138 2-1. Driving procedures
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. 147150)
● 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.

When driving
CAUTION
■
When driving on slippery road surfaces
●After driving through a puddle, lightly depress the brake pedal to make
sure that the brakes are functioning properly. Wet brake pads may prevent
the brakes from functioning properly. If the brakes on only one side are wet
and not functioning properly, steering control may be affected, resulting in
an accident.
■ When shifting the shift lever
Vehicles with an automatic transmission, be careful not to shift the shift lever
with the accelerator pedal depressed.
This may lead to unexpected rapid acceleration of the vehicle that may
cause an accident and result in death or serious injury.
■ When the vehicle is stopped
●Do not race the engine.
If the vehicle is in any gear other than P (automatic transmission only) or
N, the vehicle may accelerate suddenly and unexpectedly, and may cause
an accident.
● Do not leave the vehicle with the engine running for a long time.
If such a situation cannot be avoided, park the vehicle in an open space
and check that exhaust fumes do not enter the vehicle interior.
● Vehicles with an automatic transmission, in order to prevent accidents due
to the vehicle rolling away, always keep depressing the brake pedal while
the engine is running, and apply the parking brake as necessary.
● If the vehicle is stopped on an incline, in order to prevent accidents caused
by the vehicle rolling forward or ba ckward, always depress the brake pedal
and securely apply the parking brake as needed.
● Avoid revving or racing the engine.
Running the engine at high speed while the vehicle is stopped may cause
the exhaust system to overheat, which could result in a fire if combustible
material is nearby.

When driving
CAUTION
■
Exhaust gases
●Toyota does not recommend occupying the rear cargo area when it is fitted
with a slide-in camper, camper shell or other type cover while the engine is
running. This caution applies to both driving and stopped or parked situa-
tions with the engine running. Particular care should be taken to prevent
exhaust gases from entering camper bodies, trailers or other enclosures
on or around your vehicle. If exhaust fumes are detected, open all win-
dows and thoroughly ventilate the area.
■ 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.
● If the power brake assist function does not operate, do not follow other
vehicles closely and avoid downhills or sharp turns that require braking.
In this case, braking is still possible, but it will require more force on the
pedal than usual. Braking distance may also increase.
● Do not pump the brake pedal if the engine stalls.
Each push on the brake pedal uses up the reserve for the power-assisted
brakes.
● The brake system consists of 2 individual hydraulic systems: If one of the
systems fails, the other will still operate. In this case, the brake pedal
should be depressed more firmly than usual and braking distance
becomes longer.
Do not drive your vehicle with only a single brake system. Have your
brakes fixed immediately.

146 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.

When driving
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 engine coolant 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. (

2-4. Using other
driving systems
2
When driving
■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 3 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, a buz zer will sound and A-TRAC indicator
blink to alert the driver. Stop the vehicle in a safe place. (There is no problem
with continuing normal driving.)
The system will be automatically restored after a short time.
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.

190 2-4. Using other driving systems
■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 front-wheel drive control switch is in the H2 or H4 position.
● The rear differential is locked.
■ The downhill assist control system indicator light flashes when
● The shift lever is in the N position.
● The front-wheel drive control switch is in the H2 or H4 position.
● The rear differential is locked.
■ 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. (There is no problem with continuing normal
driving.)
■ System malfunction
●The downhill assist control system indicator does not come on when the
engine switch is turned to the ON position.
● The downhill assist control system 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.

When driving
●
Avoid jerky starts or sudden acceleration.
● Avoid jerky steering and sharp turns, and slow down before mak-
ing a turn.
● Note that when making a turn, th e trailer wheels will be closer than
the vehicle wheels to the inside of the turn. Compensate by making
a wider than normal turning radius.
● Slow down before making a turn, in cross winds, on wet or slippery
surfaces, etc.
Increasing vehicle speed can destabilize the trailer.
● Take care when passing other vehicles. Passing requires consider-
able distance. After passing a vehicle, do not forget the length of
your trailer, and be sure you hav e plenty of room before changing
lanes.
● To maintain engine braking efficiency and charging system perfor-
mance when using engine braking, do not use fifth gear (5-speed
manual transmission), sixth gear (6-speed manual transmission),
or do not put the transmission in D (automatic transmission).
● Instability happens more frequently when descending steep or long
downhill grades. Before descending, slow down and downshift. Do
not make sudden downshifts while descending steep or long down-
hill grades.
● Avoid holding the brake pedal down too long or applying the
brakes too frequently. This could cause the brakes to overheat and
result in reduced braking efficiency.
● Due to the added load of the trailer, your vehicle’s engine may
overheat on hot days (at temperatures over 85°F [30°C]) when
driving up a long or steep grade. If the engine coolant temperature
gauge indicates overheating, immedi ately turn off the air condition-
ing (if in use), pull your vehicle off the road and stop in a safe spot.
