a connected audio device, either press the “AUX” button on the radio faceplate or press the VR button and say
USB
orSwitch to USB. Once in the iPod/USB/MP3
control mode, audio tracks (if available from audio
device) start playing over the vehicle’s audio system.
Play Mode
When switched to iPod/USB/MP3 control mode, the
iPod or external USB device automatically starts Play
mode. In Play mode, the following buttons on the radio
faceplate may be used to control the iPod or external
USB device and display data:
•Use the TUNE control knob to select the next or
previous track.
•Turning it clockwise (forward) by one click, while
playing a track, skips to the next track or press the
VR button and say Next Track.
•Turning it counterclockwise (backward) by one
click, will jump to the previous track in the list or
press the VR button and say Previous Track

UNDERSTANDING YOUR INSTRUMENT PANEL 355

•Press the ENGINE START/STOP button a second time
to change the ignition switch to the RUN position
(EVIC displays “IGNITION MODE RUN”),
•Press the ENGINE START/STOP button a third time
to return the ignition switch to the OFF position (EVIC
displays “IGNITION MODE OFF”).
Extreme Cold Weather (Below –20°F Or29°C)
To ensure reliable starting at these temperatures, use of
an externally powered electric engine block heater (avail-
able from your authorized dealer) is recommended.
If Engine Fails To Start
WARNING!
•Never pour fuel or other flammable liquids into
the throttle body air inlet opening in an attempt to
start the vehicle. This could result in a flash fire
causing serious personal injury.
•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 improp-
erly. Refer to “Jump Starting” in “What To Do In
Emergencies” for further information.

STARTING AND OPERATING 417

WARNING!
To avoid the risk of forcing the vehicle off the jack,
do not tighten the wheel nuts fully until the vehicle
has been lowered. Failure to follow this warning may
result in personal injury.
3. Lower the vehicle to the ground by turning the jack
handle counterclockwise.
4. Finish tightening the lug nuts. Push down on the
wrench while at the end of the handle for increased
leverage. Tighten the lug nuts in a star pattern until each
nut has been tightened twice. The correct tightness of
each lug nut is 110 ft/lbs (150 N·m). If in doubt about the
correct tightness, have them checked with a torque
wrench by your authorized dealer or service station. 5. After 25 miles (40 km) check the lug nut torque with a
torque wrench to ensure that all lug nuts are properly
seated against the wheel.
JUMP-STARTING
If your vehicle has a discharged battery it can be jump-
started using a set of jumper cables and a battery in
another vehicle or by using a portable battery booster
pack. Jump-starting can be dangerous if done improperly
so please follow the procedures in this section carefully.
NOTE:
When using a portable battery booster pack
follow the manufacturer’s operating instructions and
precautions.

WHAT TO DO IN EMERGENCIES 559

WARNING!
•Take care to avoid the radiator cooling fan when-
ever the hood is raised. It can start anytime the
ignition switch is on. You can be injured by
moving fan blades.
•Remove any metal jewelry such as watch bands or
bracelets that might make an inadvertent electrical
contact. You could be seriously injured.
•Batteries contain sulfuric acid that can burn your
skin or eyes and generate hydrogen gas which is
flammable and explosive. Keep open flames or
sparks away from the battery.
1. Set the parking brake, shift the automatic transmission
into PARK and turn the ignition to LOCK.
2. Turn off the heater, radio, and all unnecessary electri-
cal accessories. 3. Remove the protective cover over the remote positive
(+)
battery post. Pull upward on the cover to remove it.
4. If using another vehicle to jump-start the battery, park
the vehicle within the jumper cables reach, set the
parking brake and make sure the ignition is OFF.
WARNING!
Do not allow vehicles to touch each other as this
could establish a ground connection and personal
injury could result.
Jump-Starting Procedure
WARNING!
Failure to follow this procedure could result in per-
sonal injury or property damage due to battery ex-
plosion.

WHAT TO DO IN EMERGENCIES 561

CAUTION!
Failure to follow these procedures could result in
damage to the charging system of the booster vehicle
or the discharged vehicle.
1. Connect the positive (+)end of the jumper cable to the
remote positive (+)post of the discharged vehicle.
2. Connect the opposite end of the positive (+)jumper
cable to the positive (+)post of the booster battery.
3. Connect the negative end (-)of the jumper cable to the
negative (-)post of the booster battery.
4. Connect the opposite end of the negative (-)jumper
cable to the remote negative (-)post of the vehicle with
the discharged battery.
WARNING!
Do not connect the cable to the negative post (-) of the
discharged battery. The resulting electrical spark
could cause the battery to explode and could result in
personal injury.
5. Start the engine in the vehicle that has the booster
battery, let the engine idle a few minutes, and then start
the engine in the vehicle with the discharged battery.
Once the engine is started, remove the jumper cables in
the reverse sequence:
6. Disconnect the negative (-)jumper cable from the
remote negative (-)post of the discharged vehicle.
7. Disconnect the negative end (-)of the jumper cable
from the negative (-)post of the booster battery.
8. Disconnect the opposite end of the positive (+)jumper
cable from the positive (+)post of the booster battery.
562 WHAT TO DO IN EMERGENCIES

9. Disconnect the positive(+)end of the jumper cable
from the remote positive (+)post of the discharged
vehicle.
10. Reinstall the protective cover over the remote posi-
tive (+)battery post of the discharged vehicle.
If frequent jump-starting is required to start your vehicle
you should have the battery and charging system in-
spected at your authorized dealer.
CAUTION!
Accessories that can be plugged into the vehicle
power outlets draw power from the vehicle’s battery,
even when not in use (i.e., cellular phones, etc.).
Eventually, if plugged in long enough, the vehicle’s
battery will discharge sufficiently to degrade battery
life and/or prevent the engine from starting.
FREEING A STUCK VEHICLE
If the vehicle becomes stuck in snow, sand or mud, it can
often be moved by a rocking motion. Move the shift lever
rhythmically between DRIVE and REVERSE while ap-
plying slight pressure to the accelerator. In general, the
least amount of accelerator pedal pressure to maintain
the rocking motion without spinning the wheels or racing
the engine is most effective.
CAUTION!
Racing the engine or spinning the wheels may lead to
transmission overheating and failure. Allow the en-
gine to idle with the shift lever in NEUTRAL for at
least one minute after every five rocking-motion
cycles. This will minimize overheating and reduce
the risk of transmission failure during prolonged
efforts to free a stuck vehicle.6
