106 Instruments and Controls
Here are some things that owners
ask about. None of these show a
problem with the fuel gauge:
.At the service station, the fuel
pump shuts off before the gauge
reads full.
. It takes a little more or less fuel
to fill up than the gauge
indicated. For example, the
gauge may have indicated the
tank was half full, but it actually
took a little more or less than
half the tank's capacity to fill
the tank.
. The gauge takes a few seconds
to stabilize after the ignition is
turned on, and goes back to
empty when the ignition is
turned off.Driver Efficiency Gauge
This gauge appears on the left side
of the display in the Classic
Enhanced configuration.
This gauge is a guide to driving in
an efficient manner by keeping the
ball green and in the center of the
gauge. See
Driving for Better Energy
Efficiency 026.
accel : If the ball turns yellow and
travels above the center of the
gauge, acceleration is too
aggressive to optimize efficiency.
brake : If the ball turns yellow and
travels below the center of the
gauge, braking is too aggressive to
optimize efficiency.
In the Modern display
configurations, the light ring in the
center of the display acts as an
efficiency gauge. It is green when
driving efficiently and turns yellow
when acceleration or braking is too
aggressive.

not used to perform an Emissions
Inspection/Maintenance test or to
service the vehicle may affect
vehicle operation. SeeAdd-On
Electrical Equipment 0234. See
your dealer if assistance is needed.
The vehicle may not pass
inspection if:
. The light is on when the engine
is running.
. The light does not come on
when the vehicle is in Service
Only Mode.
. Critical emission control systems
have not been completely
diagnosed. If this happens, the
vehicle would not be ready for
inspection and might require
several days of routine driving
before the system is ready for
inspection. This can happen if
the 12-volt battery has recently
been replaced or run down, or if
the vehicle has been recently
serviced.
See your dealer if the vehicle will
not pass or cannot be made ready
for the test.Brake System Warning
Light
The vehicle brake system consists
of two hydraulic circuits. If one
circuit is not working, the remaining
circuit can still work to stop the
vehicle. For normal braking
performance, both circuits need to
be working.
If the warning light comes on, there
is a brake problem. Have the brake
system inspected right away.
MetricEnglish
This light should come on briefly
when the engine is started. If it does
not come on then, have it fixed so it
will be ready to warn you if there is
a problem.
If the light comes on and stays on,
there is a brake problem.
{Warning
The brake system might not be
working properly if the brake
system warning light is on.
Driving with the brake system
warning light on can lead to a
crash. If the light is still on after
the vehicle has been pulled off
the road and carefully stopped,
have the vehicle towed for
service.
Electric Parking Brake
Light
MetricEnglish
This light comes on when the
parking brake is applied. If the light
continues flashing after the parking
brake is released, or while driving,
there is a problem with the Electric

112 Instruments and Controls

system. A message may also
display in the Driver Information
Center (DIC). SeeBrake System
Messages 0133.
If the light does not come on,
or remains flashing, see your dealer.
Service Electric Parking
Brake Light
If this light comes on and stays on,
there is a problem with a system on
the vehicle that is causing the
parking brake system to work at a
reduced level. The vehicle can still
be driven, but should be taken to a
dealer as soon as possible. See
Electric Parking Brake 0188. If a
message displays in the Driver
Information Center (DIC), see Brake
System Messages 0133.
Antilock Brake System
(ABS) Warning Light
This light should come on briefly
when the vehicle is in ON/RUN. If it
does not come on, have the vehicle
serviced by your dealer.
If the ABS warning light stays on
longer than a few seconds after the
vehicle is in ON/RUN, or comes on
and stays on while driving, try
resetting the system. To reset the
system:
1. While driving, pull over when it is safe to do so.
2. Place the vehicle in P (Park).
3. Turn the vehicle off.
4. Restart the vehicle.
If the ABS warning light remains on
after resetting the system or comes
on again while driving, the vehicle needs service. If the ABS warning
light is on, but the regular brake
system warning light is not on, the
antilock brakes are not working
properly, but the regular brakes are
still functioning. Have the vehicle
serviced right away. If both brake
lights are on, the vehicle does not
have antilock brakes, and there is a
problem with the regular brakes as
well. Have the vehicle towed for
service. See
Towing the
Vehicle 0311.
Sport Mode Light
This light comes on when Sport
Mode is selected. See “Sport Mode”
in Driver Selected Operating Modes
0 181 for more information.

166 Driving and Operating
Refer to the separate Infotainment
system manual for more information
on using that system, including
pairing and using a cell phone.
If equipped, refer to the navigation
manual for information on that
system, including pairing and using
a cell phone.
Defensive Driving
Defensive driving means“always
expect the unexpected.” The first
step in driving defensively is to wear
the safety belt. See Safety
Belts 057.
. Assume that other road users
(pedestrians, bicyclists, and
other drivers) are going to be
careless and make mistakes.
Anticipate what they might do
and be ready.
. Allow enough following distance
between you and the driver in
front of you.
. Focus on the task of driving.
Drunk Driving
Death and injury associated with
drinking and driving is a global
tragedy.
{Warning
Drinking and then driving is very
dangerous. Your reflexes,
perceptions, attentiveness, and
judgment can be affected by even
a small amount of alcohol. You
can have a serious —or even
fatal —collision if you drive after
drinking.
Do not drink and drive or ride with
a driver who has been drinking.
Ride home in a cab; or if you are
with a group, designate a driver
who will not drink.
Control of a Vehicle
Braking, steering, and accelerating
are important factors in helping to
control a vehicle while driving.
Braking
Braking action involves perception
time and reaction time. Deciding to
push the brake pedal is perception
time. Actually doing it is
reaction time.
Average driver reaction time is
about three-quarters of a second. In
that time, a vehicle moving at
100 km/h (60 mph) travels 20 m
(66 ft), which could be a lot of
distance in an emergency.
Helpful braking tips to keep in mind
include:
. Keep enough distance between
you and the vehicle in front
of you.
. Avoid needless heavy braking.
. Keep pace with traffic.
Power brake assist is available
unless the 12-volt battery drains or
there is a fault in the brake
computer.

Driving and Operating 167
Steering
Electric Power Steering
The vehicle has electric power
steering. It does not have power
steering fluid. Regular maintenance
is not required.
If power steering assist is lost due
to a system malfunction, the vehicle
can be steered, but may require
increased effort.
See your dealer if there is a
problem.
If the steering wheel is turned until it
reaches the end of its travel and is
held against that position for an
extended period of time, power
steering assist may be reduced.
If the steering assist is used for an
extended period of time, power
assist may be reduced.
Normal use of the power steering
assist should return when the
system cools down.
See specific vehicle steering
messages underService Vehicle
Messages 0139. See your dealer if
there is a problem.
Curve Tips
. Take curves at a reasonable
speed.
. Reduce speed before entering a
curve.
. Maintain a reasonable steady
speed through the curve.
. Wait until the vehicle is out of
the curve before accelerating
gently into the straightaway.
Steering in Emergencies
.There are some situations when
steering around a problem may
be more effective than braking.
. Holding both sides of the
steering wheel allows you to turn
180 degrees without removing
a hand.
. The Antilock Brake System
(ABS) allows steering while
braking.
Off-Road Recovery
The vehicle's right wheels can drop
off the edge of a road onto the
shoulder while driving. Follow
these tips:
1. Ease off the accelerator and then, if there is nothing in the
way, steer the vehicle so that it
straddles the edge of the
pavement.
2. Turn the steering wheel about one-eighth of a turn, until the
right front tire contacts the
pavement edge.
