Ignitionswitch,etc. -> Four-wheel drive system for Your Toyota 4 Runner SUV Third Generation (1996-2002)

’01 4Runner_U (L/O 0008)  
Four−wheel drive system—  
(a) Front drive control  
(k) If you cannot shift the selector le-  
ver out of “P” position  
Use the front drive control lever, “4WD”  
button and center differential lock  
switch to select the transfer and center  
differential modes.  
If you cannot shift the selector lever from  
the “P” position even though the brake  
pedal is depressed, use the shift lock  
override lever. For instructions, see “If you  
cannot shift automatic transmission selec-  
tor lever” in Section 4.  
The “H” and “L4” position of the front  
drive control lever provide either lock or  
unlock the mode of the center differential.  
Use the center differential lock system if  
your wheels get stuck in a ditch, or when  
you are driving on a slippery or bumpy  
surface. When the center differential is  
locked, the vehicle skid control system is  
automatically turned off and the center dif-  
ferential lock and “VSC OFF” indicator  
lights come on because the function that  
controls engine performance interferes  
with the process of freeing your wheels.  
“H” (2WD) MODE  
NOTICE  
“H” (4WD) MODE (center  
differential unlock), “L4”  
MODE (center differential  
unlock) or “N” MODE  
As soon as the center differential lock  
switch is turned on, the “VSC OFF”  
indicator light comes on. After the  
wheels are out of the ditch or off the  
slippery or bumpy surface, turn the  
center differential lock switch off.  
Make sure that the center differential  
lock indicator light and “VSC OFF”  
indicator light turn off.  
“H” (4WD) MODE (center  
differential lock), “L4”  
MODE (center differential  
lock) or “N” MODE

“H” mode (high speed position, two−  
wheel drive): Front drive control lever at  
“H”, “4WD” button left out  
“N” mode (neutral position): Front drive  
control lever at “N”  
No power is delivered to the wheels. The  
vehicle must be stopped.  
“L4” mode (low speed position, four−  
wheel drive, center differential locked):  
Front drive control lever at “L4”, center  
differential lock switch push in  
Use this for maximum power and traction.  
Use this for hard pulling in situations the  
vehicle cannot negotiate even in the “L4”  
(low speed position, four−wheel drive, cen-  
ter differential unlocked) mode. Also, using  
this mode when driving down steep off−  
road inclines will help contribute to in-  
creased vehicle stability.  
Use this for normal driving on dry hard−  
surfaced roads. This position gives greater  
economy, quietest ride and least wear and  
better vehicle control.  
“L4” (low speed position, four−wheel  
drive, center differential unlocked):  
Front drive control lever at “L4”, center  
differential lock switch left out  
Use this for maximum power and traction.  
Use this for climbing steep hills, off−road  
driving, and hard pulling in sand or mud.  
“H” mode (high speed position, four−  
wheel drive, center differential un-  
locked): Front drive control lever at “H”,  
“4WD” button push in, center differential  
lock switch left out  
In this mode, the braking feeling that oc-  
curs when the wheels are negotiating a  
sharp corner is further reduced than in the  
“L4” (low position, four−wheel drive, center  
differential locked) mode.  
Use this for normal driving on all types of  
roads, from dry hard−surfaced roads to  
wet, icy or snow−covered roads. This  
position provides greater traction than  
two−wheel drive.  
Four−wheel drive and center differential  
lock indicator lights show which transfer  
and center differential mode the vehicle is  
in. Note that the differential is not still  
locked as long as the indicator light re-  
mains off.  
The transmission automatically shifts up  
from second gear in this mode. This sys-  
tem is effective when starting your vehicle  
in sand, mud, ice or snow. (However, the  
transmission system may shift up from  
first gear when the vehicle starts too  
quickly.)  
“H” (high speed position, four−wheel  
drive, center differential locked): Lever  
at “H”, “4WD” button pushed in center  
differential lock switch pushed in  
When the shifting has not been completed  
within 3 seconds after the shifting opera-  
tion, the indicator flashes. If the indicator  
light does not go off when you push out  
the center differential lock button, drive  
straight ahead while accelerating or decel-  
erating, or drive in reverse. If the indicator  
flashes even if doing so, contact your  
Toyota dealer as soon as possible. There  
may be a trouble in the center differential  
lock system.  
Use this for greater traction when you  
experience  
a
loss of power, such as  
wheel slipping, in the center differential  
unlock mode.  
See “(c) Shifting procedure” for further in-  
structions.

