T(Vehicle Information):Press this button to display
the oil life, units, tire pressure readings for vehicles with
the Tire Pressure Monitor System (TPMS), engine hours,
Tire Pressure Monitor System (TPMS) programming for
vehicles with the TPMS and without a Remote Keyless
Entry (RKE) transmitter, compass zone and compass
calibration on vehicles with this feature, and RKE
transmitter programming.
U(Customization):Press this button to customize the
feature settings on your vehicle. SeeDIC Vehicle
Customization on page 3-59for more information.
V(Set/Reset):Press this button to set or reset certain
functions and to turn off or acknowledge messages
on the DIC.
Trip/Fuel Menu Items
3
(Trip/Fuel):Press this button to scroll through the
following menu items:
Odometer
Press the trip/fuel button until XX mi (Km) displays.
This display shows the distance the vehicle has been
driven in either miles (mi) or kilometers (km).
Trip Odometers
Press the trip/fuel button until A or B displays. This
display shows the current distance traveled in either
miles (mi) or kilometers (km) since the last reset for each
trip odometer. Both trip odometers can be used at the
same time.
Each trip odometer can be reset to zero separately by
pressing the set/reset button while the desired trip
odometer is displayed.
The trip odometer has a feature called the retro-active
reset. This can be used to set the trip odometer to the
number of miles (kilometers) driven since the ignition was
last turned on. This can be used if the trip odometer is not
reset at the beginning of the trip.
To use the retro-active reset feature, press and hold
the set/reset button for at least four seconds. The trip
odometer will display the number of miles (mi) or
kilometers (km) driven since the ignition was last turned
on and the vehicle was moving. Once the vehicle begins
moving, the trip odometer will accumulate mileage. For
example, if the vehicle was driven 5 miles (8 km) before it
is started again, and then the retro-active reset feature is
activated, the display will show 5 miles (8 km). As the
vehicle begins moving, the display will then increase to
5.1 miles (8.2 km), 5.2 miles (8.4 km), etc.

STARTING DISABLED SERVICE
THROTTLE
This message displays if the starting of the engine is
disabled due to the electronic throttle control system.
Have your vehicle serviced by your dealer/retailer
immediately.
This message only appears while the ignition is in
ON/RUN, and will not disappear until the problem is
resolved.
This message cannot be acknowledged.
TIGHTEN GAS CAP
This message may display and a chime may be heard
along with the check engine light on the instrument
panel cluster if the vehicle’s fuel cap is not tightened
properly. SeeMalfunction Indicator Lamp on page 3-36.
Reinstall the fuel cap fully. SeeFilling the Tank on
page 5-10. The diagnostic system can determine if the
fuel cap has been left off or improperly installed. A
loose or missing fuel cap allows fuel to evaporate into
the atmosphere. A few driving trips with the cap properly
installed should turn this light and message off.
TIRE LEARNING ACTIVE
If your vehicle has the Tire Pressure Monitor System
(TPMS), this message displays when the system is
re-learning the tire positions on your vehicle. SeeDIC
Operation and Displays on page 3-43for more
information. 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 5-69,Tire Pressure
Monitor System on page 5-64, andInflation - Tire
Pressure on page 5-62for more information.
TRACTION CONTROL OFF
If your vehicle has StabiliTrak, this message displays
when the Traction Control System (TCS) is turned
off. Adjust your driving accordingly. SeeStabiliTrak
®
System on page 4-6for more information.
TRANSMISSION HOT IDLE ENGINE
Notice:If you drive your vehicle while the
transmission uid 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
your warranty. Do not drive your vehicle with
overheated transmission uid 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. SeeTires
on page 5-54.
•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/retailer 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?

your vehicle’s capacity weight and seatingpositions. The combined weight of the driver,
passengers, and cargo should never exceed
your vehicle’s capacity weight.
Certication/Tire Label
A vehicle specific Certification/Tire label is found on
the rear edge of the driver’s door. The label shows
the size of your vehicle’s original tires and the
inflation pressures needed to obtain the gross
weight capacity of your vehicle. This is called Gross
Vehicle Weight Rating (GVWR). The GVWR
includes the weight of the vehicle, all occupants,
fuel, and cargo.

Checking Engine Oil
It is a good idea to check the engine oil every time you
get fuel. In order to get an accurate reading, the oil
must be warm and the vehicle must be on level ground.
The engine oil dipstick handle is a yellow loop.
SeeEngine Compartment Overview on page 5-14
for the location of the engine oil dipstick.
1. Turn off the engine and give the oil several minutes
to drain back into the oil pan. If you do not do this,
the oil dipstick might not show the actual level.
2. Pull out the dipstick and clean it with a paper towel
or cloth, then push it back in all the way. Remove it
again, keeping the tip down, and check the level.
