2-8. Driving Tips
Winter Driving
Carry emergency gear, including tire chains, window scraper, flares, a
small shovel, jumper cables, a nd a small bag of sand or salt.
Ask your Toyota dealer to check the following: • Have the proper ratio of antifreeze in the radiator. Refer to Engine Coolant on P. 425.
• Inspect the battery and its cables . Cold reduces battery capacity.
• Use an engine oil appropriate for the lowest ambient temperatures that the vehicle will be driven in ( →P. 422).
• Inspect the ignition sy stem for damage and loose connections.
• Use washer fluid made with antifreeze ⎯but do not use engine cool-
ant antifreeze for washer fluid ( →P. 429).
●Do not use the parking brake in freezing weather as it may freeze. Instead,
shift to 1 or R with a manual transaxle and to P with an automatic transaxle.
Block the rear wheels.
● Remove snow before driving. Snow left on the windshield is dangerous as it
could obstruct vision.
● Do not apply excessive force to a window scraper when removing ice or fro-
zen snow on the mirror glass and windshield.
● Never use warm or hot water for removing snow or ice from windows and
mirrors as it could result in the glass cracking.
● Drive slowly. Braking performance can be adversely affected if snow or ice
adheres to the brake components. If this situation occurs, drive the vehicle
slowly, releasing the accelerator pedal and lightly applying the brakes sev-
eral times until the brake performance returns to normal.

When Driving
When the ignition is switched ON,
the wrench indicator light is illumi-
nated and then turns off after a
few seconds.
The wrench indicator light is illu-
minated when the preset mainte-
nance period arrives. Verify the
content and perform mainte-
nance.
Refer to Maintenance Monitor on
P. 414.
The light illuminates continuously
when the engine coolant tempera-
ture is low and turns off after the
engine is warm.
If the low engine coolant tempera-
ture indicator light remains illumi-
nated after the engine has been
sufficiently warmed up, the tem-
perature sensor could have a mal-
function. Consult your Toyota
dealer.

extreme cold position and set the air intake selector to the recirculated air
position, then set the fan control dial to position 4.
● If warmer air is desired at floor level, set the mode selector dial to the
position and adjust the temperature control dial to maintain maximum com-
fort.
● The air to the floor is warmer than air to the face (except when the tempera-
ture control dial is set at the extreme hot or cold position).

Maintenance and Care
Engine Coolant
Inspect the antifreeze protection and coolant level in the coolant res-
ervoir at least once a year—at t he beginning of the winter season—
and before traveling where temperatures may drop below freezing.
Inspect the condition and connecti ons of all cooling system and
heater hoses.
Replace any that are swollen or deteriorated.
The coolant should be at full in the
radiator and between the F and L
marks on the coolant reservoir
when the engine is cool.
Cooling fan
Cooling system cap
Coolant reservoir
If it is at or near L, add enough coolant to the coolant reservoir to pro-
vide freezing and corrosion protecti on and to bring the level to F.
Securely tighten the coolant reserv oir tank cap after adding coolant.
If the coolant reservoir is empty or new coolant is required frequently,
consult your Toyota dealer.
Changing the coolant should be done by your Toyota dealer.
