Save
Pressing the SAVE button will let you save the timer data
for Recent, Last, and Best recorded times to an inserted
USB flash drive.
The Timers pages contain:
Reaction Time : Measures the driver's reaction time for
launching the vehicle against a simulated drag strip
timing light (behavior modeled after 500 Sportsman
Tree) displayed in the instrument cluster display.
NOTE:Drag timers (RT, 60 ft [20 m], 330 ft [100 m], 1/8 mile
[200 m], 1000 ft [300 m], and 1/4 mile [400 m]) and Acceleration Timers (0-60 mph [0-96 km/h] and
0-100 mph [0-160 km/h]) will be ready to acquire new
recent data measurements when the vehicle is at 0 mph
(0 km/h) and vehicle is in drive.
The timer listed shows the measured time required to
travel at the cited distance is met. Some timers will also
display speeds present at the time the distance was met.
 0-60 mph (0-100 km/h)
 0-100 mph (0-160 km/h)
 60 ft (20 m) ET
 330 ft (100 m) ET
 ⅛ Mile (200 m) + ET
 ⅛ Mile (200) + mph
 1000 ft (300 m) ET
 ¼ Mile (400 m) + ET
 ¼ Mile (400 m) + mph
 Brake Distance ft (meters)
NOTE:The distance measurement will be aborted if the brake
pedal is released or the parking brake is engaged, before
the vehicle comes to a complete stop.
Brake from mph (km/h)
NOTE:Brake Distance and Speed timers only display “ready”
when vehicle is traveling at a speed greater than 30 mph
(48 km/h).

OFF-ROAD PAGES — IF EQUIPPED
Your vehicle may be equipped with Off-Road Pages which
display vehicle information related to the drivetrain,
transfer case, and coolant/oil gauges. To access Off-Road Pages, press the Vehicle button on the
touchscreen, select the Offroad tab, and then select the
OFF ROAD button on the main screen. Off-Road Pages can
also be accessed through the app drawer.

(Continued)
Lights
Have someone observe the operation of brake lights and
exterior lights while you work the controls. Check turn
signal and high beam indicator lights on the instrument
panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight parking for
fuel, coolant, oil, or other fluid leaks. Also, if gasoline
fumes are detected or if fuel or brake fluid leaks are
suspected, the cause should be located and corrected
immediately.
EXHAUST GAS
The best protection against carbon monoxide entry into
the vehicle body is a properly maintained engine exhaust
system.
Whenever a change is noticed in the sound of the exhaust
system, when exhaust fumes can be detected inside the
vehicle, or when the underside or rear of the vehicle is
damaged, have an authorized dealer inspect the complete
exhaust system and adjacent body areas for broken,
damaged, deteriorated, or mispositioned parts. Open
seams or loose connections could permit exhaust fumes
to seep into the passenger compartment. In addition,
inspect the exhaust system each time the vehicle is raised
for lubrication or oil change. Replace as required.
CARBON MONOXIDE WARNINGS
WARNING!
Exhaust gases can injure or kill. They contain carbon
monoxide (CO), which is colorless and odorless.
Breathing it can make you unconscious and can
eventually poison you. To avoid breathing (CO), follow
these safety tips:
Do not run the engine in a closed garage or in
confined areas any longer than needed to move your
vehicle in or out of the area.
If you are required to drive with the trunk/liftgate/
rear doors open, make sure that all windows are
closed and the climate control BLOWER switch is set
at high speed. DO NOT use the recirculation mode.
 If it is necessary to sit in a parked vehicle with the
engine running, adjust your heating or cooling
controls to force outside air into the vehicle. Set the
blower at high speed.
WARNING!
WARNING!
Carbon monoxide (CO) in exhaust gases is deadly.
Follow the precautions below to prevent carbon
monoxide poisoning:
Do not inhale exhaust gases. They contain carbon
monoxide, a colorless and odorless gas, which can
kill. Never run the engine in a closed area, such as a
garage, and never sit in a parked vehicle with the
engine running for an extended period. If the vehicle
is stopped in an open area with the engine running
for more than a short period, adjust the ventilation
system to force fresh, outside air into the vehicle.
 Guard against carbon monoxide with proper mainte -
nance. Have the exhaust system inspected every
time the vehicle is raised. Have any abnormal condi -
tions repaired promptly. Until repaired, drive with all
side windows fully open.

IN CASE OF EMERGENCY327
(Continued)

Fuel Funnel Location

NOTE:
In certain cold conditions, ice may prevent the fuel door
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.
Emergency Gas Can Refueling:
Most gas cans will not open the flapper doors. A funnel is
provided to allow emergency refueling with a gas can.
See the following steps for refueling:

1. Retrieve funnel from under the passenger’s front seat.

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

Inserting Funnel

3. Ensure funnel is inserted fully to hold flapper doors open.
4. Pour fuel into funnel opening.
5. Remove funnel from filler pipe, clean off prior to putting back in the spare tire storage area.IF YOUR ENGINE OVERHEATS
If the vehicle is overheating, it will need to be serviced by
an authorized dealer.
Potential signs of vehicle overheating:
Temperature gauge is at HOT (H)
 Strong smell of coolant
 White smoke coming from engine or exhaust
 Coolant bottle coolant has bubbles present
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 Malfunction 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.
WARNING!
You or others can be badly burned by hot engine
coolant (antifreeze) or steam from your radiator. If you
see or hear steam coming from under the hood, do not
open the hood until the radiator has had time to cool.
Never try to open a cooling system pressure cap when
the radiator or coolant bottle is hot.
WARNING!

SERVICING AND MAINTENANCE
SCHEDULED SERVICING
Your vehicle is equipped with an automatic oil change
indicator system. The oil change indicator system will
remind you that it is time to take your vehicle in for
scheduled maintenance.
Based on engine operation conditions, the oil change
indicator message will illuminate. This means that service
is required for your vehicle. Operating conditions such as
frequent short-trips, trailer tow, and extremely hot or cold
ambient temperatures will influence when the “Oil Change
Required” message is displayed. Have your vehicle
serviced as soon as possible, within the next 500 miles
(805 km).An authorized dealer will reset the oil change indicator
message after completing the scheduled oil change. If a
scheduled oil change is performed by someone other than
an authorized dealer, the message can be reset by
referring to the steps described under Instrument Cluster
Display
Úpage 98.
NOTE:Under no circumstances should oil change intervals
exceed 10,000 miles (16,000 km), 12 months or
350 hours of engine run time, whichever comes first.
The 350 hours of engine run or idle time is generally only
a concern for fleet customers.
Once A Month Or Before A Long Trip:

Check engine oil level.
 Check windshield washer fluid level.
 Check tire pressure and look for unusual wear or
damage. Rotate tires at the first sign of irregular
wear, even if it occurs before the oil indicator system
turns on.
 Check the fluid levels of the coolant reservoir, brake
master cylinder, and fill as needed.
 Check function of all interior and exterior lights.
