Keep your foot firmly on the brake pedal when
starting the engine.
The engine is harder to start in cold weather and in
thinner air found at altitu des above 8,000 feet (2,400
meters).
When starting the engine in cold weather, turn off all
electrical accessories such as the lights, climate
control system, and rear defogger in order to reduce
battery drain.
If the exhaust system sounds abnormal or you can
smell exhaust gas inside the vehicle, have your vehicle
checked by a dealer. There may be a problem with
the engine or exhaust system.
Insert the keyless access remo te into the slot if the
battery in the key is weak. 2 If the Keyless Access Remote Battery is

Automatic Transmission
The following conditions caus e the engine to run at high revolutions, and increase
creeping:
• Immediately after the engine starts.
• When the climate control system is in use.
Keep the brake pedal firmly depressed when stopped.
Quickly depressing the accelerator pe dal while driving uphill may cause the
transmission to drop to a lower gear, unexpectedly increasing vehicle speed. Depress
the accelerator pedal carefully, especi ally on slippery roads and curves.

Maintenance
DOT Tire Quality Grading (U.S. Vehicles)
The tires on your vehicle meet all U.S. Federal Safety
Requirements. All tires are also graded for treadwear, traction,
and temperature performance according to Department of
Transportation (DOT) standards. The following explains these
gradings.
Quality grades can be found where applicable on the tire sidewall
between tread shoulder and maximum section width.
The treadwear grade is a comparative rating based on the wear
rate of the tire when tested under controlled conditions on a
specified government test course. For example, a tire graded 150
would wear one and one-half (1 1/2) times as well on the
government course as a tire graded 100. The relative performance
of tires depends upon the actual conditions of their use, however,
and may depart significantly from the norm due to variations in
driving habits, service practi ces and differences in road
characteristics and climate.

All passenger car tires must conform
to Federal Safety Requirements in
addition to these grades.

Maintenance
Climate Control System Maintenance
Dust and Pollen Filter
The climate control system is equipped with a dust and pollen filter that collects
pollen, dust, and other debris in the air. The Maintenance MinderTM messages will let
you know when to replace the filter.
We recommend that you replace the dust a nd pollen filter sooner when using your
vehicle in areas with high concentrations of dust.
1 Dust and Pollen Filter
Using an air freshener may reduce the deodorizing
effect of the dust and pollen filter, and may reduce its
life.
If the airflow from the heating and cooling system
deteriorates noticeably, and the windows fog up
easily, the filter may need to be replaced. Please
contact a dealer for replacement.
