2-1. Driving procedures

When driving
CAUTION
■
When driving the vehicle
●Do not shift the shift lever to N while the vehicle is moving.
Doing so may cause the engine brake to not operate properly and lead to
an accident.
● Do not turn the engine off while driving.
The power steering and brake booster systems will not operate properly if
the engine is not running.
● Use engine braking (downshift) to maintain a safe speed when driving
down a steep hill.
Using the brakes continuously may cause the brakes to overheat and lose
effectiveness. ( P. 144)
● When stopped on an inclined surface, use the brake pedal and parking
brake to prevent the vehicle from rolling backward or forward and causing
an accident.
● Do not adjust the position of the steering wheel, the seat, or the inside or
outside rear view mirrors while driving.
Doing so may result in a loss of vehicle control that can cause accidents
that may result in death or serious injury.
● Always check that all passengers’ arms, heads or other parts of their bod-
ies are not outside the vehicle, as this may result in death or serious injury.
● Do not drive in excess of the speed limit. Even if the legal speed limit per-
mits it, do not drive over 85 mph (140 km/h) unless your vehicle has high-
speed capability tires. Driving over 85 mph (140 km/h) may result in tire
failure, loss of control and possible injury. Be sure to consult a tire dealer
to determine whether the tires on your vehicle are high-speed capability
tires or not before driving at such speeds.
■ When driving on slippery road surfaces
●Sudden braking, acceleration and steering may cause tire slippage and
reduce your ability to control the vehicle, resulting in an accident.
● Sudden changes in engine speed, such as engine braking caused by up-
shifting or down-shifting, may cause the vehicle to skid, resulting in an
accident.

2-1. Driving procedures

When driving
CAUTION
■
When the vehicle is parked
●Do not touch the exhaust pipe while the engine is running or immediately
after turning the engine off.
Doing so may cause burns.
● Do not leave the engine running in an area with snow build-up, or where it
is snowing. If snowbanks build up around the vehicle while the engine is
running, exhaust gases may collect and enter the vehicle. This may lead
to death or a serious health hazard.
■ Exhaust gases
Exhaust gases include harmful carbon monoxide (CO) that is colorless and
odorless. Inhaling exhaust gases may lead to death or a serious health haz-
ard.
●If the vehicle is in a poorly ventilated area, stop the engine. In a closed
area, such as a garage, exhaust gases may collect and enter the vehicle.
This may lead to death or a serious health hazard.
● The exhaust should be checked occasionally. If there is a hole or crack
caused by corrosion, damage to a joint or abnormal exhaust noise, be
sure to have the vehicle inspected and repaired by your Toyota dealer.
Failure to do so may allow exhaust gases to enter the vehicle, resulting in
death or a serious health hazard.
■ When taking a nap in the vehicle
Always turn the engine off. Otherwise, you may accidentally move the shift
lever or depress the accelerator pedal, which could cause an accident or fire
due to engine overheating. Additionally, if the vehicle is parked in a poorly
ventilated area, exhaust gases may collect and enter the vehicle, leadin\
g to
death or a serious health hazard.
■ When braking the vehicle
●When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and may cause one
side of the vehicle to brake differently than the other side. Also the parking
brake may not securely hold the vehicle.

142 2-1. Driving procedures
CAUTION
■Caution while driving
Do not turn the engine switch to the LOCK position.
If in an emergency, you must turn the engine off while the vehicle is moving,
turn the engine switch only to the ACC position.
NOTICE
■To prevent battery discharge
Do not leave the engine switch in the ACC or ON position for long periods if
the engine is not running.
■ When starting the engine
●Do not crank for more than 30 seconds at a time. This may overheat the
starter and wiring systems.
● Do not race a cold engine.
● If the engine becomes difficult to start or stalls frequently, have the engine
checked immediately.

150 2-2. Instrument cluster
NOTICE
■To prevent damage to the engine and its components
●Do not let the indicator needle of the tachometer enter the red zone, which
indicates the maximum engine speed.
● The engine may be overheating if the temperature gauge is in the red
zone (H). In this case, immediately stop the vehicle in a safe place, and
check the engine after it has cooled completely. (
P. 463)

2-4. Using other
driving systems

When driving
When the active traction control system is operating
If all wheels spin, the slip indica-
tor flashes to indicate that the
active traction control system
have been engaged.
■When the rear differential is locked (vehicles with the rear differential
lock system)
The active traction control system is activated only when the vehicle speed
is less than 4 mph (6 km/h).
■ Sounds and vibrations caused by the active traction control system
●A sound may be heard from the engine compartment when the engine is
started or just after the vehicle begins to move. This sound does not indi-
cate that a malfunction has occurred in the system.
● Vibrations may be felt through the vehicle body and steering. It may
occur when the system is operating.
■ If the brake system overheats
The system will cease operation and a buzzer will sound to alert the driver.
Stop the vehicle in a safe place. (Ther e is no problem with continuing normal
driving.)
CAUTION
■ The active traction control system m ay not operate effectively when
Directional control and power may not be achievable while driving on slip-
pery road surfaces, even if the active traction control system is operating.
Do not drive the vehicle in conditions where stability and power may be lost.

2-4. Using other
driving systems
2
When driving
■Operating tips
The system will operate when the shift lever is in a position other than P.
However, to make effective use of the system it is recommended that the
shift lever be shifted to 2 or L.
■ The system will not operate when
The four-wheel drive control switch is in the H2 or H4 position.
■ The downhill assist control indicator flashes when
●The shift lever is in N.
● The four-wheel drive control switch is in the H2 or H4 position.
■ If the brake system overheats
The system will cease operation and a buzzer will sound to alert the driver.
Stop the vehicle in a safe place. (Ther e is no problem with continuing normal
driving.)
■ System malfunction
●The downhill assist control indicator does not come on when the engine
switch is turned to the ON position.
● The downhill assist control indicator does not come on when the DAC
switch is pressed.
In the above cases have your vehicle checked by your Toyota dealer.
CAUTION
■Do not rely excessively on the downhill assist control system
It may not be able to maintain a low speed over road surfaces on which slid-
ing can easily occur, such as extremely steep slopes or icy or muddy roads.

196 2-4. Using other driving systems
■Sounds and vibrations caused by the ABS, TRAC, A-TRAC, VSC and
brake assist system
● A sound may be heard from the engine compartment when the engine is
started or just after the vehicle begins to move. This sound does not indi-
cate that a malfunction has occurred in any of these systems.
● Any of the following conditions may occur when the above systems are
operating. None of these indicates that a malfunction has occurred.
• Vibrations may be felt through the vehicle body and steering.
• A motor sound may be heard after the vehicle comes to a stop.
• The brake pedal may pulsate slightly after the ABS is activated.
• The brake pedal may move down slightly after the ABS is activated.
■ If the brake system overheats
TRAC will cease operation and a buzzer will sound to alert the driver. Stop
the vehicle in a safe place. (There is no problem with continuing normal driv-
ing.)
