CAUTION

Always keep your foot on the brake pedal while stopped with the engine running. This prevents the vehicle from creeping.

NOTICE

Always use the brake pedal or the parking brake to hold the vehicle on an upgrade. Do not attempt to hold the vehicle using the accelerator ped- al, as this can cause the transmission to overheat.

Use the four−wheel drive control switch knob and center differential lock switch to select the transfer and center differ- ential modes. The “H4” and “L4” positions of the four− wheel drive control switch knob provide either lock or unlock mode of the center differential depending on the center differ- ential lock switch position. 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 is locked, the vehicle stability control system is automatically turned off and the center differential lock and “VSC OFF” indicator lights come on because the function that controls engine performance interferes with the process of freeing your wheels.

If the “4LO” (low speed four−wheel drive) indicator light continues to blink when you operate control switch knob to the “H4” or “L4” position, drive forward or backward in a short dis- tance, then stop the vehicle completely, shift the automatic transmission selector lever securely into “N” and operate the switch knob again. If the indicator continues to blink even if doing so, contact your Toyota dealer as soon as possible. There may be a trouble in the four−wheel drive system.

CAUTION

Never operate the four−wheel drive control switch knob if the wheels are slipping. Stop the slipping or spin- ning before operating.

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, center differential un- locked) mode. Also, using this mode when driving down steep off−road inclines will help contribute to increased vehicle stabil- ity. The indicator light tells when the differen- tial lock is engaged. Note that the differ- ential is not still locked as long as the indicator light remains off. When the operation is not completed, the indicator blinks. If the indicator light does not go off when you push out the center differential switch, drive straight ahead while accelerating or decelerating, or drive in reverse. If the center differential lock system op- eration is not completed within 5 seconds while is set, cancel the cruise control system. To can- cel the cruise control system, see “Cruise control” on page 195 in Section 1−7. If the indicator blinks even if doing so, contact your Toyota dealer as soon as possible.

Downhill assist control system (four−wheel drive models) The downhill assist control system is a system that assists the deceleration of the engine brake when you drive down a steep hill. When you are driving down a hill with the four−wheel drive control switch knob (full−time four−wheel drive models) or multi−mode control switch knob four−wheel drive models) in the “L4” position, push the “DAC” switch to limit the vehicle’s ac- celeration. If the vehicle is traveling at a speed of 25 km/h (15 mph) or less, you can descend at a constant speed.

CAUTION

Do not rely excessively on the down- hill assist control system. It may not be able to maintain a low speed over road surfaces or off−road surfaces on which sliding can easily occur, such as extremely steep slopes or icy or muddy roads.

With the vehicle traveling at a speed of 25 km/h (15 mph) or less, release your foot from the accelerator or brake pedal to activate the system. The vehicle will descend the hill at a low speed. While the system is operating, the slip indicator light on the instrument panel will flash and the stop lights and high mounted stoplight will be lit. If you push the “DAC” switch to turn the system off while it is in operation, the system will stop operating gradually. The downhill assist control system indicator light will flash to alert the driver. To con- tinue driving at a low speed, push the “DAC” switch to turn the system on.

Hill−start assist control system The hill−start assist control system as- sists you in starting to move up a steep or slippery hill.

LOW TIRE PRESSURE WARNING LIGHT This light comes on when the ignition key is turned to the “ON” position. It goes off after a few seconds. This indicates that the tire pressure warning system is func- tioning properly. If the low tire pressure warning light comes on or blinks, do the following. If the warning light comes on: Stop your vehicle in a safe place as soon as possible and check that the inflation pressure of all tires (including the spare tire) is as specified on the tire and loading information label. (See “Checking inflation pressure” on page 425 in Section 7−2.) If the warning light comes on even after tire inflation pressure adjustment, you may have a flat tire. If you have a flat tire, replace it with the spare tire. For details, see “If you have a flat tire” on page 379 in Section 4. The warning light goes off a few minutes after air is put into the deflated tire. This warning light may turn on due to natural causes such as natural air leaks or tire pressure changes caused by tem- perature. In this case, adjusting the tire pressure will turn off the warning light.

CAUTION

D The use of non−genuine wheels will cause the air pressure sensors to transmit the electronic code in dif- ferent manner, resulting in the sys- tem failure.

D The use of different type of tires with genuine wheels may also cause the malfunction of the sys- tem.

CAUTION

Each tire, including the spare (if pro- vided), should be checked monthly when cold and inflated to the inflation pressure recommended by the vehicle manufacturer on the vehicle placard or tire inflation pressure label (tire and load information label). (If your vehicle has tires of a different size than the size indicated on the vehicle placard or tire inflation pressure label (tire and load information label), you should determine the proper tire infla- tion pressure for those tires.)

If the warning light blinks: The tire pressure warning system may be malfunctioning. Contact your Toyota dealer. SYSTEM MALFUNCTION The tire pressure warning system does not function properly under certain cir- cumstances. In the following cases, the low tire pressure warning light may not come on even if the tire inflation pres- sure is low, or it may come on when the tire is actually normal.
