106 2-1. Driving procedures
CAUTION
nWhen driving the vehicle
lDo not under any circumstances shift the shift lever to P, R or N (automatic
transmission) or R (manual transmission) while the vehicle is moving.
Doing so can cause significant damage to the transmission system and
may result in a loss of vehicle control.
l 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.
l 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.
l 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. 116,118)
l 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.
l 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.
l 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.
l 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.
n When driving on slippery road surfaces
lSudden braking, acceleration and steering may cause tire slippage and
reduce your ability to control the vehicle, resulting in an accident.

When driving
CAUTION
n
When driving on slippery road surfaces
lSudden 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.
l 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.
n 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.
n When the vehicle is stopped
lDo 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.
l 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.
l 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.
l 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.
l 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
n
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.
n When braking the vehicle
lWhen 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.
l 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.
l 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.
l 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.

NOTICE
n
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.
n When starting the engine
lDo not crank for more than 30 seconds at a time. This may overheat the
starter and wiring systems.
l Do not race a cold engine.
l If the engine becomes difficult to start or stalls frequently, have the engine
checked immediately.

Darker
With the dial turned fully up, the
intensity of the instrument panel
lights will not be reduced even
when the tail lights/headlights are
turned on.
NOTICE
nTo prevent damage to the engine and its components
lDo not let the indicator needle of the tachometer enter the red zone, which
indicates the maximum engine speed.
l The engine may be overheating if the high engine coolant temperature
warning light comes on. In this case, immediately stop the vehicle in a safe
place, and check the engine after it has cooled completely. (
→P. 329)

When driving
nVSC OFF mode
Stop the vehicle completely, and
press the VSC OFF switch for
more than 3 seconds.
The TRAC OFF and VSC OFF
indicators will come on.
The system is in TRAC off and
VSC off mode.
nSounds and vibrations caused by the ABS, TRAC, VSC and brake
assist system
lA 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
l 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.
n 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.)

144 2-4. Using other driving systems
nAutomatic reactivation of TRAC and VSC
Turning the engine switch OFF after turning off the TRAC and VSC systems
will automatically re-enable them.
n Automatic TRAC reactivation
If only the TRAC system is turned off, the TRAC system will turn on when
vehicle speed increases.
n Automatic TRAC and VSC reactivation
If the TRAC and VSC systems are turned off, the systems will not turn on
even when vehicle speed increases.
n If the slip indicator light up
There is a malfunction in the TRAC and VSC systems. Contact your Toyota
dealer and have your Toyota inspected.
n EPS operation sound
When the steering wheel operates, a motor sound (whirring sound) may be
heard.
This does not indicate a malfunction.
n Reduced effectiveness of EPS
The effectiveness of EPS is reduced to prevent the system from overheating
when there is frequent steering input over an extended period of time. The
steering wheel may feel heavy as a result. Should this occur, refrain from
excessive steering input or stop the vehicle and turn the engine off. The sys-
tem should return to normal within 10 minutes.

160 2-5. Driving information
lTake care when passing other v ehicles. Passing requires consider-
able distance. After passing a vehi cle, do not forget the length of
your trailer, and be sure you hav e plenty of room before changing
lanes.
l In order to maintain engine braking efficiency, do not use the trans-
mission in D (automatic transmission) or 5 (manual transmission).
l Due to the added load of the trailer, your vehicle’s engine may
overheat on hot days (at temper atures over 85°F [30°C]) when
driving up a long or steep grade. If the engine coolant temperature
gauge indicates overheating, immediately turn off the air condition-
ing (if in use), pull your vehicle off the road and stop in a safe spot.
( → P. 329)
l Always place wheel blocks under both the vehicle and the trailer
wheels when parking. Apply the parking brake firmly, and put the
transmission in P (automatic transmission) or in 1 or R (manual
transmission). Avoid parking on a slope, but if unavoidable, do so
only after performing the following:
Apply the brakes and keep them applied.
Have someone place wheel bloc ks under both the vehicle and
trailer wheels.
When the wheel blocks are in place, release the brakes slowly
until the blocks absorb the load.
Apply the parking brake firmly.
Shift into 1 or R (manual transmission) or P (automatic trans-
mission) and turn off the engine.

When driving
l
When restarting after parking on a slope:
With the transmission in P (automatic transmission) or the
clutch pedal (manual transmission) depressed, start the
engine. On vehicles with an au tomatic transmission, be sure
to keep the brake pedal pressed.
Shift into a forward gear. If reversing, shift into R.
Release the parking brake (also brake pedal on vehicles with
an automatic transmission), and slowly pull or back away from
the wheel blocks. Stop and apply the brakes.
Have someone retrieve the blocks.
CAUTION
n To avoid an accident
lDo not exceed 45 mph (72 km/h) or posted towing speed limit, whichever
is lower. As instability (swaying) of the towing vehicle-trailer combination
increases as speed increases, exceeding 45 mph (72 km/h) may cause
loss of control.
l Slow down and downshift before descending steep or long downhill
grades. Do not make sudden downshifts.
l Avoid holding the brake pedal down too long or too frequently. This could
cause the brakes to overheat and result in reduced braking efficiency.
