Disposal Of Used Engine Coolant
Used ethylene glycol-based engine coolant (antifreeze) is a
regulated substance requiring proper disposal. Check with
your local authorities to determine the disposal rules for
your community. To prevent ingestion by animals or
children, do not store ethylene glycol-based engine coolant
(antifreeze) in open containers or allow it to remain in
puddles on the ground. If ingested by a child or pet, seek
emergency assistance immediately. Clean up any ground
spills immediately.
Points To Remember
NOTE:When the vehicle is stopped after a few miles/
kilometers of operation, you may observe vapor coming
from the front of the engine compartment. This is normally
a result of moisture from rain, snow, or high humidity
accumulating on the radiator and being vaporized when
the thermostat opens, allowing hot engine coolant (anti-
freeze) to enter the radiator.
If an examination of your engine compartment shows no
evidence of radiator or hose leaks, the vehicle may be
safely driven. The vapor will soon dissipate.
• Do not overfill the coolant expansion bottle. •
Check the coolant freeze point in the radiator and in the
coolant expansion bottle. If engine coolant (antifreeze)
needs to be added, the contents of the coolant expansion
bottle must also be protected against freezing.
• If frequent engine coolant (antifreeze) additions are
required, the cooling system should be pressure tested
for leaks.
• Maintain engine coolant (antifreeze) concentration at a
minimum of 50% OAT coolant (conforming to
MS.90032) and distilled water for proper corrosion pro-
tection of your engine which contains aluminum com-
ponents.
• Make sure that the coolant expansion bottle overflow
hoses are not kinked or obstructed.
• Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean.
• Do not change the thermostat for Summer or Winter
operation. If replacement is ever necessary, install ONLY
the correct type thermostat. Other designs may result in
unsatisfactory engine coolant (antifreeze) performance,
poor gas mileage, and increased emissions.

Charge Air Cooler — Inter-Cooler
The charge air cooler is positioned in front of the radiator
and the air conditioner condenser. Air enters the engine
through the air cleaner and passes through the turbo-
charger, where it is pressurized. This pressurized air rap-
idly reaches high temperature. The air is then directed
through a hose to the charge air cooler and through another
hose to the intake manifold of the engine. This cooling
process enables more efficient burning of fuel resulting in
fewer emissions.
To guarantee optimum performance of the system, keep
the surfaces of the charge air cooler, condenser and radiator
clean and free of debris. Periodically check the hoses
leading to and from the charge air cooler for cracks or loose
clamps resulting in loss of pressure and reduced engine
performance.
Brake System
Brake Master Cylinder — Brake Fluid Level Check
The fluid level of the master cylinder should be checked
when performing under the hood service, or immediately
if the “Brake System Warning Light” indicates system
failure.The brake master cylinder has a translucent plastic reser-
voir. On the outboard side of the reservoir, there is a
“MAX” mark and a “MIN” mark. The fluid level must be
kept within these two marks. Do not add fluid above the
full mark because leakage may occur at the cap.
With disc brakes, the fluid level can be expected to fall as
the brake linings wear. However, an unexpected drop in
fluid level may be caused by a leak and a system check
should be conducted.
Refer to “Fluids, Lubricants, And Genuine Parts” in “Main-
taining Your Vehicle” for further information.
WARNING!
•
Use only manufacturer’s recommended brake fluid.
Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further information.
Using the wrong type of brake fluid can severely
damage your brake system and/or impair its perfor-
mance. The proper type of brake fluid for your
vehicle is also identified on the original factory
installed hydraulic master cylinder reservoir.

Required Maintenance
Refer to the Maintenance Schedules on the following pages
for required maintenance.
At Every Oil Change Interval As Indicated By OilChange Indicator System:
•Change oil and filter.
• Completely fill the Diesel Exhaust Fluid tank.
• Drain water from fuel filter assembly.
• Rotate the tires. Rotate at the first sign of irregular
wear, even if it occurs before the oil indicator
system turns on.
• Inspect battery and clean and tighten terminals as
required.
At Every Oil Change Interval As Indicated By Oil
Change Indicator System:
•Inspect brake pads, shoes, rotors, drums, hoses and
park brake.
• Inspect engine cooling system protection and hoses.
• Inspect exhaust system.
• Inspect engine air cleaner if using in dusty or
off-road conditions.

