Tire Pressure Monitor
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The low tire pressure warning light
alerts to a significant loss in
pressure of one of the vehicle's
tires. If the warning light comes on,
stop as soon as possible and inflate
the tires to the recommended
pressure shown on the Tire and
Loading Information label. See
Vehicle Load Limits 0184. The
warning light will remain on until the
tire pressure is corrected.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as the vehicle is driven. This
may be an early indicator that the
tire pressures are getting low and
the tires need to be inflated to the
proper pressure.
The TPMS does not replace normal
monthly tire maintenance. Maintain
the correct tire pressures.
See Tire Pressure Monitor System
0 286.
Tire Fill Alert (If Equipped)
This feature provides visual and
audible alerts outside the vehicle to
help when inflating an underinflated tire to the recommended cold tire
pressure. See
“Tire Fill Alert (If
Equipped)” underTire Pressure
Monitor Operation 0287.
Fuel (2.5L Engine)
Regular Unleaded Fuel
Use only Regular 87 octane —
(R+M)/2 —or higher unleaded
gasoline in your vehicle. TOP TIER
Detergent Gasoline is
recommended. Do not use gasoline
with an octane rating lower as it will
result in reduced performance and
lower fuel economy. See
Recommended Fuel (2.5L Engine)
0 230 orRecommended Fuel (2.0L
Engine) 0230.

138 Instruments and Controls
When the Light Is On Steady
This indicates that one or more of
the tires are significantly
underinflated.
A Driver Information Center (DIC)
tire pressure message may also
display. Stop as soon as possible,
and inflate the tires to the pressure
value shown on the Tire and
Loading Information label. SeeTire
Pressure 0284.
When the Light Flashes First and
Then Is On Steady
If the light flashes for about a minute
and then stays on, there may be a
problem with the TPMS. If the
problem is not corrected, the light
will come on at every ignition cycle.
See Tire Pressure Monitor
Operation 0287.Engine Oil Pressure Light
Caution
Lack of proper engine oil
maintenance can damage the
engine. Driving with the engine oil
low can also damage the engine.
The repairs would not be covered
by the vehicle warranty. Check
the oil level as soon as possible.
Add oil if required, but if the oil
level is within the operating range
and the oil pressure is still low,
have the vehicle serviced. Always
follow the maintenance schedule
for changing engine oil.
This light should come on briefly as
the engine is started. If it does not
come on, have the vehicle serviced
by your dealer. If the light comes on and stays on, it
means that oil is not flowing through
the engine properly. The vehicle
could be low on oil and might have
some other system problem. See
your dealer.
Low Fuel Warning Light
This light is near the fuel gauge and
comes on briefly when the ignition is
turned on as a check to show it is
working.
It also comes on when the fuel tank
is low on fuel. The light turns off
when fuel is added. If it does not,
have the vehicle serviced.

182 Driving and Operating
Other Rainy Weather Tips
Besides slowing down, other wet
weather driving tips include:
.Allow extra following distance.
. Pass with caution.
. Keep windshield wiping
equipment in good shape.
. Keep the windshield washer fluid
reservoir filled.
. Have good tires with proper
tread depth. See Tires0277.
. Turn off cruise control.
Hill and Mountain Roads
Driving on steep hills or through
mountains is different than driving
on flat or rolling terrain. Tips include:
.Keep the vehicle serviced and in
good shape.
. Check all fluid levels and brakes,
tires, cooling system, and
transmission.
. Shift to a lower gear when going
down steep or long hills.
{Warning
Using the brakes to slow the
vehicle on a long downhill slope
can cause brake overheating, can
reduce brake performance, and
could result in a loss of braking.
Shift the transmission to a lower
gear to let the engine assist the
brakes on a steep downhill slope.
{Warning
Coasting downhill in N (Neutral)
or with the ignition off is
dangerous. This can cause
overheating of the brakes and
loss of steering assist. Always
have the engine running and the
vehicle in gear.
. Drive at speeds that keep the
vehicle in its own lane. Do not
swing wide or cross the
center line. .
Be alert on top of hills;
something could be in your lane
(e.g., stalled car, crash).
. Pay attention to special road
signs (e.g., falling rocks area,
winding roads, long grades,
passing or no-passing zones)
and take appropriate action.
Winter Driving
Driving on Snow or Ice
Snow or ice between the tires and
the road creates less traction or
grip, so drive carefully. Wet ice can
occur at about 0 °C (32 °F) when
freezing rain begins to fall. Avoid
driving on wet ice or in freezing rain
until roads can be treated.
For Slippery Road Driving:
.Accelerate gently. Accelerating
too quickly causes the wheels to
spin and makes the surface
under the tires slick.
. Turn on Traction Control. See
Traction Control/Electronic
Stability Control 0203.

