• Greater than 25 psi (175 kPa), but less
than front: 35 psi (240 kPa)/rear: 33 psi
(230 kPa):
Turn the air compressor on to inflate the
tire until the tire pres sure reaches front: 35
psi (240 kPa)/rear: 33 psi (230 kPa).
2Inflating an Under-inflated Tire P. 645
Then drive carefully for 10 more minutes
or until you reach the nearest service
station, whichever is sooner.
Do not exceed 50 mph (80 km/h). If you
have not reached a service station, stop
and check the tire pressure.
u You should repeat this procedure as
long as the air pressure is within this
range.
7. Unplug the kit from the accessory power
socket.
8. Unscrew the sealant/air hose from the tire
valve stem.
Reinstall the valve cap.
9. Press the pressure relief button until the
gauge returns to 0 psi (0 kPa).
10. Repackage and properly stow the kit.

Changing a Flat Tire
If a tire goes flat while driving, grasp the steering wheel firmly, and brake gradually
to reduce speed. Then, stop in a safe place. Replace the flat tire with a compact
spare tire. Go to a dealer as soon as possible to have th e full-size tire repaired or
replaced.
1. Park the vehicle on firm, level, and non- slippery surface and apply the parking
brake.
2. Put the transmission into

*1: Models with the smart entry system have an ENGINE START/STOP button instead of an
ignition switch.
Models with a compact spare tire
1 Changing a Flat Tire
Follow compact spare precautions:
Periodically check the tire pressure of the compact
spare. It should be set to the specified pressure.
Specified Pressure: 60 psi (420 kPa, 4.2 kgf/cm
2)
When driving with the compact spare tire, keep the
vehicle speed under 50 mph (80 km/h). Replace with
a full-size tire as soon as possible.
The compact spare tire and wheel in your vehicle are
specifically for this model. Do not use them with
another vehicle. Do not us e another type of compact
spare tire or wheel with your vehicle.
Do not mount tire chains on a compact spare tire.
If a chain-mounted front tire goes flat, remove one of
the full-size rear tires and replace it with the compact
spare tire. Remove the flat front tire and replace it
with the full-size tire that was removed from the rear.
Mount the tire chains on the front tire.
NOTICE
Do not use the jack if it doesn’t work properly. Call
your dealer or a prof essional towing service.
The subwoofer
*, a large black enclosure, is located
on the rear right side. Do not store anything in this
area. Doing so may compromise vehicle audio
performance.

then open the hood. 1.Open the cover on your vehicle’s battery
positive + terminal.
2. Connect the first jump er cable to your
vehicle’s battery + terminal.
3. Connect the other end of the first jumper
cable to the booster battery + terminal.
u Use a 12-volt booster battery only.
u When using an automotive battery
charger to boost your 12-volt battery,
select a lower charging voltage than 15-
volt. Check the charger manual for the
proper setting.
4. Connect the second jumper cable to the
booster battery - terminal.
■Jump Starting Procedure1If the Battery Is Dead
Securely attach the jumper cables clips so that they
do not come off when the e ngine vibrates. Also be

to any other part.
6. If your vehicle is connected to another
vehicle, start the assisting vehicle’s engine
and increase its rpm slightly.
7. Attempt to start your ve hicle’s engine. If it
turns over slowly, check that the jumper
cables have good metal-to-metal contact.1 If the Battery Is Dead

uuOverheating uHow to Handle Overheating
Handling the Unexpected
■Next thing to do
1.Check that the cooling fan is operating and
stop the engine once the Stop Driving
When Safe. Engine Temperature Too
Hot message on the driver information
interface goes off.
u If the cooling fan is not operating,
immediately stop the engine.
2. Once the engine has cooled down, inspect
the coolant level and check the cooling
system components for leaks.
u If the coolant level in the reserve tank is
low, add coolant until it reaches the MAX
mark.
u If there is no coolant in the reserve tank,
check that the radiator is cool. Cover the
radiator cap with a heavy cloth and open
the cap. If necessary, add coolant up to
the base of the filler neck, and put the
cap back on.
■Last thing to do
Once the engine has cooled sufficiently, restart it and check the temperature gauge.
If the temperature gauge pointer has gone down, resume driving. If it has not gone
down, contact a dealer for repairs.
1 How to Handle Overheating
If the coolant is leaking, contact a dealer for repairs.
Use water as an emergen cy/temporary measure only.
Have a dealer flush the system with proper antifreeze
as soon as possible.
3WARNING
Removing the reserve tank cap while the
engine is hot can cause the coolant to spray
out, seriously scalding you.
Always let the engine and radiator cool
down before removing the reserve tank
cap.
