Check the condition of the 12 volt bat-
tery and cables.
Cold temperatures reduce the capacity of
any 12 volt battery, so it must be in top
shape to provide enough power for winter
starting. Section 8−3 tells you how to
visually inspect the 12 volt battery. Your
Toyota dealer will be pleased to check the
level of charge.
Make sure the engine oil viscosity is
suitable for the cold weather.
See page 405 for recommended viscosity.
Leaving a heavy summer oil in your ve-
hicle during winter months may cause
harder starting. If you are not sure about
which oil to use, call your Toyota deal-
er—they will be pleased to help.
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 anti
freeze solution.
This product is available at your Toyota
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 dam-
age your vehicle’s paint.
Do not use your parking brake when
there is a possibility it could freeze.
When parking, push the “P” position
switch and block the rear wheels. Do not
use the parking brake, for snow or water
accumulated in and around the parking
brake mechanism may freeze, 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 extreme
winter driving, stop and check under the
fenders occasionally.
Depending on where you are driving,
we recommend you carry some emer-
gency equipment.
Some of the things you might put in the
vehicle are tire chains, window scraper,
bag of sand or salt, flares, small shovel,
jumper cables, etc.40p050b
Your vehicle is not designed to be
dinghy towed (with four wheels on the
ground) behind a motorhome.
NOTICE
Do not tow your vehicle with four
wheels on the ground. This may cause
serious damage to your vehicle.
Dinghy towing

CAUTION
Never turn off the hybrid system to
coast down hills. Your power steering
and brake booster will not function
without the hybrid system running.
Also, the emission control system op-
erates properly only when the hybrid
system is running.

364
If your hybrid system stalls while driving...1. Reduce your speed gradually, keeping a straight line. Move cautiously off the
road to a safe place.
2. Turn on your emergency flashers.
3. Try starting the hybrid system again.
If the hybrid system will not start, see “If
your vehicle will not start” on page 360.
CAUTION
If the hybrid system is not operating,
the power assist for the brakes and
steering will not work so steering and
braking will be much harder than usu-
al.
If your high coolant temperature warn-
ing light comes on, if you experience a
loss of power, or if you hear a loud
knocking or pinging noise, the hybrid
system has probably overheated. You
should follow this procedure...
1. Pull safely off the road, stop the ve- hicle and turn on your emergency
flashers. Push the “P” position switch
and apply the parking brake. Turn off
the air conditioning if it is being used.
2. If coolant or steam is boiling out of the radiator or reservoir, stop the hybrid
system. Wait until the steam subsides
before opening the hood. If there is no
coolant boiling over or steam, leave the
hybrid system running and make sure
the electric cooling fan is operating. If
it is not, turn the hybrid system off.
CAUTION
To help avoid personal injury, keep
the hood closed until there is no
steam. Escaping steam or coolant is
a sign of very high pressure.
3. Look for obvious coolant leaks from theradiator, hoses, and under the vehicle.
However, note that water draining from
the air conditioning is normal if it has
been used.
CAUTION
When the hybrid system is running,
keep hands and clothing away from
the moving fan and engine drive
belts.
4. If the coolant is leaking, stop the hy-brid system immediately. Call a Toyota
dealer for assistance.
5. If there are no obvious leaks, check the coolant reservoir. If it is dry, add
coolant to the reservoir while the hy-
brid system is running. Fill it about half
full.
CAUTION
Do not attempt to remove the radiator
cap when the hybrid system and ra-
diator are hot. Serious injury could
result from scalding hot fluid and
steam blown out under pressure.

CAUTION
Use extreme caution when towing ve-
hicles. Avoid sudden starts or erratic
driving maneuvers which would place
excessive stress on the emergency
towing eyelet and towing cable or
chain. The eyelet and towing cable or
chain may break and cause serious
injury or damage.
NOTICE
Use only a cable or chain specifically
intended for use in towing vehicles.
Securely fasten the cable or chain to
the towing eyelet provided.
Before towing, release the parking brake
and put the hybrid transaxle in “N”. The
hybrid system must be in the “IG−ON”
mode.
In the following cases, as the front wheels
might be locked by means of the parking
lock mechanism, your vehicle cannot be
towed by another vehicle using a rope.
Have your vehicle carried with the front
wheels or all the wheels raised.
If the parking mechanism fails.
If the 12 volt battery is discharged.
CAUTION
If the hybrid system is not running,
the power assist for the brakes and
steering will not work so steering and
braking will be much harder than usu-
al.
