Winter driving tips
Carry out the necessary preparations and inspections before driving the
vehicle in winter. Always drive the vehicle in a manner appropriate to the
prevailing weather conditions. 
■ Pre-winter preparations
●Use fluids that are appropria te to the prevailing outside tempera-
tures. 
• Engine oil
• Engine coolant
• Washer fluid
● Have a service technician inspect  the level and specific gravity of
battery electrolyte.
● Have the vehicle fitted with four  snow tires or purchase a set of
tire chains for the rear tires. 
Ensure that all tires are the specified size and the same brand, and that
chains match the size of the tires.
■ Before driving the vehicle
Perform the following according  to the driving conditions. 
● Do not try to forcibly open a window or move a wiper that is fro-
zen. Pour warm water over the frozen area to melt the ice. Wipe
away the water immediately to prevent it from freezing. 
● To ensure proper operation of the climate control system fan,
remove any snow that has accumu lated on the air inlet vents in
front of the windshield. 
● Remove any ice that has accumul ated on the vehicle chassis. 
● Periodically check for and remove any excess ice or snow that
may have accumulated in the wheel well or on the brakes.

Vehicle specifications
■DOT quality grades
All passenger vehicle tires must co nform to Federal Safety Require-
ments in addition to these grades.  Quality grades can be found where
applicable on the tire sidewall  between tread shoulder and maximum
section width.
For example: Treadwear 200 Traction AA Temperature A
■ Treadwear
The treadwear grade is a comparative  rating based on the wear rate of
the tire when tested under controll ed conditions on a specified gov-
ernment test course.
For example, a tire graded 150 would wear one and a half (1 - 1 /2) times as
well on the government course as a tire graded 100.
The relative performance of tires de pends upon the actual conditions of
their use, however, and may depart significantly from the norm due to varia-
tions in driving habits, service practices and differences in road characteris-
tics and climate.
■ Traction AA, A, B, C
The traction grades, from highest to  lowest, are AA, A, B and C, and
they represent the tire's ability to  stop on wet pavement as measured
under controlled condit ions on specified government test surfaces of
asphalt and concrete.
A tire marked C may have poor traction performance.
Warning: The traction grade assigned  to this tire is based on braking
(straight ahead) traction tests and does  not include cornering (turning) trac-
tion.
