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 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. (→ P. 554)
■ Vo l t m e t e r
When the voltmeter indicates 19 V or higher or 9 V or lower while the engine
is running, there may be a battery or charging system malfunction. Have the
vehicle inspected at your Toyota dealer.
■ Engine oil pressure gauge
When the value of the engine oil pressure gauge drops while the engine is
running, stop the vehicle in a safe place immediately and check the amount
of engine oil. ( →P. 460)
When the oil pressure drops even though the engine oil amount has not
decreased, or if the oil pressure does not increase when engine oil is
added, contact your Toyota dealer, as there may be a problem with the lubri-
cation system.

4-1. Before driving
WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When the vehicle is parked
● Always apply the parking brake, shift the shift lever to P, stop the engine
and lock the vehicle.
Do not leave the vehicle unattended while the engine is running.
If the vehicle is parked with the shift lever in P but the parking brake is not
set, the vehicle may start to move, possibly leading to an accident.
● If the shift lever is moved before the low speed four-wheel drive indicator
turns on/off, the transfer mode may not be shifted completely. The transfer
mode disengages both the front and rear driveshafts from the powertrain
and allows the vehicle to move regardless of the shift position. (At this
time, the indicator blinks and the buzzer sounds.)
Therefore, the vehicle is free to roll even if the automatic transmission is in
P. You or someone else could be seriously injured. You must complete the
shifting of the transfer mode. ( →P. 286)
● Do not touch the exhaust pipes while the engine is running or immediately
after turning the engine off.
Doing so may cause burns.
■ When taking a nap in the vehicle
Always turn the engine off. Otherwise, if you accidentally move the shift
lever or depress the accelerator pedal, this 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, leading to
death or a serious health hazard.
■ When braking
● When the brakes are wet, drive more cautiously.
Braking distance increases when the brakes are wet, and this 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 hills or sharp turns that require braking. In this
case, braking is still possible, but the brake pedal should be depressed
more firmly than usual. Also, the braking distance will increase. Have your
brakes fixed immediately.
● 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 the braking distance will\
increase.
Have your brakes fixed immediately.

4-1. Before driving
●Avoid jerky starts or sudden acceleration.
● Avoid jerky steering and sharp turns, and slow down before making
a turn.
● Note that when making a turn, the 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 crosswinds, on wet or slippery
surfaces, etc.
Increasing vehicle speed c an destabilize the trailer.
● Take care when passing other vehicles. 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.
● To maintain engine braking efficiency and charging system perfor-
mance when using engine braking, do not put the transmission in
D.
If in the S mode, the transmission shift range position must be in 6
or lower. ( →P. 205)
● 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 over-
heat on hot days (at temperatures over 85°F [30°C]) when driving
up a long or steep grade. If t he engine coolant temperature gauge
indicates overheating, immediately turn off the air conditioning (if in
use), pull your vehicle off the road and stop in a safe spot.

4-2. Driving procedures
■Steering lock
After turning the engine switch off and opening and closing the doors, the
steering wheel will be locked due to the steering lock function. Operating the
engine switch again automatically cancels the steering lock.
■ When the steering lock cannot be released
■ Steering lock motor o verheating prevention
To prevent the steering lock motor from overheating, the motor may be sus-
pended if the engine is turned on and off repeatedly in a short period of time.
In this case, refrain from running the engine. After about 10 seconds, the
steering lock motor will resume functioning.
■ When “Smart Key Syst em Malfunction See Owner’s Manual” is dis-
played on the multi-information display
The system may be malfunctioning. Have the vehicle inspected by your
Toyota dealer, immediately.