Tire and Loading Information
Label
Example Label
A vehicle-specific Tire and
Loading Information label is
attached to the center pillar
(B-pillar). The tire and loading
information label shows the
number of occupant seating
positions (1), and the maximum
vehicle capacity weight (2) in
kilograms and pounds.The Tire and Loading
Information label also shows the
size of the original equipment
tires (3) and the recommended
cold tire inflation pressures (4).
For more information on tires
and inflation see
Tires0277
and Tire Pressure 0284.
There is also important loading
information on the vehicle
Certification/Tire label. It may
show the Gross Vehicle Weight
Rating (GVWR) and the Gross
Axle Weight Rating (GAWR) for
the front and rear axle. See
“Certification/Tire Label” later in
this section.
“Steps for Determining Correct
Load Limit–
1.
Locate the statement "The
combined weight of
occupants and cargo should
never exceed XXX kg or
XXX lbs." on your vehicle’s
placard.
2.Determine the combined
weight of the driver and
passengers that will be
riding in your vehicle.
3.Subtract the combined
weight of the driver and
passengers from XXX kg or
XXX lbs.
4.The resulting figure equals
the available amount of
cargo and luggage load
capacity. For example, if the
"XXX" amount equals
1400 lbs. and there will be
five 150 lb passengers in
your vehicle, the amount of
available cargo and luggage
load capacity is 650 lbs.
(1400-750 (5 x 150) =
650 lbs.)

Driving and Operating 187
Example 3
1.Vehicle Capacity Weight
for Example 3 = 453 kg
(1,000 lbs).
2.Subtract Occupant
Weight @ 91 kg
(200 lbs) × 5 = 453 kg
(1,000 lbs).
3.Available Cargo Weight
= 0 kg (0 lbs).
Refer to the vehicle's tire and
loading information label for
specific information about the
vehicle's capacity weight and
seating positions. The combined weight of the driver, passengers,
and cargo should never exceed
the vehicle's capacity weight.
Certification/Tire Label
Label Example
A vehicle-specific Certification/
Tire label is attached to the
center pillar (B-pillar).
The label may show the size of
the vehicle's original tires and
the inflation pressures needed to
obtain the gross weight capacity
of the vehicle. The label shows
the gross weight capacity of the
vehicle. This is called the GrossVehicle Weight Rating (GVWR).
The GVWR includes the weight
of the vehicle, all occupants,
fuel, and cargo.
The Certification/Tire label may
also show the maximum weights
for the front and rear axles,
called the Gross Axle Weight
Rating (GAWR). To find out the
actual loads on the front and
rear axles, weigh the vehicle at
a weigh station. Your dealer can
help with this. Be sure to spread
the load equally on both sides of
the centerline.
CautionOverloading the vehicle may
cause damage. Repairs would not
be covered by the vehicle
warranty. Do not overload the
vehicle.

240 Driving and Operating
outside of this range. Always refer
to the trailer owner’s manual for the
recommended trailer tongue weight
for each trailer. Never exceed the
maximum loads for your vehicle,
hitch and trailer.
After loading the trailer, separately
weigh the trailer and then the trailer
tongue to see if the weights are
appropriate for your vehicle. If the
trailer weight is too high, it may be
possible to trasfer some of the
cargo into your vehicle. If the trailer
tongue weight is too high or too low,
it may be possible to rearrange
some of the cargo inside of the
trailer.
Do not exceed the maximum
allowable tongue weight for your
vehicle. Use the shortest hitch
extension available to position the
hitch ball closer to your vehicle. This
will help reduce the effect of the
trailer tongue weight on the trailer
hitch and the rear axle.
If a cargo carrier is used in the
trailer hitch receiver, choose a
carrier that positions the load as
close to the vehicle as possible. Make sure the total weight,
including the carrier, is no more than
half of the maximum allowable
tongue weight for the vehicle or
227 kg (500 lb), whichever is less.
Ask your dealer for trailering
information or assistance.
Towing Equipment
Hitches
Always use the correct hitch
equipment for your vehicle.
Crosswinds, large trucks going by,
and rough roads can affect the
trailer and the hitch.
Never attach rental hitches or other
bumper-type hitches. Only use
frame-mounted hitches that do not
attach to the bumper.
Always seal any holes in your
vehicle if the trailer hitch removed.
If not sealed, dirt, water, and carbon
monoxide (CO) from the exhaust
may enter your vehicle. See
Engine
Exhaust 0196. Consider using mechanical sway
controls with any trailer. Ask a
trailering professional about sway
controls or refer to the trailer
manufacturer's recommendations
and instructions.
Tires
.
Do not tow a trailer while using a
compact spare tire on the
vehicle.
. Tires must be properly inflated to
support loads while towing a
trailer. See Tires0277 for
instructions on proper tire
inflation.
Safety Chains
Always attach chains between the
vehicle and the trailer, and attach
the chains to the holes on the trailer
hitch platform. Instructions about
safety chains may be provided by
the hitch manufacturer or by the
trailer manufacturer.
Cross the safety chains under the
tongue of the trailer to help prevent
the tongue from contacting the road
if it becomes separated from the
