Engine Coolant Temperature
Gauge
WARNING
Do not remove the coolant reservoir
cap when the cooling system is hot.
Wait 10 minutes for the cooling
system to cool down. Cover the coolant
reservoir cap with a thick cloth to prevent
the possibility of scalding and slowly
remove the cap. Failure to follow this
instruction could result in personal injury. Indicates engine coolant temperature. At
normal operating temperature, the level
indicator will be in the normal range. If the
engine coolant temperature exceeds the
normal range, stop your vehicle as soon as
safely possible, switch off the engine and
let the engine cool.
Fuel Gauge
Note:
The fuel gauge may vary slightly
when your vehicle is moving or on a gradient.
Switch the ignition on. The fuel gauge will
indicate approximately how much fuel is
left in the fuel tank. The arrow adjacent to
the fuel pump symbol indicates on which
side of your vehicle the fuel filler door is
located. The needle should move toward F when
you refuel your vehicle. If the needle points
to E after adding fuel, this indicates your
vehicle needs service soon.
After refueling some variability in needle
position is normal:
•
It may take a short time for the needle
to reach F after leaving the gas station.
This is normal and depends upon the
slope of pavement at the gas station.
• The fuel amount dispensed into the
tank is a little less or more than the
gauge indicated. This is normal and
depends upon the slope of pavement
at the gas station.
• If the gas station nozzle shuts off
before the tank is full, try a different
gas pump nozzle.
Low Fuel Reminder
A low fuel reminder triggers when the
distance to empty value reaches 50 mi
(80 km) to empty, with additional
warnings at 25 mi (40 km), 10 mi (20 km)
and 0 mi (0 km) to empty, provided the
message is cleared each time. An
additional warning at
75 mi (120 km) to
empty is provided when the MyKey is being
used.
Variations:
Note: The distance-to-empty warning can appear at different fuel gauge positions depending
on fuel economy conditions. This variation is normal. Fuel gauge position

running or when you are driving,
this indicates a malfunction.
Stop your vehicle as soon as it is safe to
do so and switch the engine off. Check the
engine oil level.
See
Engine Oil Check (page 333).

drive high is engaged. If the light
fails to display when the ignition
is turned on, or remains on, have the
system serviced immediately by your
authorized dealer.
Diesel Engine Brake

(page
225). Illuminates when you switch the
automatic engine brake on. See
General Information
(page
225).

illuminates when the DEF is
contaminated, low or someone
has tampered with the DEF system. See
Selective Catalytic Reductant System
(page
198).
Wait To Start
(If Equipped) Illuminates when you switch the
ignition on as part of the
pre-start system. Wait until the
wait to start indicator turns off before
attempting to start vehicle. See
Starting
a Diesel Engine (page 178).
Water In Fuel
(If Equipped) WARNING
Do not drain the water-in-fuel
separator while the engine is running.
Failure to follow this warning may
result in fire, serious injury, death or
property damage. During refueling, it is possible for
you to pump
water-contaminated diesel fuel
into your fuel tank. Your vehicle ’s fuel
system is equipped with a fuel filter and
water separator to remove water from the
fuel. The water in fuel indicator lights when
the fuel and water separator has a
significant quantity of water in it and
requires immediate draining.
If the water in fuel indicator illuminates
when the engine is running, stop your
vehicle as soon as safely possible, shut off
the engine, then drain the fuel and water
separator. See
Fuel Quality (page 187).
Allowing water to stay in the fuel system,
after the water in fuel indicator illuminates,
could result in extensive damage or failure
of the fuel injection system.
Note: Do not drain the fuel and water
separator while the engine is running. Air will
enter into the fuel system causing the engine
not to operate properly.

Cold Weather Starting (Flexible
Fuel Vehicles Only)
The starting characteristics of all grades
of E85 ethanol make it unsuitable for use
when ambient temperatures fall below
0°F (-18°C). Consult your fuel distributor
for the availability of winter grade ethanol.
As the outside temperature approaches
freezing, ethanol fuel distributors should
supply winter grade ethanol, the same as
with unleaded gasoline.
If summer grade ethanol is used in cold
weather conditions, 0°F (-18°C), you may
experience increased cranking times, rough
idle or hesitation until the engine has
warmed up.
You may experience a decrease in
performance when the engine is cold when
operating on E85 ethanol.
Do not use starting fluid such as ether in
the air intake system. Such fluid could
cause immediate explosive damage to the
engine and possible personal injury.
If you should experience cold weather
starting problems on E85 ethanol, and
neither an alternative brand of E85 ethanol
nor an engine block heater is available, the
addition of unleaded gasoline to your tank
improves cold starting performance. Your
vehicle is designed to operate on E85
ethanol alone, unleaded gasoline alone, or
any mixture of the two.
If the Engine Fails to Start Using the
Preceding Instructions (Flexible Fuel
Vehicles Only)
1. Press the accelerator pedal down one-third to one-half of its travel, and
then crank the engine.
2. When the engine starts, release the key, then gradually release the
accelerator pedal as the engine speed
increases. If the engine still does not
start, repeat Step 1. Guarding Against Exhaust Fumes WARNING
Exhaust leaks may result in entry of
harmful and potentially lethal fumes
into the passenger compartment. If
you smell exhaust fumes inside your
vehicle, have your vehicle inspected
immediately. Do not drive if you smell
exhaust fumes. Important Ventilating Information
If you stop your vehicle and then leave the
engine idling for long periods of time, we
recommend that you do one of the
following:
•
Open the windows at least 1 inch (2.5
centimeters).
• Set your climate control to outside air.
STARTING A DIESEL ENGINE -
6.7L DIESEL
Read all starting instructions carefully
before you start your vehicle.
For temperatures below
32°F (0°C), the
use of the correct grade engine oil is
essential for proper operation. Refer to
engine oil specifications for more
information. See
Capacities and
Specifications (page 432).
Your vehicle may have a cold weather
starting strategy that prevents severe
engine damage by assisting in engine
lubrication warm-up. In extremely cold
ambient temperatures, this strategy
activates and prevents the accelerator
pedal from being used for 30 seconds after
you start your vehicle. A message appears
in the information display as your vehicle
warms up. By not allowing the accelerator
pedal to be used, the engine oil is allowed
to properly lubricate the bearings
