158 STARTING AND OPERATING
You can switch between DRIVE and ERS mode at
any vehicle speed. When the gear selector is in the
DRIVE position, the transmission will operate
automatically, shifting between all available gears.
Tapping the GEAR "-" switch will activate ERS
mode, display the current gear in the instrument
cluster, and set that gear as the top available gear.
Once in ERS mode, tapping the GEAR "–" or GEAR
"+" switch will change the top available gear.
Electronic Range Select
1 — GEAR "+" Switch
2 — GEAR "–" Switch
To exit ERS mode, simply push and hold the GEAR
"+" switch until the gear limit display disappears
from the instrument cluster.
WARNING!
Do not downshift for additional engine braking
on a slippery surface. The drive wheels could
lose their grip and the vehicle could skid,
causing a collision or personal injury.

NOTE:
To select the proper gear position for maximum
deceleration (engine braking), simply push and
hold the GEAR "–" switch. The transmission will
shift to the range from which the vehicle can best
be slowed down.
CAUTION!
When using ERS for engine braking while
descending steep grades, be careful not to
overspeed the engine. Apply the brakes as
needed to prevent engine overspeed.
Overdrive Operation
The automatic transmission includes an
electronically controlled Overdrive (FIFTH and
SIXTH gears). The transmission will automatically
shift into Overdrive if the following conditions are
present:
The gear selector is in the DRIVE position.

5 6 D
The transmission fluid has reached an

adequate temperature.
The engine coolant has reached an adequate

temperature.
The vehicle speed is sufficiently high.

The driver is not heavily pressing the

accelerator.
When To Use TOW/HAUL Mode
When driving in hilly areas, towing a trailer, carrying
a heavy load, etc., and frequent transmission
shifting occurs, push the TOW/HAUL switch to
activate TOW/HAUL mode. This will improve
performance and reduce the potential for
transmission overheating or failure due to
excessive shifting. When operating in TOW/HAUL
mode, transmission upshifts are delayed, and the
transmission will automatically downshift (for
engine braking) when the throttle is closed and/or
during steady braking maneuvers.
