Use the front drive control lever to se-
lect the following transfer modes.
ªH2º (high speed position, two±wheel
drive): Lever at ªH2º

surfaced roads. This position gives greater
economy, the quietest ride and least wear.
ªH4º (high speed position, four±wheel
drive): Lever at ªH4º
Use this for normal driving on wet, icy or
snow±covered roads. This position pro-
vides greater traction than two±wheel
drive. ªNº (neutral position):
Lever at ªNº
No power is delivered to the wheels. The
vehicle must be stopped.
ªL4º (low speed position, four±wheel
drive): Lever at ªL4º

drive straight ahead while accelerating or
decelerating, or drive forward or backward
in a short distance. You need not depress
the clutch pedal.
If you have trouble shifting in cold weath-
er, reduce the vehicle speed or stop the
vehicle and reshift.
CAUTION

NOTICE
Do not crank for more than 30 se-
conds at a time. This may overheatthe starter and wiring systems.
Do not race a cold engine.
If the engine becomes difficult tostart or stalls frequently, have the
engine checked immediately.

Always slow down in gusty crosswinds.
This will allow you much better control.

Drive slowly onto curbs and, if pos-
sible, at a right angle. Avoid driving
onto high, sharp±edged objects and
other road hazards. Failure to do so
can lead to severe tire damage result-
ing in tire bursts.

When parking on a hill, turn the front
wheels until they touch the curb so
that the vehicle will not roll. Apply the
parking brake, and place the transmis-
sion in ªPº (automatic) or in first or
reverse (manual). If necessary, block
the wheels.

Washing your vehicle or driving through
deep water may get the brakes wet. To
see whether they are wet, check that
there is no traffic near you, and then
press the pedal lightly. If you do not
feel a normal braking force, the brakes
are probably wet. To dry them, drive
the vehicle cautiously while lightly
pressing the brake pedal with the park-
ing brake applied. If they still do not
work safely, pull to the side of the road
and call a Toyota dealer for assistance.

Four±wheel drive modelsÐToyota rec-
ommends not using four±wheel drive on
dry hard±surfaced roads, because four±
wheel driving will cause unnecessary
noise and wear, and poor fuel econo-
my.

Four±wheel drive modelsÐIn cold tem-
peratures, noise may occur when driv-
ing in two±wheel drive before the trans-
fer is warmed up. Therefore, first drive
in four±wheel drive until the transfer is
warmed up.
