he nozzle opens and holds the flapper doors
while refueling.
5. F ill the vehicle with fuel – when the fuel nozzle
“
clicks” or shuts off the fuel tank is full.
6. Maintain nozzle in filler for five seconds to a
llow nozzle to drain.
7. Remove the fuel nozzle and close the fuel d
oor.
NOTE:
A funnel is provided (located in the trunk in the
s p
are tire area) to open the flapper doors to allow
for emergency refueling with a gas can.

WARNING!
Never have any smoking materials lit in or
near the vehicle when the fuel door is open or
the tank is being filled.
Never add fuel when the engine is running.
This is in violation of most state and federal
fire regulations and may cause the Malfunc -
tion Indicator Light to turn on.
A fire may result if fuel is pumped into a
portable container that is inside of a vehicle.
You could be burned. Always place fuel
containers on the ground while filling.
CAUTION!
To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.
WARNING!

SAFETY 149
NOTE:
The TPMS is not intended to replace normal tire
care and maintenance or to provide warning of
a tire failure or condition.
The TPMS should not be used as a tire pressure
gauge while adjusting your tire pressure.
Driving on a significantly underinflated tire
causes the tire to overheat and can lead to tire
failure. Underinflation also reduces fuel effi
-
ciency and tire tread life, and may affect the
v e

hicle’s handling and stopping ability.
The TPMS is not a substitute for proper tire
maintenance, and it is the driver’s responsibility
to maintain correct tire pressure using an accu -
rate tire pressure gauge, even if underinflation
h a

s not reached the level to trigger illumination
of the TPMS Warning Light.
Seasonal temperature changes will affect tire
pressure, and the TPMS will monitor the actual
tire pressure in the tire.
The Tire Pressure Monitoring System (TPMS) uses
w i

reless technology with wheel rim mounted
electronic sensors to monitor tire pressure levels.
Sensors, mounted to each wheel as part of the
valve stem, transmit tire pressure readings to the
receiver module
Ú page 254.
NOTE:
It is particularly important for you to check the tire
p r
essure in all of the tires on your vehicle monthly
and to maintain the proper pressure.
The TPMS consists of the following components:
Receiver module.
Four Tire Pressure Monitoring System sensors.
Various Tire Pressure Monitoring System
messages, which display in the instrument
cluster.
Tire Pressure Monitoring System Warning Light.
Tire Pressure Monitoring System Low
Pressure Warnings
The Tire Pressure Monitoring System
(TPMS) Warning Light will illuminate in
t h
e instrument cluster and a chime will
sound when tire pressure is low in one or
more of the four active road tires. In addition, the
instrument cluster will display an “Inflate to XX”
message and a graphic showing the pressure
values of each tire with the low tire pressure values
shown in a different color.
CAUTION!
The TPMS has been optimized for the original
equipment tires and wheels. TPMS pressures
and warning have been established for the tire
size equipped on your vehicle. Undesirable
system operation or sensor damage may
result when using replacement equipment
that is not of the same size, type, and/or style.
The TPMS sensor is not designed for use on
aftermarket wheels and may contribute to a
poor overall system performance or sensor
damage. Customers are encouraged to use
Original Equipment Manufacturer (OEM)
wheels to ensure proper TPMS feature opera -
tion.
Using aftermarket tire sealants may cause the
Tire Pressure Monitoring System (TPMS)
sensor to become inoperable. After using an
aftermarket tire sealant it is recommended
that you take your vehicle to an authorized
dealer to have your sensor function checked.
After inspecting or adjusting the tire pressure
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the
valve stem, which could damage the TPMS
sensor.

IN CASE OF EMERGENCY 189
REFUELING IN AN EMERGENCY –
IF EQUIPPED
The vehicle is equipped with a refueling funnel for
a Cap-Less Fuel System. If refueling is necessary,
while using an approved gas can, insert the
refueling funnel into the filler neck opening. Take
care to open both flappers with the funnel to avoid
spills.
NOTE:
In certain cold conditions, ice may prevent the fuel
d oor
from opening. If this occurs, lightly push on
the fuel door to break the ice buildup and
re-release the fuel door using the inside release
button. Do not pry on the door.

