If this occurs, try activating ACC again later, following a
key cycle. If the problem persists, see your authorized
dealer.
Precautions While Driving With ACC
In certain driving situations, ACC may have detection
issues. In these cases, ACC may brake late or unexpect-
edly. The driver needs to stay alert and may need to
intervene.
Towing A Trailer
NOTE:Towing a trailer is not advised when using ACC.
Offset Driving
ACC may not detect a vehicle in the same lane that is
offset from your direct line of travel, or a vehicle merging
in from a side lane. There may not be sufficient distance
to the vehicle ahead. The offset vehicle may move in and
out of the line of travel, which can cause your vehicle to
brake or accelerate unexpectedly.
Turns And Bends
When driving on a curve with ACC engaged, the system
may decrease the vehicle speed and acceleration for
stability reasons, with no target vehicle detected. Once

INSTRUMENT CLUSTER DESCRIPTIONS
1. Tachometer
The red segments indicate the maximum permissible
engine revolutions per minute (RPM x 1000) for each gear
range. Ease up on the accelerator before reaching the red
area.
2. Malfunction Indicator Light (MIL)
The Malfunction Indicator Light (MIL) is part of
an onboard diagnostic system called OBD. The
OBD system monitors engine and automatic
transmission control systems. The MIL will turn on when
the ignition is in the ON/RUN position before engine
start. If the MIL does not come on when turning the key
from OFF to ON/RUN, have the condition checked
promptly.
Certain conditions, such as a loose or missing gas cap,
poor fuel quality, etc., may illuminate the MIL after
engine start. The vehicle should be serviced if the MIL
stays on through several of your typical driving cycles. In
most situations, the vehicle will drive normally and will
not require towing.
CAUTION!
Prolonged driving with the Malfunction Indicator
Light (MIL) on could cause damage to the engine
control system. It also could affect fuel economy and
driveability. If the MIL is flashing, severe catalytic
converter damage and power loss will soon occur.
Immediate service is required.
WARNING!
A malfunctioning catalytic converter, as referenced
above, can reach higher temperatures than in normal

The gauge pointer will likely indicate a higher tempera-
ture when driving in hot weather, up mountain grades,
or when towing a trailer. It should not be allowed to
exceed the upper limits of the normal operating range.
CAUTION!
Driving with a hot engine cooling system could
damage your vehicle. If the temperature gauge reads
“H,” pull over and stop the vehicle. Idle the vehicle
with the air conditioner turned off until the pointer
drops back into the normal range. If the pointer
remains on the “H,” and you hear a chime, turn the
engine OFF immediately and call for service.
WARNING!
A hot engine cooling system is dangerous. You or
others could be badly burned by steam or boiling

coolant. You may want to call a service center if your
vehicle overheats. If you decide to look under the
hood yourself, refer to “Maintaining Your Vehicle”
and follow the warnings under the Cooling System
Pressure Cap paragraph.
17. Tire Pressure Monitoring Telltale Light
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recommended
by the vehicle manufacturer on the vehicle
placard or tire inflation pressure label. (If your vehicle
has tires of a different size than the size indicated on the
vehicle placard or tire inflation pressure label, you should
determine the proper tire inflation pressure for those
tires.)

Sync feature On/Off. The Sync indicator is illuminated
when this feature is enabled. Sync is used to synchronize
the passenger temperature setting with the driver tem-
perature setting. Changing the passenger temperature
setting while in Sync will automatically exit this feature.
10. Blower Control
Blower control is used to regulate the amount of air
forced through the climate system. There are seven
blower speeds available. Adjusting the blower will cause
automatic mode to switch to manual operation. The
speeds can be selected using either the blower control
knob on the faceplate or the buttons on the touchscreen
as follows:

346 STARTING AND OPERATING

Press the clutch pedal fully to the floor, and cycle the
ignition switch to the START position and release when
the engine starts. If the engine fails to start within 15
seconds, place the ignition in the OFF position, wait 10 to
15 seconds, then repeat the “Normal Starting” procedure.
WARNING!
Do not attempt to push or tow your vehicle to get it
started. Unburned fuel could enter the catalytic con-
verter and once the engine has started, ignite and
damage the converter and vehicle. If the vehicle has
a discharged battery, booster cables may be used to
obtain a start from another vehicle. This type of start
can be dangerous if done improperly, so follow the
procedure carefully. Refer to “Jump Starting” in
“What To Do In Emergencies” for further informa-
tion.
Automatic Transmission — If Equipped
The shift lever must be in the NEUTRAL or PARK
position before you can start the engine. Apply the brakes
before shifting into any driving gear.
CAUTION!
Damage to the transmission may occur if the follow-
ing precautions are not observed:
•Do not shift from REVERSE, PARK, or NEUTRAL
into any forward gear when the engine is above
idle speed.
•Shift into PARK only after the vehicle has come to
a complete stop.
•Shift into or out of REVERSE only after the vehicle
has come to a complete stop and the engine is at
idle speed.
•Before shifting into any gear, make sure your foot
is firmly on the brake pedal.
348 STARTING AND OPERATING

WARNING!(Continued)
•Do not attempt to push or tow your vehicle to get it
started. Vehicles equipped with an automatic trans-
mission cannot be started this way. Unburned fuel
could enter the catalytic converter and once the
engine has started, ignite and damage the converter
and vehicle.
•If the vehicle has a discharged battery, booster
cables may be used to obtain a start from a booster
battery or the battery in another vehicle. This type
of start can be dangerous if done improperly. Refer
to “Jump Starting” in “What To Do In Emergen-
cies” for further information.
Clearing A Flooded Engine (Using ENGINE
START/STOP Button) — Automatic Transmission
Only
If the engine fails to start after you have followed the
“Normal Starting” or “Extreme Cold Weather#proce-
dures, it may be flooded. To clear any excess fuel, press
and hold the brake pedal, push the accelerator pedal all
the way to the floor and hold it, then press and release the
ENGINE START/STOP button once. The starter motor
will engage automatically, run for 10 seconds, and then
disengage. Once this occurs, release the accelerator pedal
and the brake pedal, wait 10 to 15 seconds, then repeat
the “Normal Starting” procedure.
