Exhaust gas precautions
Harmful substance to the human body is included in exhaust
gases if inhaled.
WARNING
Exhaust gases include harmful carbon monoxide (CO), which is colorless and
odorless. Observe the following precautions.
Failure to do so may cause exhaust gases enter the vehicle and may lead to
an accident caused by light-headedness, or may lead to death or a serious
health hazard.
■Important points while driving
●Keep the back door and glass hatch closed.
● If you smell exhaust gases in the vehicle even when the back door and
glass hatch are closed, open the windows and have the vehicle inspected
at your Toyota dealer as soon as possible.
■ When parking
●If the vehicle is in a poorly ventilated area or a closed area, such as a
garage, stop the engine.
● Do not leave the vehicle with the engine on for a long time.
If such a situation cannot be avoided, park the vehicle in an open space
and ensure that exhaust fumes do not enter the vehicle interior.
● 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.
■ Exhaust pipe
The exhaust system needs to be checked periodically. 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.

WARNING
Observe the following precautions.
Failure to do so may result in death or serious injury.
■When driving the vehicle
●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. 234)
● Do not adjust the positions 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.
● Always check that all passengers’ arms, heads or other parts of their body
are not outside the vehicle.
● 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 y our 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.
● Sudden acceleration, engine braking due to shifting, or changes in engine
speed could cause the vehicle to skid.
● 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.

NOTICE
■To prevent battery discharge
●Do not leave the engine switch in ACCESSORY or IGNITION ON mode
for long periods of time without the engine running.
● If “ACCESSORY” or “IGNITION ON” is displayed on the multi-information
display while the engine is not running, the engine switch is not off. Exit the
vehicle after turning the engine switch off.
● Do not stop the engine when the shift lever is in a position other than P. If
the engine is stopped in another shift lever position, the engine switch will
not be turned off but instead be turned to ACCESSORY mode. If the vehi-
cle is left in ACCESSORY mode, battery discharge may occur.
■ When starting the engine
●Do not race a cold engine.
● If the engine becomes difficult to star t or stalls frequently, have your vehi-
cle checked by your Toyota dealer immediately.
■ Symptoms indicating a malfunction with the engine switch
If the engine switch seems to be operating somewhat differently than usual,
such as the switch sticking slightly, there may be a malfunction. Contact
your Toyota dealer immediately.