REMOTE STARTING SYSTEM — IF EQUIPPED
This system uses the key fob to start the engine
conveniently from outside the vehicle while still
maintaining security. The system has a range of
approximately 300 ft (91 m).
NOTE:
• The vehicle must be equipped with an automatic trans-
mission to be equipped with Remote Start.
• The Remote Start system will wait for the “Wait To Start”
telltale to extinguish before cranking the engine. This
allows time for the intake heater to pre-heat the incom-
ing air, and is normal operation in cold weather. Refer to
“Wait To Start” located in “Warning and Indicator
Lights” within “Understanding Your Instrument Panel”.
How To Use Remote Start
All of the following conditions must be met before the
engine will remote start:
• Transmission in PARK
• Doors closed
• Hood closed •
HAZARD switch off
• BRAKE switch inactive (brake pedal not pushed)
• Ignition key removed from ignition switch
• Battery at an acceptable charge level
• PANIC button not pushed
• Fuel meets minimum requirement
• Water In Fuel Indicator Light is not illuminated
• Wait To Start Light is not illuminated
WARNING!
•Do not start or run an engine in a closed garage or
confined area. Exhaust gas contains Carbon Monox-
ide (CO) which is odorless and colorless. Carbon
Monoxide is poisonous and can cause serious injury
or death when inhaled.
• Keep Remote Keyless Entry key fobs away from
children. Operation of the Remote Start System,
windows, door locks or other controls could cause
serious injury or death.
92 THINGS TO KNOW BEFORE STARTING YOUR VEHICLE

3. Speedometer•Indicates vehicle speed.
4. Fuel Gauge •The pointer shows the level of fuel in the fuel tank
when the ignition switch is in the ON/RUN position.
•
The fuel pump symbol points to the side of the
vehicle where the fuel filler door is located.
5. DEF Gauge •The DEF Gauge displays the actual level of Diesel
Exhaust Fluid in the DEF tank. Diesel Exhaust Fluid
(DEF) is required to maintain normal vehicle operation
and emissions compliance. If something is wrong with
the gauge, a DEF Warning Message or Malfunction
Indicator Light (MIL) will be displayed. More infor-
mation is available in the Instrument Cluster Display
section under the heading of Diesel Exhaust Fluid
(DEF) Warning Messages.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling
coolant. You may want to call an authorized dealer for

service if your vehicle overheats. If you decide to look
under the hood yourself, see “Maintaining Your Ve-
hicle.” Follow the warnings under the “Cooling Sys-
tem Pressure Cap” paragraph.
CAUTION!
Driving with a hot engine cooling system could dam-
age your vehicle. If the temperature gauge reads “H”
pull over and stop the vehicle. Idle the vehicle with the
air conditioner turned off until the pointer drops back
into the normal range. If the pointer remains on the
“H”, turn the engine off immediately and call an
authorized dealer for service.
NOTE:
• The gauge may take up to five seconds to update after
adding a gallon or more of Diesel Exhaust Fluid (DEF) to
the DEF tank. If you have a fault related to the DEF
system, the gauge may not update to the new level. See
your authorized dealer for service.

1. Tachometer•Indicates the engine speed in revolutions per minute
(RPM x 1000).
2. Engine Coolant Temperature •This gauge shows the engine coolant temperature. The
gauge pointer will likely show higher temperatures
when driving in hot weather, up mountain grades, or
in heavy stop and go traffic. If the red Warning Light
turns on while driving, safely bring the vehicle to a
stop, and turn off the engine. DO NOT operate the
vehicle until the cause is corrected.
