Toyota Yaris: Driving Tips / Winter Driving
Carry emergency gear, including tire chains, window scraper, flares, a
small shovel, jumper cables, and 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.
- 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.
- Inspect the ignition system for damage and loose connections.
- Use washer fluid made with antifreeze-but do
not use engine coolant antifreeze for washer fluid.
- 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
frozen 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
several times until the brake performance returns to normal.
If you must rock the vehicle to free it from snow, sand or mud, depress
the accelerator slightly and slowly move the shift lever from 1 (D) to R
position...
Use snow tires on all four wheels
Do not go faster than 75 mph (120 km/h) while driving with snow
tires. Inflate snow tires 30 kPa (0.3 kgf/cm2, 4.3 psi) more than recommended on
the tire pressure label (driver’s door frame), but
never more than the maximum cold-tire pressure shown on the
tires...
