Ford Ranger Owner's Handbook Manual page 70

Note: Driving in two-wheel drive 2H with
the RFW lock activated will result in
greater tyre resistance, increased fuel
consumption and unnecessary noise.
Use for all normal road driving and also for
off-road driving across dry, level terrain.
Four-wheel drive, high range (4H)
CAUTIONS
Do not use four-wheel drive 4H for
normal road driving.
Do not exceed 100 km/h (62 mph).
Use for off-road driving.
Four-wheel drive, low range (4L)
CAUTIONS
Do not use four-wheel drive 4L for
normal road driving.
Do not exceed 40 km/h (25 mph).
Use for more extreme off-road conditions,
such as steep ascents and descents.
Also use when low speed manoeuvring
is necessary, such as reversing a trailer
or negotiating a boulder-strewn river bed,
or when moving off while heavily loaded
or towing. This will prevent prolonged
slipping of the clutch.
Neutral (N)
Use for shifting between ranges.
Changing range
Depress the clutch pedal and shift the
selector lever to the relevant position.
Transmission
Shifting between (2H) and (4H)
Do not shift the selector lever
between 2H and 4H with the
remote free-wheel lock deactivated
and the vehicle moving. This can damage
the drive assembly.
This can be done with the vehicle moving
when the remote free-wheel (RFW) lock
indicator lamp is on. See Warning
lamps and indicators (page 44).
Shifting between (4H) and (4L)
Do not shift the selector lever
between 4H and 4L with the vehicle
moving. This can damage the drive
assembly.
1. Stop the vehicle when it is safe to do
so.
2. Shift the selector lever from 4H to 4L
or from 4L to 4H.
Shifting between (4H) and (2H)
This can be done with the vehicle moving.
