When frequent transmission shifting occurs (such as when
operating the vehicle under heavy loading conditions, in
hilly terrain, traveling into strong head winds, or while
towing a heavy trailer), use the AutoStick shift control (if
equipped; refer to AutoStick in this section for further
information) to select a lower gear. Under these conditions,
using a lower gear will improve performance and extend
transmission life by reducing excessive shifting and heat
buildup.
During extremely cold temperatures (-22°F [-30°C] or be-
low), transmission operation may be modified depending
on engine and transmission temperature as well as vehicle
speed. Normal operation will resume once the transmis-
sion temperature has risen to a suitable level.
SPORT (S) — If Equipped
This mode alters the transmission’s automatic shift sched-
ule for sportier driving. Upshift speeds are increased to
make full use of available engine power. To access SPORT
mode, push down on the gear selector and rotate it fully
clockwise, or push the SPORT button in the center stack.
LOW (L) — If Equipped
Use this range for engine braking when descending very
steep grades. In this range, the transmission will downshiftfor increased engine braking. To access the LOW position,
push down on the gear selector and rotate it fully clock-
wise.
Transmission Limp Home Mode
Transmission function is monitored electronically for ab-
normal conditions. If a condition is detected that could
result in transmission damage, Transmission Limp Home
Mode is activated. In this mode, the transmission may
operate only in certain gears, or may not shift at all. Vehicle
performance may be severely degraded and the engine
may stall. In some situations, the transmission may not
re-engage if the engine is turned off and restarted. The
Malfunction Indicator Light (MIL) may be illuminated. A
message in the instrument cluster will inform the driver of
the more serious conditions, and indicate what actions may
be necessary.
In the event of a momentary problem, the transmission can
be reset to regain all forward gears by performing the
following steps:
NOTE:
In cases where the instrument cluster message
indicates the transmission may not re-engage after engine
shutdown, perform this procedure only in a desired loca-
tion (preferably, at your authorized dealer).
308 STARTING AND OPERATING

nut torque refer to “Torque Specifications” in this
section. If in doubt about the correct tightness, have
them checked with a torque wrench by your autho-
rized dealer or at a service station.
11. Stow the jack, tools and flat tire. Make sure the base of the jack faces the front of the vehicle before tightening
down the fastener.
WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could endanger the occupants of the vehicle.
Always stow the jack parts and the spare tire in the
places provided. Have the deflated (flat) tire repaired
or replaced immediately.
Road Tire Installation
1. Mount the road tire on the axle.
2. Install the remaining lug nuts with the cone shaped endof the nut toward the wheel. Lightly tighten the lug
nuts.
WARNING!
To avoid the risk of forcing the vehicle off the jack, do
not tighten the lug 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. Refer to “Torque Specifications” in this section for proper lug nut torque.
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 PROCEDURES
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.
