Your vehicle is equipped with a tire
pressure monitoring system (TPMS)
that turns on every time you start the
engine and monitors the pressure in
your tires while driving.
Each tire has its own pressure
sensor. If the air pressure of a tire
becomes significantly low, the sensor
in that tire immediately sends a
signal that causes the low tire
pressure/TPMS indicator in the
instrument panel to come on. If this
happens, you will see which tire is
losing pressure on the multi-
information display along with a
‘‘CHECK TIRE PRESSURE ’’
message.
Low Tire Pressure/TPMS
Indicator
When the low tire pressure/TPMS
indicator is on, one or more of your
tires is significantly underinflated.
You should stop and check your tires
as soon as possible, and inflate them
to the proper pressure as indicated
on the vehicle's tire information
placard.
It is possible that the pressures
shown on the multi-information
display and the pressures you
manually measure are slightly
different.
If the difference is significant or you
cannot make the low tire pressure/
TPMS indicator and message on the
multi-information display go out after
inflating the tires to the specified
values, have your dealer check the
system as soon as possible. If you think you can safely drive a
short distance to a service station,
proceed slowly to the station, then
inflate the tire to the recommended
pressure.
If the tire is flat, or if the tire pressure
is too low to continue driving, replace
the tire with the compact spare tire
(see page 454).
Driving on a significantly under-
inflated tire causes the tire to
overheat and can lead to tire failure.
Under-inflation also reduces fuel
efficiency and tire tread life, and may
affect the vehicle's handling and
stopping ability.
Because tire pressure varies by
temperature and other conditions,
the low tire pressure/TPMS
indicator may come on unexpectedly.

Driving on HillsWhen climbing hills, closely watch
your temperature gauge (see page
78). If it nears the H (Hot) mark, turn
the A/C off, reduce speed and, if
necessary, pull to the side of the road
to let the engine cool.
When driving down hills, reduce
your speed, and shift down to S
position, or use the paddle shifters to
the lower gear (3, 2 or 1)in the S
position. When towing a trailer, do
not‘‘ride ’’the brakes, and remember,
it will take longer to slow down and
stop when towing a trailer.
If you must stop when facing uphill,
use the foot brake or parking brake.
Do not try to hold the vehicle in place
by pressing on the accelerator, as
this can cause the automatic
transmission to overheat.
Handling Crosswinds and BuffetingCrosswinds and air turbulence
caused by passing trucks can disrupt
your steering and cause the trailer to
sway. When being passed by a large
vehicle, keep a constant speed, and
steer straight ahead. Do not try to
make quick steering or braking
corrections.
Backing UpAlways drive slowly and have
someone guide you when backing
up. Grip the
bottom
of the steering
wheel; then turn the wheel to the left
to get the trailer to move to the left,
and turn the wheel right to move the
trailer to the right.
ParkingFollow all normal precautions when
parking, including putting the
transmission in Park and firmly
setting the parking brake. Also, place
wheel chocks at each of the trailer's
tires.Towing Your VehicleYour vehicle is not designed to be
towed behind a motor home. If your
vehicle needs to be towed in an
emergency, see page 475.

This section covers the more
common problems that motorists
experience with their vehicles. It
gives you information about how to
safely evaluate the problem and what
to do to correct it. If the problem has
stranded you on the side of the road,
you may be able to get going again. If
not, you will also find instructions on
getting your vehicle towed.Compact Spare Tire

The reading of the vehicle's
temperature gauge on the multi-
information display should stay in the
midrange. If it climbs to the H (Hot)
mark, you should determine the
reason (hot day, driving up a steep
hill, etc.).
If the coolant temperature rises to
224°F (118°C) or more, the
temperature gauge will appear on the
display and blink for several times.
At the same time, the beeper will
sound once.
If your vehicle overheats, you should
take immediate action. The only
indication may be the temperature
gauge climbing to the H (Hot) mark.
Or you may see steam or spray
coming from under the hood.
Driving with the temperature gauge
reading at the H (Hot) mark can cause
serious damage to the engine.
Steam and spray from an
overheated engine can
seriously scald you.
Do not open the hood if steam
is coming out.
1. Safely pull to the side of the road. Put the transmission in Park, and
set the parking brake. Turn off all
accessories, and turn on the
hazard warning lights. 2. If you see steam and/or spray
coming from under the hood, turn
off the engine. Wait until you see
no more signs of steam or spray,
then open the hood.
3. If you do not see steam or spray, leave the engine running and
watch the temperature gauge. If
the high heat is due to
overloading, the engine should
start to cool down almost
immediately. If it does, wait until
the temperature gauge comes
down to the midpoint, then
continue driving.
4. If the temperature gauge reading stays at the H (Hot) mark, turn off
the engine.

5. Look for any obvious coolantleaks, such as a split radiator hose.
Everything is still extremely hot,
so use caution. If you find a leak, it
must be repaired before you
continue driving (see Emergency
Towing on page 475).
6. If you do not find an obvious leak, check the coolant level in the
radiator reserve tank. Add coolant
if the level is below the MIN mark.
7. If there was no coolant in the reserve tank, you may need to add
coolant to the radiator. Let the
engine cool down until the reading
reaches the middle of the
temperature gauge or lower before
checking the radiator.
Removing the radiator 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 radiator cap.
8. Using gloves or a large heavy cloth, turn the radiator cap
counterclockwise, without pushing
down, to the first stop. After the
pressure releases, push down on
the cap, and turn it until it comes
off. 9. Start the engine, and set the
temperature to maximum heat
(climate control to AUTO at
‘‘
’’). Add coolant to the radiator
up to the base of the filler neck. If
you do not have the proper coolant
mixture available, you can add
plain water. Remember to have the
cooling system drained and refilled
with the proper mixture as soon as
you can.
10. Put the radiator cap back on tightly. Run the engine, and watch
the temperature gauge. If it goes
back to the H mark, the engine
needs repair (see Emergency
Towing on page 475).
11. If the temperature stays normal, check the coolant level in the
radiator reserve tank. If it has gone
down, add coolant to the MAX
mark. Put the cap back on tightly.
