Towing Tips
Before setting out on a trip, practice turning, stopping, and
backing up the trailer in an area located away from heavy
traffic.
Automatic Transmission
The DRIVE range can be selected when towing. The
transmission controls include a drive strategy to avoid
frequent shifting when towing. However, if frequent shift-
ing does occur while in DRIVE, use the Electronic Range
Select (ERS) shift control to select a lower gear range.
NOTE:Using a lower gear range while operating the
vehicle under heavy loading conditions will improve per-
formance and extend transmission life by reducing exces-
sive shifting and heat build up. This action will also
provide better engine braking.
Electronic Speed Control — If Equipped
• Do not use in hilly terrain or with heavy loads.
• When using the speed control, if you experience speed
drops greater than 10 mph (16 km/h), disengage until
you can get back to cruising speed.
• Use speed control in flat terrain and with light loads to
maximize fuel efficiency.

STARTING AND OPERATING 377

Driving In Snow, Mud And Sand
In heavy snow, when pulling a load, or for additional
control at slower speeds, shift the transmission to a low
gear and shift the 4WD system to the appropriate terrain
mode, using 4WD LOW if necessary. Refer to “Four-Wheel
Drive Operation” in “Starting And Operating” for further
information. Do not shift to a lower gear than necessary to
maintain headway. Over-revving the engine can spin the
wheels and traction will be lost.
Avoid abrupt downshifts on icy or slippery roads because
engine braking may cause skidding and loss of control.
Hill Climbing
NOTE:Before attempting to climb a hill, determine the
conditions at the crest and/or on the other side.
Before climbing a steep hill, shift the transmission to a
lower gear and shift the 4WD System to 4WD LOW. Use
first gear and 4WD LOW for very steep hills.
NOTE: Brakes should be applied at increased slippage, but
before coming to a stop to avoid digging into the loose
surface and rendering the operator of the vehicle stuck/
immobile. If you stall or begin to lose headway
while climbing a
steep hill, allow your vehicle to come to a stop and
immediately apply the brakes. Once stopped, shift to
REVERSE. Back slowly down the hill allowing the com-
pression braking of the engine to help regulate your speed.
If the brakes are required to control vehicle speed, apply
them lightly and avoid locking or skidding the tires.
WARNING!
If the engine stalls or you lose headway or cannot
make it to the top of a steep hill or grade, never attempt
to turn around. To do so may result in tipping and
rolling the vehicle. Always back straight down a hill in
REVERSE gear carefully. Never back down a hill in
NEUTRAL using only the brake.
NOTE: Remember, never drive diagonally across a hill -
drive straight up or down.
If the wheels start to slip as you approach the crest of a hill,
ease off the accelerator and maintain headway by turning
the front wheels slowly left and right. This may provide a
fresh “bite” into the surface and may provide traction to
complete the climb.6
STARTING AND OPERATING 387

•Maintain engine coolant (antifreeze) concentration at a
minimum of 50% OAT coolant (conforming to
MS.90032) and distilled water for proper corrosion pro-
tection of your engine which contains aluminum com-
ponents.
• Make sure that the coolant expansion bottle overflow
hoses are not kinked or obstructed.
• Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean.
• Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install ONLY
the correct type thermostat. Other designs may result in
unsatisfactory engine coolant (antifreeze) performance,
poor gas mileage, and increased emissions.
Brake System
In order to assure brake system performance, all brake
system components should be inspected periodically. Refer
to the “Maintenance Plan” in this section for the proper
maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure and possi-
bly a collision. Driving with your foot resting or riding
on the brake pedal can result in abnormally high brake
temperatures, excessive lining wear, and possible
brake damage. You would not have your full braking
capacity in an emergency.
Fluid Level Check — Brake Master Cylinder
The fluid level of the master cylinder should be checked
whenever the vehicle is serviced, or immediately if the
brake system warning light is on. If necessary, add fluid to
bring level to the full mark on the side of the reservoir of
the brake master cylinder. Be sure to clean the top of the
master cylinder area before removing cap. With disc
brakes, fluid level can be expected to fall as the brake pads
wear. Brake fluid level should be checked when pads are
replaced. If the brake fluid is abnormally low, check system
for leaks.
Refer to “Fluids And Lubricants” in “Technical Specifica-
tions” for further information.
478 SERVICING AND MAINTENANCE

CAUTION!
Avoid products or automatic car washes that use acidic
solutions or strong alkaline additives or harsh brushes.
These products and automatic car washes 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.
When cleaning extremely dirty wheels including excessive
brake dust, care must be taken in the selection of tire and
wheel cleaning chemicals and equipment to prevent dam-
age to the wheels. Mopar Wheel Treatment or Mopar
Chrome Cleaner or their equivalent is recommended or
select a non-abrasive, non-acidic cleaner for aluminum or
chrome wheels. Do not use any products on Dark Vapor or
Black Satin Chrome Wheels. They will permanently dam-
age this finish and such damage is not covered by the New
Vehicle Limited Warranty.
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 equiva-
lent is recommended.
NOTE: If you intend parking or storing your vehicle for an
extended period after cleaning the wheels with wheel
cleaner, drive your vehicle for a few minutes before doing
so. Driving the vehicle and applying the brakes when
stopping will reduce the risk of brake rotor corrosion.
Dark Vapor Or Black Satin Chrome Wheels
CAUTION!
If your vehicle is equipped with Dark Vapor or Black
Satin Chrome wheels DO NOT USE wheel cleaners,
abrasives or polishing compounds. They will perma-
nently damage this finish and such damage is not covered
by the New Vehicle Limited Warranty. USE ONLY MILD
SOAP AND WATER WITH A SOFT CLOTH. Used on a
regular basis this is all that is required to maintain this
finish.

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.

**Use only your authorized dealer recommended lug nuts/
bolts and clean or remove any dirt or oil before tightening. Inspect the wheel mounting surface prior to mounting the
tire and remove any corrosion or loose particles.
Tighten the lug nuts/bolts in a star pattern until each

Forward Collision Warn-
ing (FCW) Active Braking — If Equipped Far
Med Near
NOTE:
The FCW system includes Advanced Brake Assist (ABA). When this feature is selected, it will apply the brakes to
slow your vehicle in case of potential forward collision. The ABA applies additional brake pressure when the driver
requests insufficient brake pressure to avoid a potential frontal collision. The ABA system becomes active at 5 mph
(8 km/h). LaneSense Warning — If Equipped Early
Medium Late
NOTE:
When the “LaneSense Warning“ feature is selected, it sets the distance at which the steering wheel will provide feed-
back for potential lane departures. The LDW sensitivity can be set to provide either an “early,” “medium,” or “late”
warning zone start point. LaneSense Strength — If Equipped Low
Medium High
NOTE:
When the “LaneSense Strength” feature is selected, it sets the strength of the steering wheel feedback for potential
lane departures.
