The transfer case 4WD shift switch is used to
select either 2WD or 4WD depending on the
driving conditions. There are four types of drive
modes available, AUTO, 2WD, 4H and 4LO.
The 4WD shift switch electronically controls the
transfer case operation. Rotate the switch to
move between each mode, 2WD, AUTO, 4H and
4LO.
You must push the switch in to select 4LO,
and the vehicle MUST be stationary and the
automatic transmission selector lever in
the N position when changing into or out of
4LO.
WARNING
When parking, apply the parking brake
before stopping the engine and make sure
that the 4WD shift indicator light is on and
the ATP warning light goes off. Otherwise,
the vehicle could unexpectedly move even
if the automatic transmission is in the P
position.
CAUTION
●
Never shift the 4WD shift switch be-
tween 4LO and 4H while driving.
●
The 4H position provides greater trac-
tion. Avoid excessive speed, as it will
cause increased fuel consumption and
higher oil temperatures, and could
damage
drivetrain
components.
Speeds over 62.5 MPH (100 km/h) in 4H
is not recommended.
●
The 4LO position provides maximum
power and traction. Avoid raising ve-
hicle speed excessively, as the maxi-
mum speed is approximately 31 MPH
(50 km/h).
●
When driving straight, shift the 4WD
shift switch to the 2WD, AUTO or 4H
position. Do not move the 4WD shift
switch when making a turn or reversing.
●
Do not shift the 4WD shift switch (be-
tween 2WD, AUTO and 4H) while driving
on steep downhill grades. Use the en-
gine brake and low automatic transmis-
sion gears (D1 or D2) for engine
braking.
●
Do not operate the 4WD shift switch
(between 2WD, AUTO and 4H) with the
rear wheels spinning.
●
Do not drive on dry hard surface roads
in the 4H or 4LO position. Driving on dry
hard surfaces in 4H or 4LO may cause
unnecessary noise and tire wear. IN-
FINITI recommends driving in the 2WD
or
AUTO
position
under
these
conditions.
●
The 4WD transfer case may not be
shifted between 4H and 4LO at low am-
bient temperatures and the transfer
4LO position indicator light may blink
even when the 4WD shift switch is
shifted. After driving for a while you can
change the 4WD transfer case between
4H and 4LO.
When driving on rough roads,
●
Set the 4WD shift switch to AUTO, 4H or
4LO.
●
Drive carefully according to the road surface
conditions.
When the vehicle is stuck,
●
Set the 4WD shift switch to 4H or 4LO.
●
If it is difficult to free the vehicle, repeat
forward and backward movement to in-
crease the movement.
