STARTING AND OPERATING101
(Continued)
4. If the engine fails to start after eight attempts,
allow the starter to cool for at least
10 minutes, then repeat the procedure.
IF ENGINE FAILS TO START
If the engine fails to start after you have followed
the “Normal Starting” procedure and the vehicle
has not experienced an extended park condition
as defined previously, it may be flooded. Push the
accelerator pedal all the way to the floor and hold
it there while the engine is cranking. This should
clear any excess fuel in case the engine is flooded.
The starter motor will engage automatically, run for
10 seconds, and then disengage. Once this occurs,
release the accelerator pedal and brake pedal,
wait 10 to 15 seconds, then repeat the “Normal
Starting” procedure.
COLD WEATHER OPERATION
(B
ELOW –22°F OR −30°C)
To ensure reliable starting at these temperatures,
use of an externally powered electric engine block
heater (available from an authorized dealer) is
recommended.
AFTER STARTING
The idle speed is controlled automatically, and it
will decrease as the engine warms up.
ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine
and drivetrain (transmission and axle) in your
vehicle.
Drive moderately during the first 300 miles
(500 km). After the initial 60 miles (100 km),
speeds up to 50 or 55 mph (80 or 90 km/h) are
desirable.
Brief full-throttle acceleration within the limits of
local traffic laws contributes to a good break-in.
Wide-open throttle acceleration in low gear can be
detrimental and should be avoided.
The engine oil installed in the engine at the factory
is a high-quality energy conserving type lubricant.
Oil changes should be consistent with anticipated
climate conditions under which vehicle operations
will occur. For the recommended viscosity and
quality grades see Ú page 307.
CAUTION!
To prevent damage to the starter, do not crank
continuously for more than 10 seconds at a
time. Wait 10 to 15 seconds before trying again.
WARNING!
Never pour fuel or other flammable liquid into
the throttle body air inlet opening in an
attempt to start the vehicle. This could result
in flash fire causing serious personal injury.
Do not attempt to push or tow your vehicle to
get it started. Vehicles equipped with an auto -
matic transmission cannot be started this
way. Unburned fuel could enter the catalytic
converter and once the engine has started,
ignite and damage the converter and vehicle.
If the vehicle has a discharged battery,
booster cables may be used to obtain a start
from a booster battery or the battery in
another vehicle. This type of start can be
dangerous if done improperly Ú page 239.
CAUTION!
To prevent damage to the starter, do not
continuously crank the engine for more than 10
seconds at a time. Wait 10 to 15 seconds before
trying again.
WARNING!
CAUTION!
Never use Non-Detergent Oil or Straight Mineral
Oil in the engine or damage may result.

102STARTING AND OPERATING
(Continued)
(Continued)
NOTE:A new engine may consume some oil during its first
few thousand miles (kilometers) of operation. This
should be considered a normal part of the break-in
and not interpreted as a problem. Please check
your oil level with the engine oil indicator often
during the break-in period. Add oil as required.
PARKING BRAKE
Before leaving the vehicle, make sure that the
parking brake is fully applied and place the gear
selector in the PARK (P) position.
The foot operated parking brake is located below
the lower left corner of the instrument panel. To
apply the parking brake, firmly push the parking
brake pedal fully. To release the parking brake,
press the parking brake pedal a second time and
let your foot up as you feel the brake disengage.

Parking Brake
When the parking brake is applied with the ignition
switch in the ON/RUN position, the Brake Warning
Light in the instrument cluster will illuminate.
NOTE:
When the parking brake is applied and the
transmission is placed in gear, the Brake
Warning Light will flash. If vehicle speed is
detected, a chime will sound to alert the driver.
Fully release the parking brake before
attempting to move the vehicle.
This light only shows that the parking brake is
applied. It does not show the degree of brake
application.
When parking on a hill, it is important to turn the
front wheels toward the curb on a downhill grade
and away from the curb on an uphill grade. Apply
the parking brake before placing the gear selector
in PARK, otherwise the load on the transmission
locking mechanism may make it difficult to move
the gear selector out of PARK.
WARNING!
Never use the PARK position as a substitute
for the parking brake. Always apply the
parking brake fully when parked to guard
against vehicle movement and possible injury
or damage.
When leaving the vehicle, always remove the
key fob from the ignition and lock your vehicle.
Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Allowing chil -
dren to be in a vehicle unattended is
dangerous for a number of reasons. A child or
others could be seriously or fatally injured.
Children should be warned not to touch the
parking brake, brake pedal or the gear
selector.
When leaving the vehicle, always make sure
the keyless ignition node is in the OFF posi -
tion, remove the key fob from the vehicle and
lock the vehicle.
Do not leave the key fob in or near the vehicle
or in a location accessible to children, and do
not leave the ignition of a vehicle equipped
with Keyless Enter ‘n Go™ in the ACC or ON/
RUN position. A child could operate power
windows, other controls, or move the vehicle.
Be sure the parking brake is fully disengaged
before driving; failure to do so can lead to
brake failure and a collision.
WARNING!

