equivalent.
In addition to preventing freezing and subsequent
damage to the engine, this type of coolant will also
prevent corrosion. Further supplemental inhibitors or
additives are neither needed nor recommended.
Read the coolant container for information on freeze
protection. Follow the manufacturer's directions for how
much to mix with plain water (preferably demineralized
water or distilled water). The total capacity of the cooling
system is given on page 371.
We recommend to use 50% solution for your Lexus, to
provide protection down to about ±35C (±31F). When
it is extremely cold, to provide protection down to about
±50 C (±58F), 60% solution is recommended. Do not
use more than 70% solution for better coolant
performance.

Do not use alcohol type antifreeze or plain water alone.
