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 follow the table below for the recommended tire size, axle and snow traction device:

All Front LT225/75R16E
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.8

TECHNICAL SPECIFICATIONS
VEHICLE IDENTIFICATION NUMBER
The Vehicle Identification Number (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 loses 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.
