184SERVICING AND MAINTENANCE  
(Continued)
NOTE:
If you intend parking or storing your vehicle for 
an extended period after cleaning the wheels 
with wheel cleaner, drive your vehicle and apply 
the brakes to remove the water droplets from 
the brake components. This activity will remove 
the red rust on the brake rotors and prevent 
vehicle vibration when braking. Dark Vapor Chrome, Black Satin Chrome, or 
Low Gloss Clear Coat Wheels
Tire Chains And Traction Devices 
Use of traction devices require sufficient 
tire-to-body clearance. Due to limited clearance 
the following traction devices are recom
-
mended. Follow these recommendations to 
guard against damage.
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.
Install on front tires only.
For LT225/75R16 and 215/75R16C tires 
use of a Quality Chain Corp Light Truck 
Highway Service (Non-Cam) tire chain or 
equivalent snow traction device is recom -
mended.
CAUTION!
Do not use scouring pads, steel wool, a bristle 
brush, metal polishes or oven cleaner. These 
products may damage the wheel's protective 
finish. Such damage is not covered by the 
New Vehicle Limited Warranty. Only car wash 
soap, Mopar Wheel Cleaner or equivalent is 
recommended.CAUTION!
If your vehicle is equipped with these 
specialty wheels, DO NOT USE wheel 
cleaners, abrasives, or polishing compounds. 
They will permanently damage this finish and 
such damage is not covered by the New 
Vehicle Limited Warranty. HAND WASH ONLY 
USING MILD SOAP AND WATER WITH A SOFT 
CLOTH. Used on a regular basis; this is all that 
is required to maintain this finish.
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.
CAUTION!
To avoid damage to your vehicle or tires, 
observe the following precautions:
Because of restricted traction device clear -
ance between tires and other suspension 
components, it is important that only trac-
tion devices in good condition are used. 
Broken devices can cause serious damage. 
Stop the vehicle immediately if noise 
occurs that could indicate device breakage. 
Remove the damaged parts of the device 
before further use.

TECHNICAL SPECIFICATIONS
IDENTIFICATION DATA
Vehicle Identification Number 
The Vehicle Identification Number (VIN) is found 
on the left front corner of the instrument panel, 
visible through the windshield. This number 
also appears on the vehicle frame and under-
body as well as the Automobile Information 
Disclosure Label affixed to a window on your 
vehicle, the vehicle registration and title.
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 appli
-
cation, 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 cali -
brated torque wrench using a high quality 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.
