If the light comes on and stays on, there is
a brake problem. Have the brake system
inspected right away. This light may come
on if the brake fluid is low. SeeBrake Fluid
0 256.
If the light comes on while driving, pull off
the road and stop carefully. The brake
system has electric brake boost. Vehicle
speed may be limited when the brake
system warning light comes on. The brake
pedal might be harder to push, or the brake
pedal may go closer to the floor. It could
take longer to stop. If the light is still on,
have the vehicle towed for service. See
Transporting a Disabled Vehicle 0301.
{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

Parking Brake system. A message may also
display in the Driver Information
Center (DIC).
If the light does not come on, or remains
flashing, see your dealer.

This light should come on briefly when the
vehicle is turned on. If it does not come on,
have it fixed so it will be ready to warn if
there is a problem.
If this light stays on or comes on while
driving, there is a problem with the Electric
Parking Brake (EPB). Take the vehicle to a
dealer as soon as possible. In addition to the
parking brake, other safety functions that
utilize the EPB may also be degraded.
A message may also display in the Driver
Information Center (DIC). See Electric Parking
Brake 0198.
Antilock Brake System (ABS)

176 Driving and Operating
{Warning
Drinking alcohol or taking drugs and then
driving is very dangerous. Your reflexes,
perceptions, attentiveness, and judgment
can be affected by even a small amount
of alcohol or drugs. You can have a
serious—or even fatal —collision if you
drive after drinking or taking drugs.
Do not drive while under the influence of
alcohol or drugs, or ride with a driver
who has been drinking or is impaired by
drugs. Find alternate transportation
home; or if you are with a group,
designate a driver who will remain sober.
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.
If the engine ever stops while the vehicle is
being driven, brake normally but do not
pump the brakes. Doing so could make the
pedal harder to push down. If the engine
stops, there will be some power brake assist
but it will be used when the brake is
applied. Once the power assist is used up, it
can take longer to stop and the brake pedal
will be harder to push.
Steering
Caution
To avoid damage to the steering system,
do not drive over curbs, parking barriers,
or similar objects at speeds greater than
3 km/h (1 mph). Use care when driving
(Continued)
Caution (Continued)
over other objects such as lane dividers
and speed bumps. Damage caused by
misuse of the vehicle is not covered by
the vehicle warranty.
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.

Driving and Operating 185
automatic transmission vehicle, and the
steering column, if equipped with a locking
steering column.
To turn off the vehicle:1. Make sure that the vehicle is stopped.
2. Shift to P (Park).
3. Push the key all the way in towards the steering column, then turn the key to
LOCK/OFF.
4. Remove the key.
5. Set the parking brake. See Electric
Parking Brake 0198.
See your dealer if the key can be removed
in any other position. Retained Accessory Power (RAP) will remain
active. See
Retained Accessory Power (RAP)
0 192.
A warning chime will sound when the driver
door is opened and the key is in the
ignition.
If equipped with a locking steering column,
the steering can bind with the front wheels
turned off center, which may prevent key
rotation out of LOCK/OFF. If this happens,
move the steering wheel from right to left
while turning the key to ACC/ACCESSORY.
If this does not work, then the vehicle needs
service.{Warning
Turning off the vehicle while moving may
cause loss of power assist in the brake
and steering systems and disable the
airbags. While driving, only shut the
vehicle off in an emergency.
In an emergency, if the vehicle cannot be
pulled over and must be turned off while
driving: 1. Push the key all the way in toward the steering column, then turn the key to
ACC/ACCESSORY. 2. Brake using firm and steady pressure. Do
not pump the brakes repeatedly. This
may deplete power assist, requiring
increased brake pedal force.
3. Shift the vehicle to N (Neutral). This can be done while the vehicle is moving.
Continue braking and steer the vehicle to
a safe location.
4. Come to a complete stop. Shift to P (Park). Push the key all the way in
toward the steering column, then turn
the ignition to LOCK/OFF.
5. Set the parking brake. See Electric
Parking Brake 0198.
Caution
Use the correct key, make sure it is all
the way in —or pushed all the way in
toward the steering column when turning
off the vehicle —and turn it only with
your hand.
1. (ACC/ACCESSORY) : This position allows
features such as the infotainment system
to operate while the vehicle is off. It also
unlocks the steering column, if equipped
with a locking steering column. Use
this position if the vehicle must be
pushed or towed. See Retained Accessory

not start. Move the steering wheel from left
to right while attempting to start the
vehicle. If this does not work, the vehicle
needs service.
If the vehicle must be shut off in an
emergency:1. Brake using a firm and steady pressure. Do not pump the brakes repeatedly. This
may deplete power assist, requiring
increased brake pedal force.
2. Shift the vehicle to N (Neutral). This can be done while the vehicle is moving.
After shifting to N (Neutral), firmly apply
the brakes and steer the vehicle to a
safe location.
3. Come to a complete stop. Hold the brake pedal down and shift to P (Park). The
vehicle must be in P (Park) to turn the
ignition off.
4. Continue to hold the brake pedal down.
5. Set the parking brake. See Electric
Parking Brake 0198.
6. Press ENGINE START/STOP once to turn the ignition off.
7. Release the brake pedal. If the vehicle cannot be pulled over, and
must be shut off while driving, press and
hold ENGINE START/STOP for longer than
two seconds, or press twice in five seconds.
Accessory (Amber Indicator Light) :
This
mode allows some electrical accessories to
be used when the engine is off.
With the ignition off, pressing the button
one time without the brake pedal applied
will place the ignition system in accessory.
The ignition will switch from accessory to
OFF after five minutes to prevent battery
rundown.
ON/RUN/START (Green Indicator Light) : This
mode is for driving and starting. With the
ignition off, and the brake pedal applied,
pressing the button once will turn the
ignition on. Once engine cranking begins,
release the button. Engine cranking will
continue until the engine starts. See Starting
the Engine 0187.
Service Mode
This power mode is available for service and
diagnostics, and to verify the proper
operation of the malfunction indicator lamp
as may be required for emission inspection
purposes. With the vehicle off, and the
brake pedal not applied, pressing and holding the button for more than
five seconds will place the vehicle in Service
Mode. The instruments and audio systems
