PERFORMANCE & MAINTENANCE
Malfunction Indicator Lamp
(Service Engine Soon Lamp)
This instrument panel cluster lamp
illuminates under a variety of conditions
when the On-Board Diagnostics II (OBD
II) system detects a malfunction in the
vehicle’s emission controls.
If the Malfunction Indicator Lamp
is lit steadily, check the gas cap to
ensure it is present and securely
fastened
• Turn the cap clockwise until a ratch-
eting sound is heard, signaling that it
is secure.
• If this is the cause of the condition, a
few driving trips with the cap installed
properly should turn the light off.
See Section 3 of your Owner Manual.
Electronically Controlled
Air Suspension (if equipped)
Occasional whirring and/or hissing
sound under the rear of the vehicle
• This sound indicates that the sys-
tem’s air compressor is operating to
provide a level ride height, and is
normal.
See Section 4 of your Owner Manual.
Luggage Carrier (if equipped)
Slide the crossrails to desired
position
1. Pull up the lever on each side of the
crossrail. This will release the cross-
rail and allow you to slide it.
2. When the crossrail is where you want
it, press down on the levers to lock it
in place.
Reduce wind noise when the roof
luggage carrier is not in use
• Position the rear crossrail at the
rearmost position and the front
crossrail above the rearmost portion
of the rear door opening (above the
C-pillar).
See Section 2 of your Owner Manual.
Note:Never carry anything on the vehi-
cle roof that is longer or wider than the
luggage carrier itself. (Examples: ply-
wood, paneling, a mattress.) The load
could be violently torn off, causing you
or others to have a collision.
Loading cargo that weighs more than
220 pounds (100 kg) on the luggage
carrier may damage your vehicle.

Tire Pressure Monitor
The Tire Pressure Monitor alerts you
when a significant reduction in pressure
occurs in one or more of your vehicle’s
tires by illuminating the (Low Tire
Pressure) warning light on the instru-
ment panel cluster. The low tire pressure
warning light will remain on until you
correct the tire pressure. A CHECK TIRE
PRESSURE message will also appear
on the DIC.
Correcting the Tire Pressure
When the low tire pressure warning light
illuminates, you must inflate the tire to
the proper tire pressure (just as you
must refuel the vehicle when the low
fuel warning light illuminates). The Tire
and Loading Information label shows the
correct tire pressure for the tires when
they’re cold. “Cold” means your vehicle
has been sitting for at least three hours
or driven no more than one mile.
You can temporarily clear the DIC
message by acknowledging it with your
DIC controls. However, at the next
vehicle start-up, the DIC message will
reappear if the tire pressure has not
been corrected.
During cooler conditions, the low tire
pressure warning light may appear when
the vehicle is first started and then turn
off as you start to drive. This could be
an early indicator that your tire pres-
sures are getting low and the tires need
to be inflated to the proper pressure.
See Section 5 of your Owner Manual.
Note: The Tire Pressure Monitor can
alert you about low tire pressure, but it
doesn’t replace normal monthly tire
maintenance.
Tire Inflator Kit (if equipped)
Your vehicle may not have a spare tire
or a jack. In case of a flat tire, a tire
inflator kit is provided to seal small
punctures in the tread area of the tire.
The kit is located in the storage com-
partment in the floor of the rear cargo
area. Refer to the tire inflator kit instruc-
tions for complete operating information.
See Section 5 of your Owner Manual.
