Information
An inappropriately disposed battery can be
harmful to the environment and human health.
Dispose of the battery according to your local
law(s) or regulation.

Reset Items
The following items may need to be reset
after the battery has been discharged or
the battery has been disconnected:
• Drive info/After Recharging/Accumulated info (items in
View modes) (refer to chapter 4)
• Integrated Memory System (refer to chapter 5)
• Power Windows (refer to chapter 5)
• Wide Sunroof (if equipped) (refer to chapter 5)
• Power Trunk (refer to chapter 5)
• Automatic Climate Control System (refer to chapter 5)
• Clock (refer to the Infotainment system manual)
• Infotainment System (refer to the Infotainment system manual)
Tires and Wheels
WARNING Tire failure may cause loss of vehicle
control resulting in an accident. To
reduce risk of SERIOUS INJURY or
DEATH, take the following
precautions:
• Inspect your tires monthly for proper inflation as well as wear and
damage.
• The recommended cold tire pressure for your vehicle can be
found in this manual and on the tire
label located on the driver’s side
center pillar. Always use a tire
pressure gauge to measure tire
pressure. Tires with too much or
too little pressure wear unevenly
causing poor handling.
• Check the pressure of the spare every time you check the pressure
of the other tires on your vehicle.
• Replace tires that are worn, show uneven wear, or are damaged.
Worn tires can cause loss of braking
effectiveness, steering control, or
traction.
• ALWAYS replace tires with the same size, type, construction and
tread pattern as each tire that was
originally supplied with this vehicle.
Using tires and wheels other than
the recommended sizes could
cause unusual handling
characteristics, poor vehicle
control, or negatively affect your
vehicle’s Anti-Lock Brake System
(ABS) resulting in a serious
accident.

cords that extend to the beads are
laid at 90 degrees to the centerline of
the tread.
Rim
A metal support for a tire and upon
which the tire beads are seated.Sidewall
The portion of a tire between the
tread and the bead.
Speed rating
An alphanumeric code assigned to a
tire indicating the maximum speed at

Traction
The friction between the tire and the
road surface. The amount of grip
provided.
Tread
The portion of a tire that comes into
contact with the road.
Treadwear indicators
Narrow bands, sometimes called
“wear bars”, that show across the
tread of a tire when only 1/16 in. of

UTQGS
Uniform Tire Quality Grading
Standards is a tire information system
that provides consumers with ratings
for a tire’s traction, temperature and
treadwear. Ratings are determined
by tire manufacturers using
government testing procedures. The
ratings are molded into the sidewall
of the tire.
