Electronic Range Select (ERS) Operation
The Electronic Range Select (ERS) shift control allows the
driver to limit the highest available gear when the trans-
mission is in DRIVE. For example, if you set the transmis-
sion gear limit to 4 (fourth gear), the transmission will not
shift above fourth gear, but will shift through the lower
gears normally.
You can switch between DRIVE and ERS mode at any
vehicle speed. When the gear selector is in the DRIVE
position, the transmission will operate automatically, shift-
ing between all available gears. Tapping the ERS (-) switch
will activate ERS mode, display the current gear in the
instrument cluster, and set that gear as the top available
gear. Once in ERS mode, tapping (-) or (+) will change the
top available gear.To exit ERS mode, simply push and hold the ERS (+) switch
until the gear limit display disappears from the instrument
cluster.
WARNING!
Do not downshift for additional engine braking on a
slippery surface. The drive wheels could lose their grip
and the vehicle could skid, causing a collision or
personal injury.

Pushing the “Up” button once will move the suspension
one position higher from the current position, assuming all
conditions are met (i.e. key in ON/RUN position, engine
running, speed below threshold, etc). The “Up” button can
be pushed multiple times, each push will raise the re-
quested level by one position up to a maximum position of
OR or the highest position allowed based on current
conditions (i.e. vehicle speed, etc).
Pushing the “DOWN” button once will move the suspen-
sion one position lower from the current level, assuming all
conditions are met (i.e. key in ON/RUN position, engine

and ice. Every surface has a different effect on your
vehicle’s steering, handling and traction. Controlling your
vehicle is one of the keys to successful off-road driving, so
always keep a firm grip on the steering wheel and maintain
a good driving posture. Avoid sudden accelerations, turns
or braking. In most cases there are no road signs, posted
speed limits or signal lights. Therefore you will need to use
your own good judgment on what is safe and what isn’t.
When on a trail you should always be looking ahead for
surface obstacles and changes in terrain. The key is to plan
your future driving route while remembering what you are
currently driving over.
CAUTION!
Never park your vehicle over dry grass or other com-
bustible materials. The heat from your vehicle exhaust
system could cause a fire.
WARNING!
Always wear your seat belt and firmly tie down cargo.
Unsecured cargo can become projectiles in an off-road
situation.
When To Use Low Range
When driving off-road, shift into 4LO (Low Range) for
additional traction or to improve handling and control on
slippery or difficult terrain. Due to the lower gearing, low
range will allow the engine to operate in a higher power
range. This will allow you to idle over obstacles and down
hills, with improved control and less effort. Also, use 4LO
(Low Range) in rain, ice, snow, mud, sand, to get heavy
loads rolling, improve traction, or whenever 4HI (High
Range) traction will not do the job.
Driving In Snow, Mud And Sand
There is a drastic reduction in traction when driving in
snow, mud or sand. The vehicle will be less responsive to
steering, acceleration and braking inputs. Therefore you
should accelerate slowly, leave greater stopping distances
and avoid abrupt vehicle maneuvers. You want to keep a
slow constant steady pace. The key is to maintain the
vehicle’s momentum.
•Snow – In heavy snow or for additional control and
traction at slower speeds, shift the transmission to a low
gear and shift the transfer case to 4LO (Low Range) if
necessary. Do not shift to a lower gear than necessary to
maintain headway. Over-revving the engine can spin the
wheels and traction will be lost. If you start to slow to a

Hill Climbing
Hill climbing requires good judgment and a good under-
standing of your abilities and your vehicle’s limitations.
Hills can cause serious problems. Some are just too steep to
climb and should not be attempted. You should always feel
confident with the vehicle and your abilities. You should
always climb hills straight up and down. Never attempt to
climb a hill on an angle.
•Before Climbing A Steep Hill – As you approach a hill
consider its grade or steepness. Determine if it is too
steep. Look to see what the traction is on the hill side
trail. Is the trail straight up and down? What is on top
and the other side? Are there ruts, rocks, branches or
other obstacles on the path? Can you safely recover the
vehicle if something goes wrong? If everything looks
good and you feel confident, then change transmission
into a lower gear, shift the transfer case into 4LO (Low)
and proceed with caution. You should use first gear and
4LO (Low Range) for very steep hills.
• Driving Up Hill – Once you have determined your
ability to proceed and have shifted into the appropriate
gear, line your vehicle up for the straightest possible run.
Accelerate with an easy constant throttle and apply
more power as you start up the hill. Do not race forward into a steep grade, the abrupt change of grade could
cause you to lose control. If the front end begins to
bounce, ease off the throttle slightly to bring all four tires
back on the ground. As you approach the crest of the hill
ease off the throttle and slowly proceed over the top. If
the wheels start to slip as you approach the crest of a hill,
ease off the accelerator and maintain headway by turn-
ing the steering wheel no more than a ¼ turn quickly
back and forth. This will provide a fresh
biteinto the
surface and will usually provide enough traction to
complete the climb. If you do not make it to the top,
place the vehicle in REVERSE and back straight down
the grade using engine resistance along with the vehicle
brakes.
WARNING!
Never attempt to climb a hill at an angle or turn around
on a steep grade. Driving across an incline increases
the risk of a roll over, which may result in severe injury
or death.
• Driving Down Hill – Before driving down a steep hill
you need to determine if it is too steep for a safe descent.
What is the surface traction? Is the grade too steep to
maintain a slow controlled descent? Are there obstacles?
