Tire Types
All Season Tires — If Equipped
All Season tires provide traction for all seasons (Spring,
Summer, Fall, and Winter). Traction levels may vary
between different all season tires. All season tires can be
identified by the M+S, M&S, M/S or MS designation on the
tire sidewall. Use all season tires only in sets of four; failure
to do so may adversely affect the safety and handling of your
vehicle.Summer Or Three Season Tires — If Equipped
Summer tires provide traction in both wet and dry condi
-
tions, and are not intended to be driven in snow or on ice. If
your vehicle is equipped with Summer tires, be aware these
tires are not designed for Winter or cold driving conditions.
Install Winter tires on your vehicle when ambient tempera -
tures are less than 40°F (5°C) or if roads are covered with ice
or snow. For more information, contact an authorized dealer.
Summer tires do not contain the all season designation or
mountain/snowflake symbol on the tire sidewall. Use
Summer tires only in sets of four; failure to do so may
adversely affect the safety and handling of your vehicle.
• Never use a tire with a smaller load index or capacity,
other than what was originally equipped on your
vehicle. Using a tire with a smaller load index could
result in tire overloading and failure. You could lose
control and have a collision.
• Failure to equip your vehicle with tires having adequate speed capability can result in sudden tire
failure and loss of vehicle control.
CAUTION!
Replacing original tires with tires of a different size may
result in false speedometer and odometer readings.
WARNING! (Continued)
WARNING!
Do not use Summer tires in snow/ice conditions. You
could lose vehicle control, resulting in severe injury or
death. Driving too fast for conditions also creates the
possibility of loss of vehicle control.

SERVICING AND MAINTENANCE 461
Snow Tires
Some areas of the country require the use of snow tires
during the Winter. Snow tires can be identified by a “moun-
tain/snowflake” symbol on the tire sidewall.
If you need snow tires, select tires equivalent in size
and type to the original equipment tires. Use snow
tires only in sets of four; failure to do so may
adversely affect the safety and handling of your vehicle.
Snow tires generally have lower speed ratings than what was
originally equipped with your vehicle and should not be
operated at sustained speeds over 75 mph (120 km/h). For speeds above 75 mph (120 km/h) refer to original equipment
or an authorized tire dealer for recommended safe operating
speeds, loading and cold tire inflation pressures.
While studded tires improve performance on ice, skid and
traction capability on wet or dry surfaces may be poorer than
that of non-studded tires. Some states prohibit studded tires;
therefore, local laws should be checked before using these
tire types.Spare Tires — If Equipped
NOTE:
For vehicles equipped with Tire Service Kit instead of a spare
tire, please refer to “Tire Service Kit” in “In Case Of Emer -
gency” for further information.
Refer to the “Towing Requirements - Tires” in “Starting And
Operating” for restrictions when towing with a spare tire
designated for temporary emergency use.
Spare Tire Matching Original Equipped Tire And Wheel
— If Equipped
Your vehicle may be equipped with a spare tire and wheel
equivalent in look and function to the original equipment
tire and wheel found on the front or rear axle of your vehicle.
This spare tire may be used in the tire rotation for your
vehicle. If your vehicle has this option, refer to an authorized
tire dealer for the recommended tire rotation pattern.
CAUTION!
Because of the reduced ground clearance, do not take
your vehicle through an automatic car wash with a
compact or limited use temporary spare installed.
Damage to the vehicle may result.

SERVICING AND MAINTENANCE 467
Refer to the “Maintenance Plan” for the proper maintenance
intervals. More frequent rotation is permissible if desired.
The reasons for any rapid or unusual wear should be
corrected prior to rotation being performed.Tire Rotation
NOTE:
On Canadian vehicles only, if your vehicle is equipped with
All-Season type tires on the front and On/Off Road type tires
mounted on the rear, do not use a front to back rotation
pattern. Instead, rotate your tires side to side at the recom -
mended intervals. Dual Rear Wheels
Tire Rotation
The tires used on dual wheel assemblies should be matched
for wear to prevent overloading one tire in a set. To check if
tires are even, lay a straight edge across all four tires. The
straight edge should touch all the tires.

Media Mode
Pushing the top of the switch once will go to the next track
on the selected media (AUX/USB/Bluetooth/CD). Pushing
the bottom of the switch once goes to the beginning of the
current track, or to the beginning of the previous track if it is
within eight seconds after the current track begins to play.
IPOD/USB/MP3 CONTROL — IF EQUIPPED
Located on the center stack, just below the instrument panel,
is the main media hub. There are four total USB Ports : Two
Mini-USBs (Type C) and two Standard USBs (Type A). There
is also an AUX Port located in the middle of the USB Ports.
All four of the USB Ports include a USB Trident and a numer-
ical value one through three, which indicates that the vehicle
can support three fully-functioning USB Ports at a time. Each
USB Port will support media and charging simultaneously.
NOTE:
• The Type C USB port is the primary media port for the radio. Two devices can be plugged in at the same time and
both ports provide charging capabilities, but only one port
can transfer data to the head unit at a time.
• Both ports share a single data connection. However, the user cannot switch between Type A or Type C. For example, if a device is plugged into the Type A USB port
and another device is plugged into the Type C port, connec
-
tion to the Type A port will be lost. Alternatively, if a device
is plugged into the Type C port and another device is
plugged into the Type A port, the Type C device maintains
primary connection.
