For safety and security
■If the SRS airbags deploy (inflate)
●Slight abrasions, burns, bruising etc., may be sustained from SRS airbags,
due to the extremely high speed deployment (inflation) by hot gases.
● Bruising and slight abrasions may result from contact with a deploying
(inflating) SRS airbag.
● A loud noise and white powder will be emitted.
● Parts of the airbag module (steering wheel hub, airbag cover and inflator) as
well as the front seats, parts of the front and rear pillars, and roof side rail,
may be hot for several minutes. The airbag itself may also be hot.
● The windshield may crack.
● For Safety Connect subscribers, if the SRS airbags deploy or in the event of
a severe rear-end collision, the system is designed to send an emergency
call to the response center, notifying them of the vehicle’s location (without
needing to push the “SOS” button) and an agent will attempt to speak with
the occupants to ascertain the level of emergency and assistance required.
If the occupants are unable to communicate, the agent automatically treats
the call as an emergency and helps to dispatch the necessary emergency
services. ( P. 457)
■ SRS airbag deployment conditions (SRS front airbags)
●The SRS front airbags will deploy in the event of an impact that exceeds the
set threshold level (the level of force corresponding to an approximately 12 -
18 mph [20 - 30 km/h] frontal collision with a fixed wall that does not move or
deform).
However, this threshold velocity will be considerably higher in the following
situations: • If the vehicle strikes an object, such as a parked vehicle or sign pole, which can move or deform on impact
• If the vehicle is involved in an underride collision, such as a collision in which the front of the vehicle “underrides”, or goes under, the bed of a
truck
● Depending on the type of collision, it is possible that only the seat belt pre-
tensioners will activate.
● The SRS front airbags for the front pass enger will not activate if there is no
passenger sitting in the front passenger seat. However, the SRS front air-
bags for the front passenger may deploy if luggage is put in the seat, even if
the seat is unoccupied. ( P. 50)
● The SRS seat cushion airbag on the front passenger’s seat will not operate
if the occupant is not wearing a seat belt.

4-4. Refueling
Opening the fuel tank cap
●Close all the doors and windows, and turn the engine switch to the
“LOCK” position (vehicles without a smart key system) or off (vehi-
cles with a smart key system).
● Confirm the type of fuel.
■Fuel type
P. 607
■ Fuel tank opening for unleaded gasoline
To help prevent incorrect fueling, your vehicle has a fuel tank opening that
only accommodates the special nozzle on unleaded fuel pumps.
Perform the following steps to open the fuel tank cap:
Before refueling the vehicle
WARNING
■When refueling the vehicle
Observe the following precautions while refueling the vehicle. Failure to do
so may result in death or serious injury.
●After exiting the vehicle and before opening the fuel door, touch an
unpainted metal surface to discharge any static electricity. It is important to
discharge static electricity before refueling because sparks resulting from
static electricity can cause fuel vapors to ignite while refueling.
● Always hold the grips on the fuel tank cap and turn it slowly to remove it.
A whooshing sound may be heard when the fuel tank cap is loosened.
Wait until the sound cannot be heard before fully removing the cap.
In hot weather, pressurized fuel may spray out of the filler neck and cause
injury.
● Do not allow anyone that has not discharged static electricity from their
body to come close to an open fuel tank.
● Do not inhale vaporized fuel.
Fuel contains substances that are harmful if inhaled.
● Do not smoke while refueling the vehicle.
Doing so may cause the fuel to ignite and cause a fire.
● Do not return to the vehicle or touch any person or object that is statically
charged.
This may cause static electricity to build up, resulting in a possible ignition
hazard.

7-1. Maintenance and care
WARNING
■Water in the vehicle
●Do not splash or spill liquid in the vehicle.
Doing so may cause electrical components etc. to malfunction or catch
fire.
● Do not get any of the SRS components or wiring in the vehicle interior wet.
( P. 38)
An electrical malfunction may cause the airbags to deploy or not function
properly, resulting in death or serious injury.
■ Cleaning the interior (especially instrument panel)
Do not use polish wax or polish cleaner. The instrument panel may reflect
off the windshield, obstructing the driver’s view and leading to an accident,
resulting in death or serious injury.
NOTICE
■Cleaning detergents
●Do not use the following types of detergent, as they may discolor the vehi-
cle interior or cause streaks or damage to painted surfaces:
• Non-seat portions: Organic substances such as benzene or gasoline,
alkaline or acidic solutions, dye, and bleach
• Seats: Alkaline or acidic solutions, such as thinner, benzene, and alco- hol
● Do not use polish wax or polish cleaner. The instrument panel’s or other
interior part’s painted surface may be damaged.
■ Preventing damage to leather surfaces
Observe the following precautions to avoid damage to and deterioration of
leather surfaces.
●Remove any dust or dirt from leather surfaces immediately.
● Do not expose the vehicle to direct sunlight for extended periods of time.
Park the vehicle in the shade, especially during summer.
● Do not place items made of vinyl, plastic, or containing wax on the uphol-
stery, as they may stick to the leather surface if the vehicle interior heats
up significantly.

NOTICE
■Notice on fuel quality
●Do not use improper fuels. If improper fuels are used, the engine will be
damaged.
● Do not use leaded gasoline.
Leaded gasoline can cause damage to your vehicle’s catalytic converters
causing the emission control system to malfunction.
● Do not use gasohol other than that stated here.
Other gasohol may cause fuel system damage or vehicle performance
problems.
● Using unleaded gasoline with an octane number or rating lower than the
level previously stated will cause persistent heavy knocking.
At worst, this will lead to engine damage.
■ Fuel-related poor driveability
If poor driveability (poor hot starting, vaporization, engine knocking, etc.) is
encountered after using a different type of fuel, discontinue the use of that
type of fuel.
■ When refueling with gasohol
Take care not to spill gasohol. It can damage your vehicle’s paint.
