TOWING TIPS
Before towing, practice turning, stopping and
backing the trailer in an area away from heavy
traffic.
If using a manual transmission vehicle for trailer
towing, all starts must be in first gear to avoid
excessive clutch slippage.
Automatic Transmission — If Equipped
Select the DRIVE range when towing. The
transmission controls include a drive strategy to
avoid frequent shifting when towing. However, if
frequent shifting does occur while in DRIVE, you
can use the AutoStick shift control to manually
select a lower gear.
NOTE:Using a lower gear while operating the vehicle
under heavy loading conditions, will improve
performance and extend transmission life by
reducing excessive shifting and heat build-up. This
action will also provide better engine braking.
AutoStick — If Equipped
When using the AutoStick shift control, select
the highest gear that allows for adequate perfor -
mance and avoids frequent downshifts. For
example, choose “5” if the desired speed can be
maintained. Choose “4” or “3” if needed to
maintain the desired speed.
To prevent excess heat generation, avoid
continuous driving at high RPM. Return to a
higher gear or vehicle speed when grade and
road conditions allow.
Cruise Control — If Equipped
Do not use in hilly terrain or with heavy loads.
When using the Cruise Control, if you experience
speed drops greater than 10 mph (16 km/h),
disengage until you can get back to cruising
speed.
Use Cruise Control in flat terrain and with light
loads to maximize fuel efficiency.

STARTING AND OPERATING213
CROSSING DITCHES, STREAMS, SHALLOW
RIVERS OR OTHER FLOWING WATER
Flowing water can be extremely dangerous. Never
attempt to cross a fast running stream or river
even in shallow water. Fast moving water can
easily push your vehicle downstream, sweeping it
out of control. Even in very shallow water, a high
current can still wash the dirt out from around your
tires putting you and your vehicle in jeopardy.
There is still a high risk of personal injury and
vehicle damage with slower water currents in
depths greater than the vehicle's running ground
clearance. You should never attempt to cross
flowing water which is deeper than the vehicle's
running ground clearance. Even the slowest
current can push the heaviest vehicle downstream
and out of control if the water is deep enough to
push on the large surface area of the vehicle's
body. Before you proceed, determine the speed of
the current, the water's depth, approach angle,
bottom condition and if there are any obstacles.
Then cross at an angle heading slightly upstream
using the low and slow technique.
After Driving Off-Road
Off-road operation puts more stress on your
vehicle than does most on-road driving. After going
off-road, it is always a good idea to check for
damage. That way you can get any problems taken
care of right away and have your vehicle ready
when you need it.
Completely inspect the underbody of your
vehicle. Check tires, body structure, steering,
suspension, driveline, and exhaust system for
damage.
Inspect the radiator for mud and debris and
clean as required.
Check threaded fasteners for looseness, partic -
ularly on the chassis, drivetrain components,
steering, and suspension. Retighten them, if
required, and torque to the values specified in
the Service Manual.
Check for accumulations of plants or brush.
These things could be a fire hazard. They might
hide damage to fuel lines, brake hoses, axle
pinion seals, and propeller shafts.
After extended operation in mud, sand, water, or
similar dirty conditions, have the radiator, fan,
brake rotors, wheels, brake linings, and axle
yokes inspected and cleaned as soon as
possible.
NOTE:Inspect the clutch vent holes in the manual trans -
mission bell housing for mud and debris and clean
as required.
If you experience unusual vibration after driving
in mud, slush or similar conditions, check the
wheels for impacted material. Impacted mate -
rial can cause a wheel imbalance and freeing
the wheels of it will correct the situation.
CAUTION!
Muddy waters can reduce the cooling system
effectiveness by depositing debris onto the
radiator.
WARNING!
Never drive through fast moving deep water. It
can push your vehicle downstream, sweeping it
out of control. This could put you and your
passengers at risk of injury or drowning.
WARNING!
Abrasive material in any part of the brakes may
cause excessive wear or unpredictable braking.
You might not have full braking power when you
need it to prevent a collision. If you have been
operating your vehicle in dirty conditions, get
your brakes checked and cleaned as necessary.

