2010 DODGE NITRO four wheel drive

31. 4WD Indicator — If Equipped
This light indicates the vehicle is in four-wheel
drive and 4LOCK. 4WD allows all four wheels to
receive torque from the engine simultaneously.
COMPASS AND TRIP COMPUTER — IF
EQUIPPED
The Compass/Trip Computer features a driver-
interactive display (displays information on outside tem-
perature, compass direction, and trip information). It is
located on the lower left part of the cluster below the fuel
and engine temperature gauge, and the tachometer.
Control Buttons
Press and release the odometer/trip odometer reset but-
ton (right side of the instrument cluster) to access the
compass/trip computer displays.

292 STARTING AND OPERATING

•If the vehicle has not been driven in several days, the
first few seconds of operation after shifting the trans-
mission into gear may seem sluggish. This is due to the
fluid partially draining from the torque converter into
the transmission. This condition is normal and will not
cause damage to the transmission. The torque con-
verter will refill within five seconds of shifting from
PARK into any other gear position.
FOUR-WHEEL DRIVE OPERATION — IF

MP 143 Single-Speed Part-Time Transfer Case
Operating Information/Precautions
The transfer case is operated by the transfer case switch
(located on the center console).The electronically shifted transfer case provides two
mode positions:
•Two-wheel drive high range (2WD)
•Four-wheel drive high range (4WD LOCK)
Transfer Case Switch
308 STARTING AND OPERATING

The electronically shifted transfer case is designed to be
driven in the two-wheel drive position (2WD) for normal
street and highway conditions (dry hard surfaced roads).
When additional traction is required, the transfer case
4WD LOCK position can be used to lock the front and
rear driveshafts together and force the front and rear
wheels to rotate at the same speed. This is accomplished
by rotating the transfer case switch to the desired posi-
tion. Refer to “Shifting Procedure” for specific shifting
instructions. The 4WD LOCK position is designed for
loose, slippery road surfaces only.
CAUTION!
•Driving in the 4WD LOCK position on dry hard
surfaced roads may cause increased tire wear and
damage to the driveline components.(Continued)
CAUTION! (Continued)
•Do not attempt to make a shift while only the front
or rear wheels are spinning. Shifting while only
the front or rear wheels are spinning can cause
damage to the transfer case.
Proper operation of four-wheel drive vehicles depends
on tires of equal size, type and circumference on each
wheel. Any difference in tire size can cause damage to the
transfer case. Tire rotation schedule should be followed
to balance tire wear.
Since four-wheel drive provides improved traction, there
is a tendency to exceed safe turning and stopping speeds.
Do not go faster than road conditions permit.

STARTING AND OPERATING 309

Shifting Procedure – Electronically Shifted
Transfer Case
NOTE:If any of the requirements to select a new
transfer case position have not been met, the transfer case
will not shift. The “4WD Indicator Light” (located in the
display under the tachometer) will flash until all the
requirements for the selected position have been met. To
retry a shift, return the control knob back to the original
position, make certain all shift requirements have been
met, wait five seconds and try the shift again.
2WD⇔ 4WD LOCK
Rotate the transfer case switch to the desired position.
Shifts between 2WD and 4WD LOCK can be done with
the vehicle stopped or in motion. With the vehicle in
motion, the transfer case will engage/disengage faster if
you momentarily release the accelerator pedal after turn-
ing the switch. If the vehicle is stopped, the ignition key must be in the ON position with the engine either
RUNNING or OFF. This shift cannot be completed if the
key is in the ACC position.
NOTE:
•The four-wheel drive system will not allow shifts
between 2WD/4WD LOCK if the front and/or rear
wheels are spinning (no traction). In this situation, the
“4WD Indicator Light” (located in the display under
the tachometer) will flash. At this time, reduce speed
and stop spinning the wheels to complete the shift.
•Delayed shifting out of 4WD LOCK may be experi-
enced due to uneven tire wear, low tire pressure, or
excessive loading.
ON-ROAD DRIVING TIPS
Utility vehicles have higher ground clearance and a
narrower track to make them capable of performing in a
wide variety of off-road applications. Specific design
310 STARTING AND OPERATING

drive through water, try to determine the depth and the
bottom condition (and location of any obstacles) prior to
entering. Proceed with caution and maintain a steady
controlled speed less than 5 mph (8 km/h) in deep water
to minimize wave effects.
Flowing Water
If the water is swift flowing and rising (as in storm
run-off) avoid crossing until the water level recedes
and/or the flow rate is reduced. If you must cross
flowing water, avoid depths in excess of 9 in (23 cm). The
flowing water can erode the streambed causing your
vehicle to sink into deeper water. Determine exit point(s)
that are downstream of your entry point to allow for
drifting.Standing Water
Avoid driving in standing water deeper than 20 in
(50 cm) and reduce speed appropriately to minimize
wave effects. Maximum speed in 20 in (50 cm) of water is
less than 5 mph (8 km/h).
Maintenance
After driving through deep water, inspect your vehicle
fluids and lubricants (engine, transmission, axle, transfer
case) to assure they have not been contaminated. Con-
taminated fluids and lubricants (milky, foamy in appear-
ance) should be flushed/changed as soon as possible to
prevent component damage.
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 transfer case to 4L or 4LO if necessary.
Refer to “Four-Wheel Drive Operation” in “Starting and
Operating” for further information. Do not shift to a
312 STARTING AND OPERATING

Traction Downhill
Shift the transmission into a low gear and the transfer
case to 4L or 4LO range. Let the vehicle go slowly down
the hill with all four wheels turning against engine
compression drag. This will permit you to control the
vehicle speed and direction.
When descending mountains or hills, repeated braking
can cause brake fade with loss of braking control. Avoid
repeated heavy braking by downshifting the transmis-
sion whenever possible.
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, and
exhaust system for damage.
•Inspect the radiator for mud and debris and clean as
required.
•Check threaded fasteners for looseness, particularly on
the chassis, drivetrain components, steering, and sus-
pension. 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.
