DRIVING TIPS

WINTER DRIVING TIPS

Make sure your coolant is properly protected against
freezing.
Only use "Toyota Super Long Life Coolant" or similar high
quality ethylene glycol based non- silicate, non- amine,
non- nitrite, and non- borate coolant with long- life hybrid
organic acid technology.
See "Checking the engine coolant level" on page 519 for
details of coolant type selection.
"Toyota Super Long Life Coolant" is pre- mixed with 50%
coolant and 50% deionized water. This coolant provides
protection down to about -35_C (-31_F).
NOTICE
Do not use plain water alone.
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 562 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 518 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
your Lexus dealer — they will be pleased to help.
Check the electronic ignition
connections or obvious damage.
Keep the door locks from freezing.
Squirt lock de-icer or glycerine into the locks to keep them from
freezing.
