STARTING AND OPERATING229
OVER THE ROAD OPERATION WITH 
S
NOWPLOW ATTACHED
The blade restricts air flow to the radiator and 
causes the engine to operate at higher than 
normal temperatures. Therefore, when 
transporting the plow, angle the blade 
completely and position it as low as road or 
surface conditions permit. Do not exceed 
40 mph (64 km/h). The operator should always 
maintain a safe stopping distance and allow 
adequate passing clearance.
OPERATING TIPS
Under ideal snow plowing conditions, 20 mph 
(32 km/h) should be maximum operating 
speed. The operator should be familiar with the 
area and surface to be cleaned. Reduce speed 
and use extreme caution when plowing 
unfamiliar areas or under poor visibility.
GENERAL MAINTENANCE
Snowplows should be maintained in 
accordance with the plow manufacturer's 
instructions.
Keep all snowplow electrical connections and 
battery terminals clean and free of corrosion.
When plowing snow, to avoid transmission and 
drivetrain damage, the following precautions 
should be observed:
Operate with transfer case in 4WD Low when 
plowing small or congested areas where 
speeds are not likely to exceed 15 mph 
(24 km/h). At higher speeds operate in 4WD 
High.
Vehicles with automatic transmissions 
should use 4WD Low when plowing deep or 
heavy snow for extended periods of time to 
avoid transmission overheating.
Do not shift the transmission unless the 
engine has returned to idle and wheels have 
stopped. Make a practice of stepping on the 
brake pedal while shifting the transmission.

TOWING THIS VEHICLE BEHIND ANOTHER VEHICLE
NOTE:
When towing your vehicle, always follow 
applicable state and provincial laws. Contact 
state and provincial Highway Safety offices 
for additional details.
Vehicles equipped with Active-Level Four 
Corner Air Suspension must be placed in 
Transport mode before tying them down 
(from the body) on a trailer or flatbed truck  
Úpage 165. If the vehicle cannot be placed 
in Transport mode (for example, engine will 
not run), tie-downs must be fastened to the  axles (not to the body). Failure to follow these 
instructions may cause fault codes to be set 
and/or cause loss of proper tie-down tension.
RECREATIONAL TOWING — TWO-WHEEL 
D
RIVE MODELS

F
OUR-WHEEL DRIVE MODELS
NOTE:
The transfer case must be shifted into N 
(Neutral) for recreational towing. The transmis -
sion must be shifted into PARK for recreational 
towing. Refer to the following for the proper 
transfer case N (Neutral) shifting procedure for 
your vehicle.
CAUTION!
Towing with the rear wheels on the ground will 
cause severe transmission damage. Damage 
from improper towing is not covered under 
the New Vehicle Limited Warranty.
CAUTION!
DO NOT dolly tow any 4WD vehicle. Towing 
with only one set of wheels on the ground 
(front or rear) will cause severe transmis -
sion and/or transfer case damage. Tow 
with all four wheels either ON the ground, or 
OFF the ground (using a vehicle trailer).
Tow only in the forward direction. Towing 
this vehicle backwards can cause severe 
damage to the transfer case.
Before recreational towing, the transfer 
case must be in N (Neutral). To be certain 
the transfer case is fully in N (Neutral), 
perform the procedure outlined under 
“Shifting Into N (Neutral)”. Internal trans -
mission damage will result, if the transfer 
case is not in N (Neutral) during towing.
The transmission must be in PARK for 
recreational towing.
Ensure that the Electric Park Brake is 
released, and remains released, while 
being towed.
Towing this vehicle in violation of the above 
requirements can cause severe transmis -
sion and/or transfer case damage. 
Damage from improper towing is not 
covered under the New Vehicle Limited 
Warranty.
Do not disconnect the rear driveshaft 
because fluid will leak from the transfer 
case, causing damage to internal parts.
Do not use a bumper-mounted clamp-on 
tow bar on your vehicle. The bumper face 
bar will be damaged.

232STARTING AND OPERATING  
Shifting Into N (Neutral) 
Use the following procedure to prepare your 
vehicle for recreational towing.
 1. Bring the vehicle to a complete stop on 
level ground, with the engine running. 
Apply the parking brake.
2. Press and hold the brake pedal.
3. Shift the transmission to NEUTRAL. The  driver's door must be closed (or the driver's 
seat belt buckled) so that the transmission 
will remain in NEUTRAL when the brake 
pedal is released.
NOTE:
If vehicle is equipped with air suspension, 
ensure the vehicle is set to Normal Ride Height.
4. Using a ballpoint pen or similar object, push  and hold the recessed transfer case N 
(Neutral) button (at the center of the 
transfer case switches). The N (Neutral) 
indicator light will illuminate, and remain lit, 
when the shift to N (Neutral) is complete. 
After the shift is completed and the N 
(Neutral) light stays on, release the N 
(Neutral) button.
5. Release the parking brake. 6. Shift the transmission into REVERSE.
7. Release the brake pedal for five seconds 
and ensure that there is no vehicle 
movement.
8. Repeat steps 6 and 7 with the transmission  in DRIVE.
9. Shift the transmission to NEUTRAL. Apply  the parking brake. Turn off the engine. For 
vehicles with Keyless Enter-N-Go, push and 
hold the ENGINE START/STOP button until 
the engine shuts off. The transmission will 
automatically select PARK when the engine 
is turned off.
10. Turn the ignition off.
11. Attach the vehicle to the tow vehicle using a  suitable tow bar.
12. Turn the ignition to the ON/RUN mode, but  do not start the engine.
13. Release the parking brake.
14. Turn the ignition OFF.
WARNING!
You or others could be injured or killed if you 
leave the vehicle unattended with the transfer 
case in the N (Neutral) position without first 
fully engaging the parking brake. The transfer 
case N (Neutral) position disengages both the 
front and rear driveshafts from the power -
train and will allow the vehicle to roll, even if 
the transmission is in PARK. The parking 
brake should always be applied when the 
driver is not in the vehicle.
CAUTION!
It is necessary to follow these steps to be cer -
tain that the transfer case is fully in N (Neu -
tral) before recreational towing to prevent 
damage to internal parts.