112STARTING AND OPERATING
GUIDELINES FOR TRACK USE
NOTE:The standard Black Brembo Brake Pads are not
recommended for track use. Only the Red Brembo
Performance SRT brake pads are appropriate for
track use.
If your vehicle is equipped with Drive Modes,
they will alter the vehicle’s performance in
various driving situations. It is recommended
that your vehicle operates in SPORT or TRACK
modes during the track event.
Prior to each track event, verify all fluids are at
the correct levels.
Prior to each track event, verify the front and
rear brake pads have more than half pad thick -
ness remaining. If the brake pads require
changing, complete a brake burnish procedure
prior to track outing at full pace.
NOTE:Use of DOT 4 brake fluid is suggested for extended
track usage due to increased thermal capacity.
At the conclusion of each track event, it is
recommended that a brake bleed procedure is
performed to maintain the pedal feel and stop -
ping capability of your Brembo High Perfor -
mance brake system.
It is recommended that each track outing
should end with a minimum of one cooldown lap
using minimal braking.
It is recommended to check oil temperature
after each track session. If the oil is still above
225°F (107°C), do another cooldown lap if
possible, or keep the engine running and let idle
until below 225°F (107°C), in order to prevent
heat soaking of the engine. Ensure temperature
is reducing and do not leave vehicle gauges
unattended while idling just after a track
session.
It is recommended that the suspension system,
brake system, prop shaft, and half shaft boots
be checked for wear or damage after every track
event.
Track usage results in increased operating
temperatures of the engine, transmission, drive -
line and brake system. This may affect Noise
Vibration Harshness (NVH) countermeasures
designed into your vehicle. New components
may need to be installed to return the system to
the original NVH performance.
Tire pressure:
Recommended tire pressure of 33 psi
(230 kPa) when tires are cold, or below
42 psi (290 kPa) when hot.
NOTE:It is recommended that you target below 42 psi
(290 kPa) when tires are hot at the conclusion of
each track session. Starting at 33 psi (230 kPa)
cold and adjusting based on ambient and track
conditions is recommended. Tire pressure can be
monitored via the instrument cluster display and
can assist with adjustments.
Track burnishing your brakes
To avoid “green lining fade” during track use, the
brake pads and rotors must have a thermal
burnish for factory-installed components or when
new brake friction components are installed:

1. Use one track session to burnish brakes by driving at 75% speed. Brake at approximately
0.60 - 0.80g max without Anti-Lock Brake
System (ABS) intervention.

2. Complete one lap in this manner until you start smelling the brakes. Continue for another half
lap at speed, then complete a two lap
cooldown with minimal brake applications.
Ensure the brakes are not smoking. If they are,
complete another cooldown lap.
3. Getting the brakes to smoke is an indication that the brakes have overheated and may
negatively affect future track usage.

STARTING AND OPERATING151
Flowing Water
If the water is swift flowing and rising (as in storm
run-off), avoid crossing until the water level
recedes and/or the flow rate is reduced. If you
must cross flowing water avoid depths in excess of
9 inches (23 cm). The flowing water can erode the
streambed, causing your vehicle to sink into
deeper water. Determine exit point(s) that are
downstream of your entry point to allow for drifting.
Standing Water
Avoid driving in standing water deeper than
20 inches (51 cm), and reduce speed
appropriately to minimize wave effects. Maximum
speed in 20 inches (51 cm) of water is less than
5 mph (8 km/h).
Maintenance
After driving through deep water, inspect your
vehicle fluids and lubricants (engine oil,
transmission oil, axle, transfer case) to ensure the
fluids have not been contaminated. Contaminated
fluid (milky, foamy in appearance) should be
flushed/changed as soon as possible to prevent
component damage.
Driving In Snow, Mud And Sand
In heavy snow, when pulling a load, or for
additional control at slower speeds, shift the
transmission to a low gear and shift the transfer
case to AWD Low if necessary Ú page 108. Only
shift into a lower gear to maintain forward motion.
Over-revving the engine can spin the wheels and
traction will be lost.
Avoid abrupt downshifts on icy or slippery roads,
because engine braking may cause skidding and
loss of control.
Hill Climbing
NOTE:Before attempting to climb a hill, determine the
conditions at the crest and/or on the other side.
Before climbing a steep hill, shift the transmission
to a lower gear and shift the transfer case to AWD
Low. Use FIRST gear and AWD Low for very steep
hills. If you stall or begin to lose forward motion while
climbing a steep hill, allow your vehicle to come to
a stop and immediately apply the brakes. Restart
the engine, and shift into REVERSE. Back slowly
down the hill, allowing the compression braking of
the engine to help regulate the speed. If the brakes
are required to control vehicle speed, apply them
lightly and avoid locking or skidding the tires.
WARNING!
If the engine stalls, you lose forward motion, or
cannot make it to the top of a steep hill or grade,
never attempt to turn around. To do so may
result in tipping and rolling the vehicle. Always
back carefully straight down a hill in REVERSE
gear. Never back down a hill in NEUTRAL using
only the brake.4

228SAFETY
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/lift -
gate/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!
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
maintenance. Have the exhaust system
inspected every time the vehicle is raised.
Have any abnormal conditions repaired
promptly. Until repaired, drive with all side
windows fully open.

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, extremely hot or cold ambient
temperatures, and E85 fuel usage 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.
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 the tire pressure and look for unusual
wear or damage
Check the fluid levels of the coolant reservoir,
brake master cylinder and fill as needed
Check function of all interior and exterior lights
