XXX mi (km) to empty
Shows approximate fuel level before the
fuel tank reaches empty. The value is
dynamic and can change (raise or lower)
depending on driving style.
Fuel gauge
Switch the ignition on. The fuel gauge will
indicate approximately how much fuel is
in the fuel tank. The arrow next to the fuel
pump symbol shows the fuel filler door
side of your vehicle. When the fuel level
becomes low, the level indicator will
change to amber. When the fuel level
becomes critically low, the level indicator
will change to red.
Note: The fuel gauge level may vary slightly
when your vehicle is moving or when driving
on a slope.
Note: When a MyKey® is in use, low fuel
warnings will display earlier. Round tachometer
Indicates the engine speed in revolutions
per minute. Driving with your tachometer
pointer continuously at the top of the scale
may damage the engine. During SelectShift
Automatic
™ transmission (SST) use, the
currently selected gear will appear in the
display.
Engine coolant temperature gauge
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.

Stopping the Engine When Your
Vehicle is Moving
WARNING
Switching off the engine when the
vehicle is still moving will result in a
loss of brake and steering assistance.
The steering will not lock, but higher effort
will be required. When the ignition is
switched off, some electrical circuits,
including air bags, warning lamps and
indicators may also be off. If the ignition
was turned off accidentally, you can shift
into neutral (N) and re-start the engine. Vehicles with an Ignition Key
1.
Shift into neutral and use the brakes to
bring your vehicle to a safe stop.
2. When your vehicle has stopped, shift into park (P) and switch the ignition
off.
3. Apply the parking brake.
Vehicles with Keyless Start
1. Shift into neutral and use the brakes to
bring your vehicle to a safe stop.
2. When your vehicle has stopped, shift into park (P).
3. Press and hold the push button ignition
switch, or press it three times within
two seconds.
4. Apply the parking brake.
Guarding Against Exhaust Fumes WARNING
If you smell exhaust fumes inside
your vehicle, have your vehicle
checked by your authorized dealer
immediately. Do not drive your vehicle if
you smell exhaust fumes. Carbon
monoxide is present in exhaust fumes.
Take precautions to avoid its dangerous
effects. Important Ventilating Information
If you stop your vehicle and then leave the
engine idling for long periods, we
recommend that you do one of the
following:
•
Open the windows at least 1 in (3 cm).
• Set your climate control to outside air.
ENGINE BLOCK HEATER (If
Equipped) WARNINGS
Failure to follow engine block heater
instructions could result in property
damage or serious personal injury.
Do not use your heater with
ungrounded electrical systems or
two-pronged adapters. There is a risk
of electrical shock. Do not fully close the hood, or allow
it to drop under its own weight when
using the engine block heater. This
could damage the power cable and may
cause an electrical short resulting in fire,
injury and property damage. Note:
The heater is most effective when
outdoor temperatures are below 0°F
(-18°C).
The heater acts as a starting aid by
warming the engine coolant. This allows
the climate control system to respond
quickly. The equipment includes a heater
element (installed in the engine block) and
a wire harness. You can connect the
system to a grounded 120-volt AC
electrical source.
