Tire Pressure Light
For vehicles with a Tire
Pressure Monitoring
System, this light comes
on briefly when the engine
is started. It provides
information about tire
pressures and the Tire
Pressure Monitoring
System.
When the Light is On Steady
This indicates that one or more of the tires is
significantly underinflated.
A tire pressure message in the Driver Information
Center (DIC), can accompany the light. SeeDriver
Information Center (DIC)
on page 4‑59for more
information. Stop and check the tires as soon as it is
safe to do so. If underinflated, inflate to the proper
pressure. See Inflation - Tire Pressure
on page 6‑57for more information.
When the Light Flashes First and Then is
On Steady
This indicates that there may be a problem with the Tire
Pressure Monitor System. The light flashes for about a
minute and stays on steady for the remainder of the
ignition cycle. This sequence repeats with every ignition
cycle. SeeTire Pressure Monitor Operation
on
page 6‑61for more information.
Malfunction Indicator Lamp
A computer system called OBD II (On-Board
Diagnostics-Second Generation) monitors operation
of the fuel, ignition, and emission control systems.
It ensures that emissions are at acceptable levels for
the life of the vehicle, helping to produce a cleaner
environment.
This light should come on
when the ignition is on,
but the engine is not
running, as a check to
show it is working. If it
does not, have the vehicle
serviced by your dealer.
If the Malfunction Indicator Lamp comes on and stays
on, while the engine is running, this indicates that there
is an OBD II problem and service is required.

THEFT ATTEMPTED
This symbol appears with
this message.
This message displays if the content theft-deterrent
system has detected a break-in attempt while you were
away from your vehicle. See Content Theft-Deterrent
on
page 3‑19for more information.
TIGHTEN GAS CAP
This message displays when the fuel cap has not been
fully tightened. Recheck the fuel cap to ensure that it is
on and tightened properly.
TIRE LEARNING ACTIVE
This message displays when the Tire Pressure Monitor
System (TPMS) is re-learning the tire positions on your
vehicle. The tire positions must be re-learned after
rotating the tires or after replacing a tire or sensor. See
Tire Inspection and Rotation
on page 6‑65,
Tire Pressure Monitor Systemon page 6‑60, and
Inflation - Tire Pressureon page 6‑57for more
information.
TRACTION CONTROL OFF
This message displays when the Traction Control
System (TCS) is turned off. Adjust your driving
accordingly. See Traction Control System (TCS)
on
page 5‑6for more information.
TRACTION CONTROL ON
This message displays when the Traction Control
System (TCS) is turned on. See Traction Control
System (TCS)
on page 5‑6for more information.
TRANSMISSION HOT IDLE ENGINE
Notice: If you drive the vehicle while the
transmission fluid is overheating and the
transmission temperature warning is displayed
on the instrument panel cluster and/or DIC, you
can damage the transmission. This could lead to
costly repairs that would not be covered by the
warranty. Do not drive your vehicle with overheated
transmission fluid or while the transmission
temperature warning is displayed.

Hydroplaning
Hydroplaning is dangerous. Water can build up under
your vehicle's tires so they actually ride on the water.
This can happen if the road is wet enough and you are
going fast enough. When your vehicle is hydroplaning, it
has little or no contact with the road.
There is no hard and fast rule about hydroplaning. The
best advice is to slow down when the road is wet.
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. SeeTireson page 6‑48.
.Turn off cruise control.
Before Leaving on a Long Trip
To prepare your vehicle for a long trip, consider having
it serviced by your dealer before departing.
Things to check on your own include:
.Windshield Washer Fluid:Reservoir full? Windows
clean —inside and outside?
.Wiper Blades: In good shape?
.Fuel, Engine Oil, Other Fluids: All levels checked?
.Lamps:Do they all work and are lenses clean?
.Tires:Are treads good? Are tires inflated to
recommended pressure?
.Weather and Maps: Safe to travel? Have
up-to-date maps?

Engine Oil
To ensure proper engine performance and long life,
careful attention must be paid to engine oil. Following
these simple, but important steps will help protect your
investment:
.Always use engine oil approved to the proper
specification and of the proper viscosity grade. See
“Selecting the Right Engine Oil.”
.Check the engine oil level regularly and maintain
the proper oil level. See “Checking Engine Oil”and
“When to Add Engine Oil.”
.Change the engine oil at the appropriate time. See
Engine Oil Life System on page 6‑18.
.Always dispose of engine oil properly. See “What
to Do With Used Oil.”
Checking Engine Oil
It is a good idea to check the engine oil level at each
fuel fill. In order to get an accurate reading, the vehicle
must be on level ground. The engine oil dipstick handle
is a yellow loop. See Engine Compartment Overview
on
page 6‑14for the location of the engine oil dipstick.
