Fuel Economy Mode
The vehicle may have a Fuel
Economy Mode. When engaged,
fuel economy mode can improve the
vehicle's fuel economy.
Press the“eco”(economy) button by
the shift lever to turn this feature on
or off. The “eco”light in the
instrument cluster will come on
when engaged. See Fuel Economy
Light
on page 4‑23. For vehicles with a Driver Information Center
(DIC) an
“ECO Mode On” message
displays. See Fuel System
Messages
on page 4‑32for more
information.
When Fuel Economy Mode is on:
.The transmission will upshift
sooner and downshift later.
.The torque converter clutch will
apply sooner and stay on longer.
.The gas pedal will be less
sensitive.
.The vehicle's computer will more
aggressively shut off fuel to the
engine under deceleration.
.The engine idle speed will be
lower.
.Driving performance is more
conservative.
Drive Systems
All-Wheel Drive
With this feature, engine power is
always sent to all four wheels. It is
fully automatic, and adjusts itself as
needed for road conditions.
When using a compact spare tire on
an AWD vehicle, the system
automatically detects the compact
spare and disables AWD. To restore
AWD operation and prevent
excessive wear on system, replace
the compact spare with a full-size
tire as soon as possible. See
Compact Spare Tire
on page 9‑76for more information.

Driving and Operating 8-45
5(On/Off):Press to turn the
cruise control system on and off.
\(Cancel): Press to cancel cruise
control without erasing the set
speed from memory.
RES/+ (Resume/Accel): Move the
thumbwheel up to resume a set
speed or to accelerate to a higher
speed.
SET/− (Set/Coast): Press the
thumbwheel to set a speed or move
the thumbwheel down to decrease
the speed. To set a speed:
1. Press
5.
2. Get to the speed desired.
3. Press the thumbwheel and release it. The desired set speed
briefly appears in the instrument
panel cluster.
4. Take your foot off the accelerator pedal.
When the brakes are applied, the
cruise control shuts off.
Resuming a Set Speed
If the brakes are applied while the
cruise control is at a set speed, the
cruise control disengages. But it
does not need to be reset.
Once the vehicle reaches about
40 km/h (25 mph) or more, move the
thumbwheel up toward RES/+
briefly. The vehicle returns to the
speed selected previously and stays
there. Increasing Speed While Using
Cruise Control
There are two ways to go to a
higher speed. Disengage the cruise
control, but do not turn it off.
.If the cruise control system is
already engaged, move the
thumbwheel up toward RES/+
and hold it until the vehicle
accelerates to the desired
speed, and then release it.
.To increase the speed in small
amounts, move the thumbwheel
up toward RES/+ briefly and
then release it. Each time this is
done, the vehicle goes about
1.6 km/h (1 mph) faster.

Tire Pressure Monitor
Operation
This vehicle may have a Tire
Pressure Monitor System (TPMS).
The TPMS is designed to warn the
driver when a low tire pressure
condition exists. TPMS sensors are
mounted onto each tire and wheel
assembly, excluding the spare tire
and wheel assembly. The TPMS
sensors monitor the air pressure in
the vehicle's tires and transmit the
tire pressure readings to a receiver
located in the vehicle.
When a low tire pressure condition
is detected, the TPMS illuminates
the low tire pressure warning light
located on the instrument panel
cluster. If the warning light comes
on, stop as soon as possible andinflate the tires to the recommended
pressure shown on the tire loading
information label. See
Vehicle Load
Limits on page 8‑22.
At the same time a message to
check the pressure in a specific tire
appears on the Driver Information
Center (DIC) display. The low tire
pressure warning light and the DIC
warning message come on at each
ignition cycle until the tires are
inflated to the correct inflation
pressure. Using the DIC, tire
pressure levels can be viewed by
the driver. For additional information
and details about the DIC operation
and displays see Driver Information
Center (DIC) on page 4‑25.
The low tire pressure warning light
may come on in cool weather when
the vehicle is first started, and then
turn off as you start to drive. This
could be an early indicator that the
air pressure in the tire(s) are getting
low and need to be inflated to the
proper pressure. A Tire and Loading Information
label, attached to your vehicle,
shows the size of your vehicle's
original equipment tires and the
correct inflation pressure for your
vehicle's tires when they are cold.
See
Vehicle Load Limits
on
page 8‑22, for an example of the
Tire and Loading Information label
and its location on your vehicle.
Also see Tire Pressure
on
page 9‑52.
Your vehicle's TPMS can warn you
about a low tire pressure condition
but it does not replace normal tire
maintenance. See Tire Inspection
on page 9‑58,Tire Rotationon
page 9‑58and Tires on page 9‑45.
Notice: Liquid tire sealants could
damage the Tire Pressure Monitor
System (TPMS) sensors. Sensor
damage caused by using a tire
sealant is not covered by your
warranty. Do not use liquid tire
sealants.
