the road will be slippery.
●Drive carefully when it starts to rain,
because the road surface will be
especially slippery.
●Refrain from high speeds when driv-
ing on an expressway in the rain,
because there may be a layer of water
between the tires and the road sur-
face, preventing the steering and
brakes from operating properly.

4-1. Before driving
WARNING
●Do not drive the vehicle over or stop the vehicle near flammable
materials. The exhaust system and exhaust gases can be extremely hot. These
hot parts may cause a fire if there is any flammable material nearby.
●During normal driving, do not turn off the engine. Turning the engine off while driving will not cause loss
of steering or braking control, but the power assist to these systems will be lost. This will make it more
difficult to steer and brake, so you should pull over and stop the vehi-cle as soon as it is safe to do so.
However, in the event of an emer- gency, such as if it becomes impos-sible to stop the vehicle in the
normal way: →P. 3 0 6
●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.139)
●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 the vehicle off-road.
This is not an AWD vehicle designed for off-road driving. Pro-ceed with all due caution if it
becomes unavoidable to drive off- road.
●Do not drive across a river or through other bodies of water.This may cause electric/electronic
components to short circuit, dam- age the engine or cause other seri-ous damage to the vehicle.
■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 brak-
ing due to shifting, or changes in engine speed could cause the vehi-cle to skid.
●After driving through a puddle, lightly depress the brake pedal to
make sure that the brakes are func- tioning properly. Wet brake pads may prevent the brakes from func-
tioning properly. If the brakes on only one side are wet and not func-tioning properly, steering control
may be affected.
■When shifting the shift lever
●Do not shift the shift lever to R while the vehicle is moving forward.Doing so can damage the transmis-
sion and may result in a loss of vehicle control.
●Do not shift the shift lever to a driv-ing position while the vehicle is moving backward.
Doing so can damage the transmis- sion and may result in a loss of vehicle control.
●Moving the shift lever to N while the vehicle is moving will disengage the
engine from the transmission. Engine braking is not available when N is selected.

Driving
WARNING
■If you hear a squealing or scrap- ing noise (brake pad wear indica-
tors)
Have the brake pads checked and replaced by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer as soon as possible.
Rotor damage may result if the pads are not replaced when needed.
Front brakes only: Moderate levels of brake pad and disc wear allow
enhanced front braking power. As a result, the discs may wear more quickly than conventional brake discs.
Therefore, when replacing the brake pads, Toyota recommends that you also have the thickness of the discs
measured. It is dangerous to drive the vehicle when the wear limits of the brake pads and/or those of the brake
discs are exceeded.
■When the vehicle is stopped
●Do not race the engine. If the vehicle is in any gear other than N, the vehicle may accelerate
suddenly and unexpectedly, caus- ing an accident.
●If the vehicle is stopped on an incline, in order to prevent acci-dents caused by the vehicle rolling
forward or backward, 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 over-
heat, which could result in a fire if combustible material is nearby.
■When the vehicle is parked
●Do not leave glasses, cigarette lighters, spray cans, or soft drink
cans in the vehicle when it is in the sun.Doing so may result in the follow-
ing:
• Gas may leak from a cigarette
lighter or spray can, and may lead to a fire.
• The temperature inside the vehicle may cause the plastic lenses and plastic material of glasses to
deform or crack.
• Soft drink cans may fracture, caus-
ing the contents to spray over the interior of the vehicle, and may also cause a short circuit in the vehicle’s
electrical components.
●Do not leave cigarette lighters in the
vehicle. If a cigarette lighter is in a place such as the glove box or on the floor, it may be lit accidentally
when luggage is loaded or the seat is adjusted, causing a fire.
●Do not attach adhesive discs to the windshield or windows. Do not place containers such as air fresh-
eners on the instrument panel or dashboard. Adhesive discs or con-tainers may act as lenses, causing
a fire in the vehicle.
●Do not leave a door or window
open if the curved glass is coated with a metallized film such as a sil-ver-colored one. Reflected sunlight
may cause the glass to act as a lens, causing a fire.
●Always apply the parking brake, stop the engine and lock the vehi-cle.
Do not leave the vehicle unat- tended while the engine is running.

doors until the vehicle reaches a safe and complete stop. Activation of the steering lock in this circumstance may
lead to an accident, resulting in death or serious injury.
NOTICE
■When starting the engine
●Do not race a cold engine.
●If the engine becomes difficult to start or stalls frequently, have your vehicle checked by any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer
immediately.
■Symptoms indicating a malfunc-
tion with the engine switch
If the engine switch seems to be oper- ating somewhat differently than usual,
such as the switch sticking slightly, there may be a malfunction. Contact any authorized Toyota retailer or
Toyota authorized repairer, or any reli- able repairer immediately.