TPMS Warning Light. Driving the vehicle may cause
the tire pressure to rise to approximately 28 psi
(193 kPa), but the TPMS Warning Light will still be
on. In this situation, the TPMS Warning Light will
turn off only after the tires are inflated to the
vehicle’s recommended cold placard pressure
value.
NOTE:When filling warm tires, the tire pressure may need
to be increased up to an additional 4 psi (28 kPa)
above the recommended cold placard pressure in
order to turn the TPMS Warning Light off.
NOTE:
The TPMS is not intended to replace normal tire
care and maintenance, or to provide warning of
a tire failure or condition.
The TPMS should not be used as a tire pressure
gauge while adjusting your tire pressure, unless
your vehicle is equipped with a Tire Fill Alert
(TFA) system.
Driving on a significantly underinflated tire
causes the tire to overheat and can lead to tire
failure. Underinflation also reduces fuel effi
-
ciency and tire tread life, and may affect the
vehicle’s handling and stopping ability.
The TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsibility
to maintain correct tire pressure using an accu -
rate tire pressure gauge, even if underinflation
has not reached the level to trigger illumination
of the TPMS Warning Light.
Seasonal temperature changes will affect tire
pressure, and the TPMS will monitor the actual
tire pressure in the tire Ú page 432.
System Operation
The Tire Pressure Monitoring System (TPMS) uses
wireless technology with wheel rim mounted
electronic sensors to monitor tire pressure levels.
Sensors, mounted to each wheel as part of the
valve stem, transmit tire pressure readings to the
receiver module.

Tire Pressure Monitoring System Display

CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures
and warning have been established for the tire
size equipped on your vehicle. Undesirable
system operation or sensor damage may
result when using replacement equipment
that is not of the same size, type, and/or style.
The TPMS sensor is not designed for use on
aftermarket wheels, and may contribute to a
poor overall system performance. Customers
are encouraged to use Original Equipment
Manufacturer (OEM) wheels to ensure TPMS
feature operation.
Using aftermarket tire sealants may cause the
Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an
aftermarket tire sealant it is recommended
that you take your vehicle to an authorized
dealer to have your sensor function checked.
After inspecting or adjusting the tire pressure
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the
valve stem, which could damage the TPMS
sensor.
CAUTION!

the engine compartment and fuel tank before
resetting the system and starting the engine. If
there are no fuel leaks or damage to the vehicle
electrical devices (e.g. headlights) after an
accident, reset the system by following the
procedure described below. If you have any doubt,
contact an authorized dealer.
Enhanced Accident Response System
Reset Procedure
In order to reset the Enhanced Accident Response
System functions after an event, the ignition switch
must be changed from ignition START or ON/RUN
to ignition OFF. Carefully check the vehicle for fuel
leaks in the engine compartment and on the
ground near the engine compartment and fuel
tank before resetting the system and starting the engine. After an accident, if the vehicle will not
start after performing the reset procedure, the
vehicle must be towed to an authorized dealer to
be inspected and to have the Enhanced Accident
Response System reset.

PERIODIC SAFETY CHECKS YOU SHOULD
M
AKE OUTSIDE THE VEHICLE
Tires
Examine tires for excessive tread wear and uneven
wear patterns. Check for stones, nails, glass, or
other objects lodged in the tread or sidewall.
Inspect the tread for cuts and cracks. Inspect
sidewalls for cuts, cracks, and bulges. Check the
lug nut/bolt torque for tightness. Check the tires
(including spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check the area under vehicle after overnight
parking for fuel, coolant, oil, or other fluid leaks.
Also, if gasoline fumes are detected or if fuel or
brake fluid leaks are suspected, the cause should
be located and corrected immediately.
 ALWAYS REMOVE THE EXISTING
