5-2. Steps to take in an emergency
Start the engine of the second vehicle. Increase the engine
speed slightly and maintain at that level for approximately 5
minutes to recharge the battery of your vehicle.
Vehicles with a smart key sy
stem only: Open and close any
of the doors of your vehicle with the “ENGINE START
STOP” switch off.
Vehicles without a smart key system: Maintain the engine
speed of the second vehicle and turn the engine switch to
the “ON” position, then start the vehicle's engine.
Vehicles with a smart key system: Maintain the engine
speed of the second vehicle and turn the “ENGINE START
STOP” switch to IGNITION ON mode, then start the vehi-
cle's engine.
Once the vehicle’s engine has started, remove the jumper
cables in the exact reverse order in which they were con-
nected.
Once the engine starts, have the vehicle checked at your Toyota
dealer as soon as possible.STEP 2

446 5-2. Steps to take in an emergency
■Starting the engine when the battery is discharged
The engine cannot be started by push-starting.
■ Avoiding a discharged battery
●Turn off the headlights and the air conditioning system while t he engine is
off.
● Turn off any unnecessary electrical components when the vehicle is run-
ning at a low speed for an extended period, such as in heavy traffic, etc.
■ Charging the battery
The electricity stored in the battery will discharge gradually even when the
vehicle is not in use, due to natural discharge and the draining effects of cer-
tain electrical appliances. If the vehicle is left for a long t ime, the battery may
discharge, and the engine may be unable to start. (The battery recharges
automatically during driving.)
■ Precautions when the battery is discharged (vehicles with a sma rt key
system)
● In some cases, it may not be possible to unlock the doors using the smart
key system when the battery is discharged. Use the wireless remote con-
trol or the mechanical key to lock or unlock the doors.
● The engine may not start on the first attempt after the battery has
recharged but will start normally after the second attempt. This is not a
malfunction.
● The “ENGINE START STOP” switch mode is memorized by the vehicle .
When the battery is reconnected, the system will return to the mode it
was in before the battery was discharged. Before disconnecting the bat-
tery, turn the “ENGINE START STOP” switch off.
If you are unsure what mode the “ENGINE START STOP” switch was in
before the battery discharged, be especially careful when reconnecting
the battery.

WARNING
■
Avoiding battery fires or explosions
Observe the following precautions to prevent accidentally ignit ing the flam-
mable gas that may be emitted from the battery.
● Make sure the jumper cable is connected to the correct terminal and that it
is not unintentionally in contact with any part other than the intended termi-
nal.
● Do not allow the jumper cables to come into contact with the “+ ” and “-” ter-
minals.
● Do not allow open flame or use matches, cigarette lighters or s moke near
the battery.
■ Battery precautions
The battery contains poisonous and corrosive acidic electrolyte , while
related parts contain lead and lead compounds. Observe the following pre-
cautions when handling the battery.
● When working with the battery, always wear safety glasses and t ake care
not to allow any battery fluids (acid) to come into contact wit h skin, clothing
or the vehicle body.
● Do not lean over the battery.
● In the event that battery fluid comes into contact with the ski n or eyes,
immediately wash the affected area with water and seek medical attention.
Place a wet sponge or cloth over the affected area until medica l attention
can be received.
● Always wash your hands after handling the battery support, term inals, and
other battery-related parts.
● Do not allow children near the battery.
■ To prevent damage to the vehicle
Do not pull- or push-start the vehicle as the three-way catalytic converter
may overheat and become a fire hazard.

If your vehicle overheats
Correction proceduresStop the vehicle in a safe place and turn off the air condition -
ing system, and then stop the engine.
If you see steam:
Carefully lift the hood after the steam subsides.
If you do not see steam:
Carefully lift the hood.
After the engine has cooled
down sufficiently, inspect the
hoses and radiator core (radia-
tor) for any leaks.
Radiator
Cooling fans
If a large amount of coolant leaks,
immediately contact your Toyota
dealer.
The following may indicate that your vehicle is overheating.
●Vehicles with a monochrome mu lti-information display: The
engine coolant temperature gauge ( P. 191) enters the red
zone or a loss of engine power is experienced (for example, the
vehicle speed does not increase).
Vehicles with a color multi-information display: The high engin e
coolant temperature warning light ( P. 194) flashes or illumi-
nates or a loss of engine power i s experienced (for example, the
vehicle speed does not increase).
● Steam comes out from under the hood.

Fuel infor mation
■Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your Toyota has a fuel tank opening that
only accommodates the special nozzle on unleaded fuel pumps.
■ If your engine knocks
●Consult your Toyota dealer.
● You may occasionally notice light knocking for a short time whi le acceler-
ating or driving uphill. This is normal and there is no need fo r concern.
The engine is designed to operate at maximum performance using
unleaded gasoline with an octane rating of 93 (98 RON) or highe r. I f
an octane rating of 93 (98 RON) fuel is not readily available i n your
area, unleaded gasoline with an octane rating of 91 (95 RON) may be
used with no detriment to engine durability or driveability. Ho wever,
you may notice a slight decrease in maximum engine performance
and you may hear some knocking (p inging) of an engine while using
an octane rating of 91 (95 RON) fuel.
If the octane rating is less than 91, damage to the engine may occur
and may void the vehicle warranty.

■
Gasoline quality
In very few cases, driveability problems may be caused by the b rand of gas-
oline you are using. If driveability problems persist, try chan ging the brand of
gasoline. If this does not correct the problem, consult your Toyota dealer.
■ Fuel octane rating
This octane rating is the average of the Research Octane and Mo tor Octane
numbers and is commonly referred to as the Anti Knock Index.
Using a gasoline with a lower octane rating can cause persistent and heavy
knocking, which can damage the engine. Do not be concerned if y our vehi-
cle sometimes knocks lightly when you drive up a hill or when y ou acceler-
ate. Contact your Toyota dealer if you use a fuel with the spec ified octane
rating and your vehicle knocks heavily or persistently.
■ Gasoline for California-certified LEV
If your vehicle was certified to California’s low emission vehi cle (LEV) stan-
dards as indicated on the underhood tune-up label, it is design ed to optimize
engine and emission performance with gasoline that meets the cl ean burn-
ing low-sulfur California gasoline specifications. If you live in any other state
than California, your vehicle will operate on gasoline meeting Federal speci-
fications. Gasoline sold outside California is permitted to have higher sulfur
levels, which may affect the performance of your vehicle’s cata lytic converter
and may produce a sulfur exhaust odor or smell. Toyota recommends that
you try a different brand of unleaded gasoline having lower sul fur to deter-
mine if the problem is fuel related before returning your vehic le to an autho-
rized dealer for service.
