• Greater than 25 psi (175 kPa), but less
than 33 psi (230 kPa):
Turn the air compressor on to inflate
the tire until the tire pressure reaches
33 psi (230 kPa).
• Greater than 25 psi (175 kPa), but less
than 36 psi (250 kPa):
Turn the air compressor on to inflate
the tire until the tire pressure reaches
36 psi (250 kPa).
2 Inflating an Under-inflated Tire
P. 604
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.

Jump Starting
Turn off the power to electric devices, such as audio and lights. Turn off the engine,
then open the hood. 1.Connect the first jump er cable to your
vehicle’s battery + terminal.
2. 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.
3. Connect the second jumper cable to the
booster battery - terminal.
4. Connect the other end of the second
jumper cable to the engine mounting bolt
as shown. Do not connect this jumper cable
to any other part.
5. If your vehicle is connected to another
vehicle, start the assisting vehicle’s engine
and increase its rpm slightly.
6. Attempt to start your vehicle’s engine. If it
turns over slowly, check that the jumper
cables have good metal-to-metal contact.
■Jump Starting Procedure1Jump Starting
Securely attach the jumper cables clips so that they
do not come off when the e ngine vibrates. Also be
careful not to tangle the ju mper cables or allow the
cable ends to touch each other while attaching or
detaching the jumper cables.
Battery performance degrades in cold conditions and
may prevent the engi ne from starting.

1.Check that the cooling fan is operating and
stop the engine once the temperature
gauge comes down.
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, re start it and check the temperature gauge.
If the temperature gauge has gone down, resu me 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 emergency/temporary measure only.
Have a dealer flush the system with proper antifreeze
as soon as possible.