Refueling Funnel
Emergency Gas Can Refueling
Most gas cans will not open the flapper doors. A
f
u

nnel is provided to allow emergency refueling
with a gas can.
See below steps for refueling:

1. Retrieve funnel from the spare tire storage a
rea.

2. Insert funnel into same filler pipe opening as t
he fuel nozzle.

Inserting Funnel

3. E nsure funnel is inserted fully to hold flapper
d
oors open. 4. Pour fuel into funnel opening.
5
. Remove funnel from filler pipe, clean off prior t
o putting back in the spare tire storage area.
CAUTION!
To avoid fuel spillage and overfilling, do not “top
off” the fuel tank after filling.
WARNING!
Never have any smoking materials lit in or
near the vehicle when the fuel door is open or
the tank is being filled.
Never add fuel when the engine is running.
This is in violation of most state and federal
fire regulations and may cause the Malfunc -
tion Indicator Light to turn on.
A fire may result if fuel is pumped into a
portable container that is inside of a vehicle.
You could be burned. Always place fuel
containers on the ground while filling.

232 SERVICING AND MAINTENANCE
(Continued)
TIRES — GENERAL INFORMATION
Tire Pressure
Proper tire inflation pressure is essential to the
safe and satisfactory operation of your vehicle.
Four primary areas are affected by improper tire
pressure:
Safety
Fuel Economy
Tread Wear
Ride Comfort and Vehicle Stability
Safety Both underinflation and overinflation affect the
st
ability of the vehicle and can produce a feeling of
sluggish response or over responsiveness in the
steering.
NOTE:
Unequal tire pressures from side to side may
cause erratic and unpredictable steering
response.
Unequal tire pressure from side to side may
cause the vehicle to drift left or right.
Fuel Economy
Underinflated tires will increase tire rolling
r e

sistance resulting in higher fuel consumption.
Tread Wear
Improper cold tire inflation pressures can cause
a b

normal wear patterns and reduced tread life,
resulting in the need for earlier tire replacement. Ride Comfort And Vehicle Stability
Proper tire inflation contributes to a comfortable
r
i

de. Overinflation produces a jarring and
uncomfortable ride.
Tire Inflation Pressures
The proper cold tire inflation pressure is listed on
the driver's side B-pillar or rear edge of the driver's
side door.
At least once a month:
Check and adjust tire pressure with a good
quality pocket-type pressure gauge. Do not
make a visual judgement when determining
proper inflation. Tires may look properly inflated
even when they are underinflated.
Inspect tires for signs of tire wear or visible
damage.
Inflation pressures specified on the placard are
a l

ways “cold tire inflation pressure”. Cold tire
inflation pressure is defined as the tire pressure
after the vehicle has not been driven for at least
3 hours, or driven less than 1 mile (1.6 km) after
WARNING!
Improperly inflated tires are dangerous and
can cause collisions.
Underinflation increases tire flexing and can
result in overheating and tire failure.
Overinflation reduces a tire's ability to cushion
shock. Objects on the road and chuckholes
can cause damage that result in tire failure.
Overinflated or underinflated tires can affect
vehicle handling and can fail suddenly,
resulting in loss of vehicle control.
Unequal tire pressures can cause steering
problems. You could lose control of your
vehicle.
Unequal tire pressures from one side of the
vehicle to the other can cause the vehicle to
drift to the right or left.
Always drive with each tire inflated to the
recommended cold tire inflation pressure.
WARNING!
CAUTION!
After inspecting or adjusting the tire pressure,
always reinstall the valve stem cap. This will
prevent moisture and dirt from entering the
valve stem, which could damage the valve stem.
