1. Check the other vehicle. It must
have a 12-volt battery with a
negative ground system.
Notice: If the other vehicle's
system is not a 12-volt system
with a negative ground, both
vehicles can be damaged. Only
use vehicles with 12-volt systems
with negative grounds to jump
start your vehicle.
2. Position the two vehicles so that
they are not touching.
3. Set the parking brake firmly and
put the shift lever in P (Park).
See Shifting Into Park on
page 8‑24.
Notice: If you leave the radio or
other accessories on during the
jump starting procedure, they
could be damaged. The repairs
would not be covered by the
warranty. Always turn off the
radio and other accessories when
jump starting the vehicle.
4. Turn the ignition to LOCK/OFF
and switch off all lights and
accessories in both vehicles,
except the hazard warning
flashers if needed.
