5-40 Instruments and Controls
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 trip odometer
reset stem for at least four seconds.
The trip odometer will display
the number of kilometers (km)
or miles (mi) 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 8 km (5 miles) before it
is started again, and then the
retro-active reset feature is
activated, the display will show
8 km (5 miles). As the vehicle
begins moving, the display will
then increase to 8.2 km (5.1 miles),
8.4 km (5.2 miles), etc.Transmission Temperature
Press the trip odometer reset
stem until TRANS TEMP displays.
This display shows the temperature
of the automatic transmission fluid
in either degrees Celsius (°C) or
degrees Fahrenheit (°F).
Trailer Gain and Output
On vehicles with the Integrated
Trailer Brake Control (ITBC) system,
the trailer brake display appears in
the DIC. Press the trip odometer
reset stem until TRAILER GAIN
and OUTPUT display.
TRAILER GAIN shows the trailer
gain setting. This setting can be
adjusted from 0.0 to 10.0 with either
a trailer connected or disconnected.
OUTPUT shows the power output
to the trailer any time a trailer with
electric brakes is connected. Output
is displayed in 0 to 10 bars. Dashes
may appear in the OUTPUT display.
To adjust trailer gain see
“Integrated
Trailer Brake Control System” under
Towing Equipment on page 9‑112
for more information.
Compass Zone Setting
This display allows for setting the
compass zone. See Compass on
page 5‑6 for more information.
Compass Recalibration
This display allows for calibrating
the compass. See Compass on
page 5‑6 for more information.
Oil Life
To access this display, the vehicle
must be in P (Park). Press the trip
odometer reset stem until OIL LIFE
REMAINING displays. This display
shows an estimate of the oil's
remaining useful life. If you see
99% OIL LIFE REMAINING on the
display, that means 99% of the
current oil life remains. The engine
oil life system will alert you to
change the oil on a schedule
consistent with your driving
conditions.

Driving Information
Defensive Driving
Defensive driving means “always
expect the unexpected.” The first
step in driving defensively is to wear
the safety belt. See Safety Belts on
page 3‑11.
{WARNING
Assume that other road users
(pedestrians, bicyclists, and other
drivers) are going to be careless
and make mistakes. Anticipate
what they might do and be ready.
In addition:
.Allow enough following
distance between you and
the driver in front of you.
.Focus on the task of driving.
(Continued)
WARNING (Continued)
Driver distraction can cause
collisions resulting in injury or
possible death. These simple
defensive driving techniques
could save your life.
Drunk Driving
{WARNING
Drinking and then driving is
very dangerous. Your reflexes,
perceptions, attentiveness, and
judgment can be affected by
even a small amount of alcohol.
You can have a serious —or
even fatal —collision if you drive
after drinking. Do not drink and
drive or ride with a driver who has
been drinking. Ride home in a
cab; or if you are with a group,
designate a driver who will not
drink.

9-24 Driving and Operating
Rocking Your Vehicle to Get
It Out
Turn the steering wheel left and
right to clear the area around the
front wheels. For four-wheel-drive
vehicles, shift into Four‐Wheel
High. For vehicles with StabiliTrak
®,
turn the traction control part of the
system off. Shift back and forth
between R (Reverse) and a forward
gear, spinning the wheels as little as
possible. To prevent transmission
wear, wait until the wheels stop
spinning before shifting gears.
Release the accelerator pedal
while shifting, and press lightly
on the accelerator pedal when
the transmission is in gear. Slowly
spinning the wheels in the forward
and reverse directions causes a
rocking motion that could free the vehicle. If that does not get the
vehicle out after a few tries, it might
need to be towed out. Recovery
hooks can be used, if the vehicle
has them. If the vehicle does need
to be towed out, see
Towing the
Vehicle on page 10‑103.
Recovery Hooks
{WARNING
These hooks, when used, are
under a lot of force. Always pull
the vehicle straight out. Never pull
on the hooks at a sideways angle.
The hooks could break off and
you or others could be injured
from the chain or cable
snapping back.Notice: Never use recovery
hooks to tow the vehicle.
Your vehicle could be damaged
and it would not be covered by
warranty.
For vehicles with recovery hooks at
the front of the vehicle, you can use
them if you are stuck off-road and
need to be pulled to some place
where you can continue driving.
