Four-wheel drive system (if equipped)
Use the front wheel drive control switch to select the following trans-
fer modes.
*1: Vehicles with multi-information display
*2: Vehicles without multi-information display
2WD (high speed position, two-wheel drive)
Normal driving.
4H (high speed position, four-wheel drive)
Greater traction than two wheel drive.
When you experience a loss of power, such as wheel slipping.
The 4HI indicator comes on.
4L (low speed position, four-wheel drive)
Driving requiring maximum power and traction such as climbing or
descending steep hills, off-road driving and hard pulling in sand or mud,
etc.
The 4LO indicator comes on.
*2*1

210 2-4. Using other driving systems
■Shifting between 2WD and 4H
●Reduce your speed to less than 62 mph (100 km/h) and set the front
drive control switch between 2WD and 4H.
When the ambient temperature is 5.0° F (-15°C) or lower, shifting from
2WD to 4H can be performed with the vehicle speed below 43 mph (70
km/h).
● If the 4HI indicator does not go off when you shift from 4H to 2WD, drive
straight ahead while accelerating or decelerating, or drive in reverse.
■ Four-wheel drive usage frequency
You should drive in four-wheel drive for at least 10 miles (16 km) each
month.
This will assure that the front drive components are lubricated.
■ The center differential lock switch can be operated when
●The front drive control switch is in the 4H or 4L position.
● The vehicle speed is less than 62 mph (100 km/h)
■ Center differential lock system
●When the center differential is locked, the vehicle stability control system
is automatically turned off and the center differential lock and VSC OFF
indicator come on.
● When the front drive control switch is turned to the 2WD position, the
center differential is automatically unlocked.
● If the operation is not completed, the center differential lock indicator
blinks. If the indicator does not go off when unlocking the center differen-
tial, drive straight ahead while accelerating or decelerating, or drive \
in
reverse.
■ If the 4LO indicator, 4HI indicator or the center differential lock indica-
tor blinks
● If the 4LO indicator continues to blink when shifting between 4H and 4L,
stop the vehicle completely, move the shift lever to N and operate the
switch again.
● If the shift lever is moved before the 4LO indicator has turned on/off, a
beep sounds and the transfer position may not successfully change. In
this case, stop the vehicle completely, return the shift lever to N and oper-
ate the switch again.

When driving
●If the engine coolant temperature is too low, transfer mode may not be
able to shift. When the engine is warmer turn the switch again.
If the 4LO indicator, 4HI indicator or the center differential lock indicator con-
tinues to blink even after attempting the above, there may be a malfunction
in the engine, the brake system or the four-wheel drive system. In this case,
you may not be able to shift between 2WD and 4H, 4H and 4L, and the cen-
ter differential lock may not be operable. Have the vehicle inspected by your
Toyota dealer immediately.
CAUTION
■ Shift from 2WD to 4H while driving
Never move the front wheel drive control switch if wheels are slipping.
Stop the slipping or spinning before shifting.
NOTICE
■To prevent damage to the center differential
●For normal driving on dry and hard surface roads, unlock the center differ-
ential.
● Unlock the center differential after the wheels are out of the ditch or off the
loose or bumpy surface.
● Do not push the center differential lock switch when the vehicle is corner-
ing or when its wheels are spinning freely off the ground.

Winter driving tips
Carry out the necessary preparations and inspections before driving
the vehicle in winter. Always drive the vehicle in a manner appropri-
ate to the prevailing weather conditions.
■ Pre-winter preparations
●Use fluids that are appropriate to the prevailing outside tem-
peratures.
• Engine oil
• Engine coolant
• Washer fluid
● Have a service technician inspect the level and specific grav-
ity of battery electrolyte.
● Have the vehicle fitted with four snow tires or purchase a set
of tire chains for the rear tires.
Ensure that all tires are the same size and brand, and that chains
match the size of the tires.
■Before driving the vehicle
Perform the following according to the driving conditions.
●Do not try to forcibly open a window, scrape an outside rear
view mirror surface or move a wiper or outside rear view mir-
ror that is frozen. Pour warm water over the frozen area to
melt the ice. Wipe away the water immediately to prevent it
from freezing.
● To ensure proper operation of th e climate control system fan,
remove any snow that has accumulated on the air inlet vents
in front of the windshield.
● Remove any ice that has accumu lated on the vehicle chassis.
● Periodically check for and remove any excess ice or snow
that may have accumulated in the wheel well or on the
brakes.

Maintenance and care
■Replacing tires and wheels
If the ID code of the tire pressure warning valve and transmitter is not
registered, the tire pre
ssure warning system will not work properly. After
driving for about 20 minutes, the ti re pressure warning light comes on
after blinking for 1 minute to indicate a system malfunction.
■Tire life
Any tire over 6 years old must be checked by a qualified technician even
if they have seldom or never been used or damage is not obvious.
■If the tread wears down below 0.16 in. (4 mm) on snow tires
The effectiveness of snow tires is lost.
■Low profile tires
Generally, low profile tires will wear more rapidly and tire grip perfor-
mance will be reduced on snowy and/or icy roads when compared to
standard tires. Be sure to use snow tires or snow chains on snowy and/
or icy roads and drive carefully at a speed appropriate for road and
weather conditions.
■Maximum load of tire
Check that the maximum load of the re placed tire is greater than 1/2 of
the Gross Axle Weight Ratings (GAWR) of either the front axle or the
rear axle, whichever is greater.
As for the maximum load of the tire, see the load limit at maximum cold
tire inflation pressure mentioned on the sidewall of the tire, and as for the
Gross Axle Weight Ratings (GAWR) , see the Certification Label.
(  P. 461, 558).
■Tire types
1 Summer tires
Summer tires are high-speed performance tires best suited to highway
driving under dry conditions. Since summer tires do not have the same
traction performance as snow tire s, summer tires are inadequate for
driving on snow-covered or icy roads. For driving on snow-covered
roads or icy roads, the use of snow tires is recommended. When
installing snow tires, be sure to replace all four tires.
