DRIVING TIPS
334See page 416 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.
Use a washer fluid containing an antifreeze solution.
This product is available at your Lexus dealer and most
auto parts stores. Follow the manufacturer's directions
for how much to mix with water.
NOTICE
Do not use engine antifreeze or any other
substitute because it may damage your vehicle'spaint.
Do not use your parking brake when there is a
possibility it could freeze.
When parking, put the transmission into ºPº and block
the front wheels. Do not use the parking brake, or snow
or water accumulated in and around the parking brake
mechanism may freeze the parking brake, making it hard to release.
Keep ice and snow from accumulating under the
fenders.
Ice and snow built up under your fenders can make
steering difficult. During bad winter driving, stop and
check under the fenders occasionally.

IN CASE OF AN EMERGENCY
386
IF YOU LOSE YOUR KEYS ORLOCK YOURSELF OUT
You can purchase a new key at your Lexus dealer if
you can give them the key number and master key.
Even if you lose only one key, contact your Lexus dealer
to make a new key. If you lose all your master keys, you
cannot make new keys; the whole engine immobiliser
system must be replaced.
See the suggestion given in ªKeysº on page 9.
You can use the wireless remote control system with the
new key. Contact your Lexus dealer for detailed
information.
If your keys are locked in the vehicle and you cannot get
a duplicate, many Lexus dealers can still open the door
for you, using their special tools. If you must break a
window to get in, we suggest breaking the smallest side
window because it is the least expensive to replace. Be
extremely cautious to avoid cuts from the glass.