met before pushing the button to shift out of 
N (Neutral), and must continue to be met 
until the shift has been completed. If any of 
these requirements are not met before 
pushing the button or are no longer met 
during the shift, the N (Neutral) indicator light 
will flash continuously until all requirements 
are met or until the button is released.
The ignition must be in the ON/RUN mode for 
a shift to take place and for the position indi -
cator lights to be operable. If the ignition is 
not in the ON/RUN mode, the shift will not 
take place and no position indicator lights will 
be on or flashing.
A flashing N (Neutral) position indicator light 
indicates that shift requirements have not 
been met.

DRIVING TIPS
DRIVING ON SLIPPERY SURFACES 
Acceleration
Rapid acceleration on snow covered, wet, or 
other slippery surfaces may cause the driving 
wheels to pull erratically to the right or left. This 
phenomenon occurs when there is a difference 
in the surface traction under the rear (driving) 
wheels.
DRIVING THROUGH WATER 
Driving through water more than a few inches/
centimeters deep will require extra caution to 
ensure safety and prevent damage to your 
vehicle.
Flowing/Rising Water
Shallow Standing Water
Although your vehicle is capable of driving 
through shallow standing water, consider the 
following Cautions and Warnings before doing 
so.
WARNING!
Rapid acceleration on slippery surfaces is 
dangerous. Unequal traction can cause sud
-
den pulling of the rear wheels. You could lose 
control of the vehicle and possibly have a col -
lision. Accelerate slowly and carefully when -
ever there is likely to be poor traction (ice, 
snow, wet, mud, loose sand, etc.).
WARNING!
Do not drive on or across a road or path 
where water is flowing and/or rising (as in 
storm run-off). Flowing water can wear away 
the road or path's surface and cause your 
vehicle to sink into deeper water. Further -
more, flowing and/or rising water can carry 
your vehicle away swiftly. Failure to follow this 
warning may result in injuries that are serious 
or fatal to you, your passengers, and others 
around you.
WARNING!
Driving through standing water limits your 
vehicle’s traction capabilities. Do not 
exceed 5 mph (8 km/h) when driving 
through standing water.
Driving through standing water limits your 
vehicle’s braking capabilities, which 
increases stopping distances. Therefore, 
after driving through standing water, drive 
slowly and lightly press on the brake pedal 
several times to dry the brakes.
Failure to follow these warnings may result 
in injuries that are serious or fatal to you, 
your passengers, and others around you.
CAUTION!
Always check the depth of the standing 
water before driving through it. Never drive 
through standing water that is deeper than 
the bottom of the tire rims mounted on the 
vehicle.
Determine the condition of the road or the 
path that is under water and if there are any 
obstacles in the way before driving through 
the standing water.
Do not exceed 5 mph (8 km/h) when 
driving through standing water. This will 
minimize wave effects.

STARTING AND OPERATING235
OFF-ROAD DRIVING TIPS  
Care should be taken when attempting to climb 
steep hills or driving diagonally across a hill or 
slope. If natural obstacles force you to travel 
diagonally up or down a hill, choose a mild angle 
and keep as little side tilt as possible. Keep the 
vehicle moving and make turns slowly and 
cautiously. If you must back down a hill, back straight down 
using REVERSE gear. Never back down in 
NEUTRAL or diagonally across the hill.
When driving over sand, mud, and other soft 
terrain, shift to low gear and drive steadily. 
Apply the accelerator slowly to avoid spinning 
the wheels.
Do not reduce the tire pressures for this type of 
driving.
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 compo
-
nents, 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.
If you experience unusual vibration after 
driving in mud, slush or similar conditions, 
check the wheels for impacted material. 
Impacted material can cause a wheel imbal-
ance and freeing the wheels of it will correct 
the situation.
Driving through standing water may cause 
damage to your vehicle’s drivetrain compo -
nents. Always inspect your vehicle’s fluids 
(i.e., engine oil, transmission, axle, etc.) for 
signs of contamination (i.e., fluid that is 
milky or foamy in appearance) after driving 
through standing water. Do not continue to 
operate the vehicle if any fluid appears 
contaminated, as this may result in further 
damage. Such damage is not covered by 
the New Vehicle Limited Warranty.
Getting water inside your vehicle’s engine 
can cause it to lock up and stall out, and 
cause serious internal damage to the 
engine. Such damage is not covered by the 
New Vehicle Limited Warranty.
CAUTION!  (Continued)
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.