(b) A.D.D. (automatic  
disconnecting differential)  
Advice for driving on slippery roads in  
“L4” (low speed position) mode  
(As for the automatic transmission lever  
positions, see “Automatic transmission” in  
this section.)  
The A.D.D. can be engaged or disen-  
gaged by the shifting operations des-  
cribed in “(c) Shifting procedure”.  
If you shift the front drive control lever to  
“L4” and the automatic transmission lever  
to “2” when you drive in steep off−road  
areas, the output of the brake can be  
controlled effectively by the active traction  
control system, which assists the driver to  
control the driving power of 4 wheels.  
You should drive in four−wheel drive for  
at least 16 km (10 miles) each month.  
This will assure that the front drive com-  
ponents are lubricated.  
Use the “L” position of the automatic  
transmission lever for maximum power  
and traction when your wheels get stuck  
or when you drive down a steep incline.  
In the following cases, the output of the  
brake can be controlled by the active trac-  
tion control system if the engine speed is  
under 3000 rpm (normally engine speed is  
under 3000 rpm when the wheels get un-  
stuck).  
D The front drive control lever in the “L4”  
position and the automatic transmission  
lever in the “L” position or the automat-  
ic transmission lever in the “D” or “2”  
with the transmission downshifting to  
the first gear  
D The front drive control lever in the “L4”  
position and the automatic transmission  
lever in the “R” position

SHIFTING BETWEEN “H” (2WD) MODE  
AND “H” (4WD) MODE  
SHIFTING  
UNLOCKED) AND “H” (4WD LOCKED)  
BETWEEN  
“H”  
(4WD,  
To shift from “H” (4WD LOCKED) to  
“H” (4WD UNLOCKED), left out the cen-  
ter differential lock switch.  
To shift from “H” (2WD) mode to “H”  
(4WD) mode, reduce your speed to less  
than 100 km/h (62 mph) and push in the  
“4WD” button.  
To shift from “H” (4WD, UNLOCKED) to  
“H” (4WD, LOCKED), push in the center  
differential lock switch.  
This can be done at any vehicle speed.  
If the indicator light flashes when you left  
out the center differential lock switch,  
drive straight ahead while accelerating or  
decelerating, or drive in reverse.  
If the indicator light flashes when you  
push in the center differential lock switch,  
drive straight ahead while accelerating or  
decelerating.  
If the indicator light flashes when you  
push in the “4WD” button, drive straight  
ahead while accelerating or decelerating.  
SHIFTING BETWEEN “H” AND “L4”  
If the indicator light flashes and the buzz-  
er sounds when you push in the “4WD”  
button, reduce your speed or stop the  
vehicle and reset.  
If the indicator light flashes and the buzz-  
er sounds when you push in the center  
differential lock switch, reduce your speed  
or stop the vehicle and reset.  
Stop the vehicle and put the transmission  
in “N”. With your foot holding down the  
brake pedal, move the front drive control  
lever.  
If the indicator light flashes when you  
move the front drive control lever, drive  
straight ahead while accelerating or decel-  
erating.  
CAUTION  
CAUTION  
Never push the “4WD” button if  
wheels are slipping. Stop the slipping  
or spinning before shifting.  
Never push the center differential  
lock button if wheels are slipping.  
Stop the slipping or spinning before  
shifting.  
CAUTION  
To shift from “H” (4WD) mode to “H”  
(2WD) mode, push the “4WD” button  
again to turn it off.  
Never move the front drive control  
lever if wheels are slipping. Stop the  
slipping or spinning before shifting.  
NOTICE  
Do not drive on a dry paved surface  
in “H” (4WD, LOCKED) mode. This  
may damage the locking mechanism  
and the drive system.  
This can be done at any vehicle speed.  
If the indicator light flashes when you  
push in the “4WD” button, drive straight  
ahead while accelerating or decelerating,  
or drive in reverse.
