Modes for Hilux4x4
I thought it would be
useful to copy the following from the Hilux Manual. Albeit from
the 2700i 4x4 DC, it is applicable to the SFA models as well.
Speeds with 3RZ-FE (2700i) engine - "L4"
1st Gear - 16km/hr
2nd Gear - 30km/hr
3rd Gear - 47km/hr
4th Gear - 60km/hr
Speeds with 5L (3000 Diesel) engine - "L4"
1st Gear - 13km/hr
2nd Gear - 22km/hr
3rd Gear - 36km/hr
4th Gear - 52km/hr
Do not downshift if you are going faster than the maximum allowable
speed for the next lower gear.
Be careful when downshifting on a slippery surface. Abrupt shifting
could cause the vehicle to spin or skid out of control.
Use the Transfer Control
Lever to select the following transfer modes:
Speed position, two-wheel drive):
Use this for normal driving on dry hard surfaced roads. This position
gives greater economy, quietest ride and least wear.
"H4 (High Speed
position, four-wheel drive):
LEVER at "H4"
Use this for normal driving on wet or icy covered roads. This position
provides greater traction than two-wheel drive.
LEVER at "N"
No power is delivered to the wheels. The vehicle must be stopped.
"L4" (Low Speed
position, four-wheel drive):
LEVER at "L4"
Use this for maximum power and traction. Use "L4" for
climbing or descending steep hills, off-road driving and hard pulling
in sand or mud.
The four-wheel drive
indicator light comes on when the "H4", "N"
or "L4" mode is selected.
See "Shifting procedure"
for further instructions.
BETWEEN "H2" AND "H4"
To shift from "H2"
to "H4", move the transfer control lever. Also remember
to engage both the free-wheeling hubs.
Transfer from "H2"
to "H4" can be done when the vehicle is stopped or moving
straight ahead at speeds of 40Km/Hr or less. You need not depress
the Clutch Pedal. If you have trouble shifting, depress or release
the accelerator pedal for a moment while pushing the transfer control
Do not move the transfer control lever if wheels are slipping or
spinning before shifting.
Do not drive with only one hub engaged.
To shift from
"H4" to "H2", simply move the front drive control
lever. Also, remember to disengage both free-wheeling hubs for continued
The shifting from "H4"
to "H2" can be done at any vehicle speed. You need not
depress the clutch pedal.
If the indicator light
does not go off when you shift the transfer into "H2",
drive straight ahead while accelerating or decelerating, or drive
The photo below is from
my 1987 Hilux DC.
To engage the free-wheeling
hubs, turn the centre disc to "LOCK" (on the front wheels)
To disengage, turn the
centre disc to "FREE".
Setting the free-wheeling
hubs in "FREE" disengages the front axle and driveshaft
so that they are not revolving.
This reduces noise and
wear when the vehicle is in two-wheel drive.
You should drive with
the hubs in "LOCK" for at least 16km each month. This
will assure that the front drive components are lubricated.
some further notes printed on a card attached to the rear of the
driver's sun visor:
GEAR SHIFTING INSTRUCTIONS
1. Normal driving on
dry, hard-surfaced roads, use "H2" position.
2. ADD (Automatic Disconnecting
Differential) models "H2" -> "H4":
* Keep Vehicle speed below 80km/Hr
* In cold weather, if shifting is hard, reduce speed or stop the
vehicle, then try to shift again.
3. Free-wheel hub models:
Before shifting to "H4" or "L4", always set
both hubs at "Lock" position.
4. "H2" ->
"H4": If the Indicator light does not go off, drive straight
ahead while accelerating or decelerating, or drive in Reverse.
5. "H4" <-->
* Depress the Clutch Pedal.
* "H4" -> "L4": Stop the vehicle, or keep
the vehicle speed below 8Km/Hr.
* Stop the vehicle, then
shift the transmission into "N" first.
6. 4WD Vehicle Emergency
Refer to Owner's Manual or repair Manual for "Towing Information".
(This states that if
the vehicle is towed, then the wheels which are connected to a Diff
should always be lifted off the ground and placed on a trolley,
i.e. the tyres can not rotate while being towed.
