238SERVICING AND MAINTENANCE
Do not install a wheel cover or attempt to mount a
conventional tire on the compact spare wheel,
since the wheel is designed specifically for the
compact spare tire. Do not install more than one
compact spare tire and wheel on the vehicle at any
given time.
Collapsible Spare Tire — If Equipped
The collapsible spare is for temporary emergency
use only. You can identify if your vehicle is
equipped with a collapsible spare by looking at the
spare tire description on the Tire and Loading
Information Placard located on the driver’s side
door opening or on the sidewall of the tire.
Collapsible spare tire description example:
165/80-17 101P.

Since this tire has limited tread life, the original
equipment tire should be repaired (or replaced) and
reinstalled on your vehicle at the first opportunity.
Inflate collapsible tire only after the wheel is
properly installed to the vehicle. Inflate the
collapsible tire using the electric air pump before
lowering the vehicle.
Do not install a wheel cover or attempt to mount a
conventional tire on the collapsible spare wheel,
since the wheel is designed specifically for the
collapsible spare tire.Full Size Spare — If Equipped

The full size spare is for temporary emergency use only.
This tire may look like the originally equipped tire on the
front or rear axle of your vehicle, but it is not. This spare
tire may have limited tread life. When the tread is worn
to the tread wear indicators, the temporary use full size
spare tire needs to be replaced. Since it is not the same
as your original equipment tire, replace (or repair) the
original equipment tire and reinstall on the vehicle at
the first opportunity.

NOTE:This spare tire may not have a TPMS sensor.
Limited Use Spare — If Equipped
The limited use spare tire is for temporary
emergency use only. This tire is identified by a
label located on the limited use spare wheel.
This label contains the driving limitations for this
spare. This tire may look like the original equipped
tire on the front or rear axle of your vehicle, but it is
not. Installation of this limited use spare tire
affects vehicle handling. Since it is not the same as
your original equipment tire, replace (or repair) the
original equipment tire and reinstall on the vehicle
at the first opportunity.
WARNING!

Compact and collapsible spares are for temporary
emergency use only. With these spares, do not drive
more than 50 mph (80 km/h). Temporary use spares
have limited tread life. When the tread is worn to the
tread wear indicators, the temporary use spare tire
needs to be replaced. Be sure to follow the warnings,
which apply to your spare. Failure to do so could
result in spare tire failure and loss of vehicle control.

240SERVICING AND MAINTENANCE
SNOW TRACTION DEVICES
Use of traction devices require sufficient tire-to-body clearance. Due to limited clearance the following traction devices are recommended. Follow these
recommendations to guard against damage.
Snow traction device must be of proper size for the tire, as recommended by the traction device manufacturer.
No other tire sizes are recommended for use with a tire chain or traction device.
Please see the following table for the recommended tire size, axle and snow traction device:
FWD
Trim Level Axle Tire/Wheel Size Snow Traction Device (maximum projection beyond tire profile or equivalent)
All
FrontLT225/75R16E
225/75R16C Quality Chain Corp Light Truck Highway Service (Non-Cam) tire chain or equivalent is
recommended.
WARNING!
Using tires of different size and type (M+S, Snow) between front and rear axles can cause unpredictable handling. You could lose control and have a collision.

TECHNICAL SPECIFICATIONS
VEHICLE IDENTIFICATION NUMBER (VIN)
The VIN is found on the left front corner of the
instrument panel, visible through the windshield.
Vehicle Identification Number

NOTE:It is illegal to remove or alter the VIN.
BRAKE SYSTEM
Your vehicle is equipped with dual hydraulic brake
systems. If either of the two hydraulic systems lose
normal capability, the remaining system will still
function. However, there will be some loss of
overall braking effectiveness. You may notice
increased pedal travel during application, greater
pedal force required to slow or stop, and potential
activation of the Brake System Warning Light.
In the event power assist is lost for any reason (i.e.,
repeated brake applications with the engine off),
the brakes will still function. However, the effort
required to brake the vehicle will be much greater
than that required with the power system
operating.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to
ensure that the wheel is properly mounted to the
vehicle. Any time a wheel has been removed and
reinstalled on the vehicle, the lug nuts/bolts
should be torqued using a properly calibrated
torque wrench using a six-sided (hex) deep wall
socket.
TORQUE SPECIFICATIONS
**Use only authorized dealer recommended lug
nuts/bolts and clean or remove any dirt or oil
before tightening.
