Left and Right Information Group
Information that appears depends on current
gauge view and on-demand settings. See
General Information (page 116).
Fuel Gauge
The fuel gauge indicates about how much
fuel is 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.
Note:
The fuel gauge may vary slightly when
your vehicle is moving or on a slope.

A low fuel level reminder displays and
sounds when the distance to empty reaches
75 mi (120 km) to empty for MyKey, and at
50 mi (80 km), 25 mi (40 km), 10 mi (20 km)
and 0 mi (0 km) for all vehicle keys.
Note: The low fuel reminder can appear at
different fuel gauge positions depending on
fuel economy conditions. This variation is
normal. Engine Coolant Temperature Gauge WARNING:
Do not remove the
coolant reservoir cap when the engine is
on or 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.

normal range, stop your vehicle as soon as
safely possible, switch off the engine and let
the engine cool.
WARNING LAMPS AND
INDICATORS
The following warning lamps and indicators
alert you to a vehicle condition that may
become serious. Some lamps illuminate

adaptive steering system is off. It is possible
that the steering wheel may not be straight
when the vehicle is driving straight ahead. If

verified. Do not drive the vehicle and contact
an authorized dealer immediately.
See

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, 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) WARNING:
Failure to follow engine
block heater instructions could result in
property damage or serious personal
injury. WARNING:
Do not use your heater
with ungrounded electrical systems or
two-pronged adapters. There is a risk of
electrical shock. WARNING:
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. We recommend that you do the following for
a safe and correct operation:
•
Use a 16-gauge outdoor extension cord
that is product certified by Underwriter’ s
Laboratory (UL) or Canadian Standards
Association (CSA). This extension cord
must be suitable for use outdoors, in cold
temperatures, and be clearly marked
Suitable for Use with Outdoor
Appliances. Do not use an indoor
extension cord outdoors. This could
result in an electric shock or become a
fire hazard.
• Use as short an extension cord as
possible.
• Do not use multiple extension cords.
• Make sure that when in operation, the
extension cord plug and heater cord plug
connections are free and clear of water.
This could cause an electric shock or fire.
• Make sure your vehicle is parked in a
clean area, clear of combustibles.
• Make sure the heater, heater cord and
extension cord are firmly connected.
