We recommend towing a four-wheel drive
vehicle with all wheels off the ground, such
as using a wheel lift and dollies or flatbed
equipment. However, it is acceptable to
use a wheel lift to raise the rear of your
vehicle so long as, depending on vehicle
configuration, you perform the following
before towing:
•
If your vehicle has an electronic
shift-on-the-fly transfer case, make
sure you switch the four-wheel drive
control to the 2H position before
towing.
Note: Towing an electronic shift-on-the-fly
four-wheel drive vehicle with the front
wheels on the ground without disengaging
the front hubs may cause damage to the
automatic transmission.
Note: Towing a two-wheel drive vehicle or
an electronic shift-on-the-fly four-wheel
drive vehicle with the rear wheels on the
ground for more than
50 mi (80 km) or
faster than 35 mph (56 km/h) may cause
damage to the automatic transmission.
TOWING POINTS WARNING:
Using recovery hooks
is dangerous and should only be done by
a person familiar with proper vehicle
recovery safety practices. Improper use
of recovery hooks may cause hook failure
or separation from the vehicle and could
result in serious injury or death. WARNING: Always slowly remove
the slack from the recovery strap prior
to pulling. Failure to do so can introduce
significantly higher loads which can
cause the recovery hooks to break off, or
the recovery strap to fail which can cause
serious injury or death. WARNING:
Never link two straps
together with a clevis pin. These heavy
metal objects could become projectiles
if the strap breaks and can cause serious
injury or death.
Your vehicle comes equipped with
frame-mounted front recovery hooks.
These hooks should never have a load
applied to them greater than the gross
vehicle weight rating of your vehicle.
Before using recovery hooks:
• Make sure all attaching points are
secure and capable of withstanding
the applied load.
• Never use chains, cables or tow straps
with metal hook ends.
• Only use recovery straps that have a
minimum breaking strength two to
three times the gross vehicle weight of
the stuck vehicle.
• Make sure the recovery strap is in good
condition and free of visible cuts, tears
or damage.
• Use a damper device such as a tarp,
heavy blanket or piece of carpet
draped over the recovery strap to help
absorb the energy in the event the
strap breaks.
• Make sure the stuck vehicle is not
loaded heavier than its gross vehicle
weight rating specified on the
certification label.
• Always align the tow vehicle and stuck
vehicle in a straight line (within 10
degrees).
• Keep bystanders to the
sides of the
vehicle, at a distance of at least twice
the length of the recovery strap. This
helps avoid injury from the hazard of a
recovery hook or strap breaking, or a
vehicle lurching into their path.

The fuse panel is in the right-hand side of
the passenger footwell behind a trim panel.
To remove the trim panel, pull it toward
you and swing it away from the side. To
reinstall it, line up the tabs with the grooves
on the panel, and then push it shut. To remove the fuse panel cover, press in
the tabs on both sides of the cover, and
then pull it off.
To reinstall the fuse panel cover, place the
top part of the cover on the fuse panel and
push the bottom part until it latches.
Gently pull on the cover to make sure it has
latched properly. Protected Component

Recycled Coolant
We do not recommend the use of recycled
coolant as an approved recycling process
is not yet available.
Note:
Dispose of used coolant in the
appropriate manner.
Follow your community's regulations and
standards for recycling and disposing of
automotive fluids.
Severe Climates
If you drive in extremely cold climates:
• It may be necessary to increase the
coolant concentration above 50%.
• A coolant concentration of 60%
provides improved freeze point
protection. Coolant concentrations
above 60% decrease the overheat
protection characteristics of the
coolant and may cause engine
damage.
If you drive in extremely hot climates:
• You can decrease the coolant
concentration to 40%.
• Coolant concentrations below 40%
decrease the freeze and corrosion
protection characteristics of the
coolant and may cause engine
damage.
Vehicles driven year-round in non-extreme
climates should use prediluted coolant for
optimum cooling system and engine
protection.
Coolant Change
At specific mileage intervals, as listed in
the scheduled maintenance information,
the coolant should be changed. Add
prediluted coolant approved to the correct
specification. See Capacities and
Specifications (page 419). Engine-driven Cooling Fan
Your vehicle may have an engine driven
cooling fan drive also called a fan clutch.
This fan drive changes the fan speed to
match the vehicle
’s changing cooling air
flow requirements. Fan speed, fan noise
level and fuel consumption all will increase
based on the driving conditions that
include trailer towing, hill climbing, heavy
loads, high speed and high ambient
temperature, individually or in combination.
The fan drive provides the minimum fan
speed resulting in minimum fan noise and
fuel consumption required to meet the
ever-changing vehicle cooling air flow
requirements. You can hear the amount of
fan noise increasing and decreasing as the
engine power requirements and vehicle
driving conditions change as you drive. This
is normal to the operation of your vehicle.
You may also hear high levels of fan noise
when the engine first starts, and normally
decreases after driving for a short time.
Fail-Safe Cooling
Fail-safe cooling allows you to temporarily
drive your vehicle before any incremental
component damage occurs. The fail-safe
distance depends on ambient
temperature, vehicle load and terrain.
How Fail-Safe Cooling Works If the engine begins to overheat,
the coolant temperature gauge
moves toward the red zone:
A warning lamp illuminates and
a message may appear in the
information display.
If the engine reaches a preset
over-temperature condition, the engine
automatically switches to alternating
cylinder operation. Each disabled cylinder
acts as an air pump and cools the engine.

When this occurs, your vehicle still
operates, however:
•
Engine power is limited.
• The air conditioning system turns off.
Continued operation increases the engine
temperature, causing the engine to
completely shut down. Your steering and
braking effort increases in this situation.
When the engine temperature cools, you
can re-start the engine. Have your vehicle
checked as soon as possible to minimize
engine damage.
When Fail-Safe Mode Is Activated WARNING: Fail-safe mode is for
use during emergencies only. Operate
your vehicle in fail-safe mode only as
long as necessary to bring your vehicle
to rest in a safe location and seek
immediate repairs. When in fail-safe
mode, your vehicle will have limited
power, will not be able to maintain
high-speed operation, and may
completely shut down without warning,
potentially losing engine power, power
steering assist, and power brake assist,
which may increase the possibility of a
crash resulting in serious injury. WARNING:
Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap
with a thick cloth to prevent the
possibility of scalding and slowly remove
the cap. Failure to follow this instruction
could result in personal injury.
Your vehicle has limited engine power
when in the fail-safe mode, drive your
vehicle with caution. Your vehicle does not
maintain high-speed operation and the
engine may operate poorly. Remember that the engine is capable of
automatically shutting down to prevent
engine damage. In this situation:
1. Pull off the road as soon as safely
possible and switch the engine off.
2. If you are a member of a roadside assistance program, we recommend
that you contact your roadside
assistance service provider.
3. If this is not possible, wait for a short period of time for the engine to cool.
4. Check the coolant level. If the coolant level is at or below the minimum mark,
add prediluted coolant immediately.
5. When the engine temperature cools, you can re-start the engine. Have your
vehicle checked as soon as possible to
minimize engine damage.
Note: Driving your vehicle without repair
increases the chance of engine damage.
Engine Coolant Temperature
Management
(If Equipped) WARNING:
To reduce the risk of
crash and injury, be prepared that the
vehicle speed may reduce and the
vehicle may not be able to accelerate
with full power until the coolant
temperature reduces.
If you tow a trailer with your vehicle, the
engine may temporarily reach a higher
temperature during severe operating
conditions, for example ascending a long
or steep grade in high ambient
temperatures.
At this time, you may notice the coolant
temperature gauge moves toward the red
zone and a message may appear in the
information display.
