Grass-Gravel-Snow (firm base slippery top):

If Low Range is selected, ride height is raised and Hill Descent Control is activated
Differentials are locked.
Engine pickup is softer, reducing sudden bursts of power.
Auto transmission upshifts early.
Sets off in Second Gear, High Range or Third Gear, Low Range
Stability systems primed to cut any slip or slide

Mud-Ruts (soft uneven muddy ground, wet and soggy sand):

Hill Descent Control is selected
Differentials are partly locked
Low Range is preferred, but not automatically recommended
If Low Range selected, ride height is raised (NB requires manual activation if trailer attached)
Transmission shifts early, remaining in higher gears for longer

Sand (soft and dry also deep gravel):

If Low Range selected, ride height is raised (NB requires manual activation if trailer attached)
Throttle is responsive to acceleration
Transmission downshifts readily
Traction and stability systems allow for increased wheel slip
Switch off DSC if extremely soft and dry

Rock Crawl (wet or dry solid unyielding ground – Rocky river crossings):

Low range must be selected
Differentials are locked
Ride height is raised (NB requires manual activation if trailer attached)
Slowest speed for Hill Descent Control is selected
Allows extreme suspension articulation
Sets off in first gear
Stability systems primed to cut any slip or slide

Hill Descent Control:

High Range: D, R and CommandShift 1
Low Range: D, R and ALL CommandShift gears
Fully functional below 50kph
Descent speed controlled by Cruise Control + or – (press and hold until desired speed)

Low Range / High Range:

Stationary:
apply foot brake
transmission to N (neutral)
activate transfer gear switch
transmission to D
On Move – High to Low: No faster than 40kph
transmission to N
push transfer gear switch to LOW and release
transmission to D. Gear won’t be selected until range change is completed.
On Move – Low to High: No faster than 60kph
transmission to N
pull transfer gear switch to HIGH and release
transmission to D. Gear won’t be selected until range change is completed.
