Winter Driving Tips - Lexus LX 470 Owner's Manual

D Always perform a maintenance inspection after each
day of off−road driving that has taken you through
rough terrain, sand, mud, or water. For scheduled
maintenance information, refer to the "Owner's
Manual Supplement / Scheduled Maintenance".

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
"Toyota Long Life Coolant" or equivalent. See "Checking the
engine coolant level" on page 302 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 324 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 301 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.
