DRIVING TIPS
208
NOTICE
D If driving through water, such as when crossing shallow
streams, first check the depth of the water and the bottom of
the river bed for firmness. Drive slowly and avoid deep water.
D Take all necessary safety measures to ensure that damage to
the engine or other components does not occur.
Water entering the engine air intake will cause severe engine
damage.
Water can wash the grease from wheel bearings, causing
rusting and premature failure, and may also enter the
differentials, transmission and transfer case, reducing the
gear oil’s lubricating qualities.
D Sand and mud that has accumulated in brake drums and
around brake discs may affect braking efficiency and may
damage brake system components.
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 separate ”Owner’s Manual
Supplement/Maintenance Schedule”.
WINTER DRIVING TIPS
Make sure you have ethylene−glycol antifreeze in the radiator.
NOTICE
Do not use alcohol type antifreeze.
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 286
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 263 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 system for loose connections or
obvious damage.
Keep the door locks from freezing.
Squirt lock de−icer or glycerine into the locks to keep them from
freezing.
