WARNING: Do not become
overconfident in the ability of four-wheel
drive vehicles. Although a four-wheel drive
vehicle may accelerate better than a
two-wheel drive vehicle in low traction
situations, it won't stop any faster than
two-wheel drive vehicles. Always drive at
a safe speed.
Truck and utility vehicles can differ from
some other vehicles. Your vehicle could be
higher to allow it to travel over rough terrain
without getting stuck or damaging
underbody components. The differences that
make your vehicle so versatile also make it
handle differently than an ordinary passenger
car. Always maintain steering wheel control,
especially in rough terrain. Since sudden
changes in terrain can result in abrupt
steering wheel motion, make sure you grip
the steering wheel from the outside. Do not
grip the spokes. Drive cautiously to avoid
vehicle damage from concealed objects such as rocks and stumps. Drive slower in strong
crosswinds which can affect the normal
steering characteristics of your vehicle. Be
extremely careful when driving on pavement
made slippery by loose sand, water, gravel,
snow or ice.
Note:
Do not use four-wheel drive high or
four-wheel drive low mode on dry, hard
surfaced roads. Doing so can produce
excessive noise, increase tire wear and can
damage drive components.
FOUR-WHEEL DRIVE LIMITATIONS
Operating Four-Wheel Drive with a
Spare or Mismatched Tires
(If Equipped)
On four-wheel drive vehicles, the size of the
spare tire can affect the four-wheel drive
system. If there is a significant difference
between the size of the spare tire and the
remaining tires, you could have limited
four-wheel drive functionality. When driving
with the full-size dissimilar spare wheel and
tire assembly, we recommend that you do
not: •
Exceed
50 mph (80 km/h) with a
four-wheel drive mode turned on.
• Use a four-wheel drive mode on dry
pavement.
Driving with the full-size dissimilar spare
wheel and tire assembly can limit four-wheel
drive functionality. You can experience the
following:
• Additional noise from the transfer case
or other drive components.
Use of a dissimilar spare wheel and tire
assembly can lead to impairment of the
following:
• Comfort and noise.
• Winter weather driving capability.
• Wet driving capability.
• Four-wheel drive capability.
Note: Your vehicle could have a front air
dam that can become damaged, due to
reduced ground clearance, when taking your
vehicle off-road. You can remove this air
dam by removing the eight bolts that secure
it.

Note:
Your vehicle could have side steps
that can become damaged, due to reduced
ground clearance, when taking your vehicle
off-road. Remove side steps before driving
your vehicle off-road.
SELECTING A FOUR-WHEEL DRIVE
MODE
To select a specific four-wheel drive mode
please select one of the desired drive
modes. For additional information. See
Selecting a Drive Mode (page 294).
Note: When shifting to and from four-wheel
drive information display will show shifting
in progress message indicating that the
system is in the process of making a shift.
Note: Do not perform this operation if the
rear wheels are slipping or while applying
the accelerator pedal.
If the system detects a fault, a warning
message appears in the information display.
See
Four-Wheel Drive – Information
Messages (page 229). Note:
Do not use SLIPPERY, DEEP
CONDITIONS or SLOW CLIMB on dry, hard
surfaced roads. Doing so produces
excessive noise, increases tire wear and may
damage drive components. The 4X4 system
in these modes is only intended for
consistently slippery or loose surfaces.
Shifting to or from Slow Climb (4L)
To select or exit SLOW CLIMB (4L):
1. Bring your vehicle to a speed of
3.1 mph
(5 km/h) or less.
2. Place the transmission in neutral (N).
3. Select SLOW CLIMB on the drive mode control switch.
The information display will display a
message indicating a four-wheel drive shift
is in progress. If any of the above shift
conditions are not present, the shift will not
occur and the information display will display
information guiding the driver through the
proper shifting procedures. If there is a
transfer case tooth blockage a message will display in the information display. To alleviate
this condition, place the transmission in a
forward gear, move your vehicle forward
approximately
4.9 ft (1.5 m), and shift the
transmission back to neutral (N) to allow the
transfer case to complete the range shift.
Note: You could hear some noise as the
system shifts or engages which is normal. If
the system detects a fault, a warning
message appears in the information display.
See
Four-Wheel Drive – Information
Messages (page 229).
FOUR-WHEEL DRIVE MODES
TWO-WHEEL DRIVE HIGH
2H turns on when you select NORMAL or
CONSERVE. Two-wheel drive high is for
general on-road driving. Power is sent to the
rear wheels only.
Note: Two-wheel drive high can turn on or
off based on Drive Mode selection See Drive
Mode Control
(page 293).

The usage of a full-size dissimilar spare
wheel and tire assembly can lead to
impairment of the following:
•
Handling, stability and braking
performance.
• Comfort and noise.
• Ground clearance and parking at curbs.
• Winter weather driving capability. •
Wet weather driving capability.
• Four-wheel driving capability.
When driving with the full-size dissimilar
spare wheel and tire assembly additional
caution should be given to:
• Towing a trailer.
• Driving vehicles with a camper body.
• Driving vehicles with a load on the cargo
rack. Drive cautiously when using a full-size
dissimilar spare wheel and tire assembly and
seek service as soon as possible.
