CAUTION
Do not use the rear differential lock
in the conditions other than above.
Large steering effort and careful cor-
nering control will be required.
Lock
Unlock
To lock the rear differential, push the
switch.
Be sure to stop the wheels before locking
the differential.
For easy locking, depress the clutch ped-
al, push the lock switch and slowly re-
lease the clutch pedal.
The indicator light will blink when the
switch is turned on. Wait a few seconds
for the system to complete operation. Af-
ter the differential is locked, the light will
stop blinking and remain on.
The anti-lock brake system does not oper-
ate when the rear differential is locked. It
is normal operation for the ºABSº warning
light to be on at this time.
CAUTION
Do not lock the differential until the
wheels have stopped spinning.
Otherwise, the vehicle may move in
an unexpected direction when the
differential lock is engaged, result-
ing in an accident. This may also
lead to possible damage to differen-
tial lock component parts.
Do not drive over 8 km/h (5 mph)
when the differential is locked.
To unlock the differential, push the
switch once again.
Unlock the differential as soon as the ve-
hicle moves out.
For easy unlocking, slightly turn the steer-
ing wheel in either direction while the ve-
hicle is in motion.
When the differential lock is disengaged,
the indicator light will go out.
Except for Pre Runner models '
The differential will also unlock if you shift
the front drive control lever out of ºL4º.
Never forget to turn off the switch after
using this feature.

Brake system
TANDEM MASTER CYLINDER BRAKE SYSTEM
The tandem master cylinder brake system
is a hydraulic system with two separate
sub-systems. If either sub-system s
hould
fail, the other will still work. However, the
pedal will be harder to press, and your
stopping distance will be longer. Also, the
brake system warning light may come on.
CAUTION
Do not drive your vehicle with only a
single brake system. Have your
brakes fixed immediately.
BRAKE BOOSTER
The brake booster uses engine vacuum to
power-assist the brakes. If the engine
should quit while you are driving, you can
bring the vehicle to a stop with normal
pedal pressure. There is enough reserve
vacuum for one or two stops±but no more!
CAUTION
Do not pump the brake pedal if the
engine stalls. Each push on the
pedal uses up your vacuum reserve.
Even if the power assist is com-
pletely lost, the brakes will still
work. But you will have to push the
pedal hardÐmuch harder than nor-
mal. And your braking distance will
be longer.
ANTI-LOCK BRAKE SYSTEM
(with ºABSº warning light)
The anti-lock brake system is designed to
automatically help prevent lock- up of the
wheels during sudden braking or braking
on slippery road surfaces. This assists in
providing directional stab ility and steering
performance of the vehicle under these
circumstances.
The anti-lock brake system becomes op-
erative after the vehicle has accelerated
to a speed in excess of approximately 10
km/h (6 mph). It stops operating when the
vehicle decelerates to a speed below
approximately 5 km/h (3 mph).
You may hear a sound in the engine
compartment for a few seconds when the
engine is started or just after the vehicle
is started. This means that the anti-lock
brake system is in the self check mode,
and does not indicate a malfunction.
Effective way to press the ºABSº brake
pedal: When the anti- lock brake system
function is in action, you may feel the
brake pedal pulsating and hear a noise.
In this situation, to let the anti- lock
brake system work for you, just hold the
brake pedal down more firmly. Do not
pump the brake. This will result in re-
duced braking performance.
The brake pedal pulsation caused by the
anti-lock brake system may indicate haz-
ardous road surface conditions. Although
the anti-lock brake system assists in pro-
viding vehicle control, it is still important
to drive with all due care, because the
anti-lock brake system cannot overcome
the laws of physics that act on your ve-
hicle: Braking capab ility is dependent on tire
friction with the road surface.
Even though the anti-lock brake system
is operating, a driver cannot maintain
full control on certain slippery road sur-
faces, when cornering at high speeds,
or in violent maneuvers.
Avoid high speeds on wet roads. The
anti-lock brake system cannot eliminate
the risk of hydroplaning and loss of tire
friction.
