2014 JEEP GRAND CHEROKEE suspension

NOTE:Any chassis/suspension or tire size modifications
to the vehicle will effect the performance of the Adaptive
Cruise Control.
Activating Adaptive Cruise Control (ACC)
You can only engage ACC if the vehicle speed is above
0 mph (0 km/h).
The minimum Set Speed for the ACC system is 20 mph
(32 km/h).
When the system is turned on and in the READY state,
the Electronic Vehicle Information Center (EVIC) dis-
plays “ACC Ready.”
When the system is OFF, the EVIC displays “Adaptive
Cruise Control (ACC) Off.” NOTE:
You cannot enable ACC under the following
conditions:
• When in Four-Wheel Drive Low.
• When you apply the brakes.
• When the parking brake is set.
• When the automatic transmission is in PARK, RE-
VERSE or NEUTRAL.
• When the Vehicle speed is outside of the speed range.
• When the brakes are overheated.
• When the driver door is open.
• When the driver seat belt is unbuckled.
200 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

SELEC-TRAC® — IF EQUIPPED
Description
Selec-Trac® combines the capabilities of the vehicle con-
trol systems, along with driver input, to provide the best
performance for all terrains.Selec-Trac® consists of the following positions:
•
Sport – Dry weather, on-road calibration. Performance
based tuning that provides a rear wheel drive feel but
with improved handling and acceleration over a two-
wheel drive vehicle. The customer has the option of
going to partial ESC. The active suspension system
will be in Semi Firm mode, and a green flag will light
up in the instrument cluster. The transmission will
provide a more aggressive shifting pattern (Refer to
“Paddle Shift Mode” in “Starting And Operating” for
further information). This feature will reset to AUTO
on an ignition cycle.
• Snow – Tuning set for additional stability in inclement
weather. Use on and off road on loose traction surfaces
such as snow. When in Snow mode (depending on
certain operating conditions), the transmission may
use second gear (rather than first gear) during
launches, to minimize wheel slippage.

STARTING AND OPERATING 409

•Auto– Fully automatic full time four-wheel drive
operation can be used on and off road. Balances traction
with seamless steering feel to provide improved han-
dling and acceleration over two-wheel drive vehicles.
The active suspension system will be in Touring Mode.
• Track –Track road calibration for use on high traction
surfaces. Driveline is maximized for traction. Some
binding may be felt on less forgiving surfaces. The
electronic brake controls are set to Partial OFF to limit
traction control management of throttle and wheel spin.
• The transmission will be in SPORT mode and pro-
vide a more aggressive shifting pattern. Refer to
“Paddle Shift Mode” in “Starting And Operating”
for further information.
• The customer has the option of going to FULL OFF
with no interaction from the ESC System. The active
suspension system will be in Full Firm mode.
• This feature will reset to AUTO on an ignition cycle. •
To w – Use this mode for towing. Vehicle suspension
will go to Firm mode. Trailer sway control is enabled
in the ESC system. The terrain switch will remain in
this position through an ignition cycle until the cus-
tomer cycles into another position.
Active Damping System
This vehicle is equipped with an electronic controlled
damping system. This system reduces body roll and pitch
in many driving situations including cornering, accelera-
tion and braking. There are 3 modes:
• Touring Mode (Available in terrain positions AUTO
and SNOW) — Used during highway speeds where a
touring suspension feel is desired.
• Firm Mode
(Available in terrain positions SPORT and
TOW) — Provides a firm suspension for better handling.
• Full Firm (Available in TRACK mode) — Provides a
full firm suspension for an aggressive track experience.
410 STARTING AND OPERATING

Gross Vehicle Weight Rating (GVWR)
The GVWR is the total permissible weight of your vehicle
including driver, passengers, vehicle, options and cargo.
The label also specifies maximum capacities of front and
rear axle systems (GAWR). Total load must be limited so
GVWR and front and rear GAWR are not exceeded.
Payload
The payload of a vehicle is defined as the allowable load
weight a truck can carry, including the weight of the
driver, all passengers, options and cargo.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum permissible load on the front
and rear axles. The load must be distributed in the cargo
area so that the GAWR of each axle is not exceeded.Each axle GAWR is determined by the components in the
system with the lowest load carrying capacity (axle,
springs, tires or wheels). Heavier axles or suspension
components sometimes specified by purchasers for in-
creased durability does not necessarily increase the vehi-
cle’s GVWR.
Tire Size
The tire size on the Vehicle Certification Label represents
the actual tire size on your vehicle. Replacement tires
must be equal to the load capacity of this tire size.
Rim Size
This is the rim size that is appropriate for the tire size listed.
Inflation Pressure
This is the cold tire inflation pressure for your vehicle for
all loading conditions up to full GAWR.
468 STARTING AND OPERATING

CAUTION!(Continued)
•Then, during the first 500 miles (805 km) that a
trailer is towed, do not drive over 50 mph (80 km/h)
and do not make starts at full throttle. This helps
the engine and other parts of the vehicle wear in at
the heavier loads.
Perform the maintenance listed in the “Maintenance
Schedule.” Refer to “Maintenance Schedule” for the
proper maintenance intervals. When towing a trailer,
never exceed the GAWR or GCWR ratings.
WARNING!
Improper towing can lead to a collision. Follow these
guidelines to make your trailer towing as safe as
possible:
• Make certain that the load is secured in the trailer
and will not shift during travel. When trailering
cargo that is not fully secured, dynamic load shifts
can occur that may be difficult for the driver to
control. You could lose control of your vehicle and
have a collision.
• When hauling cargo or towing a trailer, do not
overload your vehicle or trailer. Overloading can
cause a loss of control, poor performance or dam-
age to brakes, axle, engine, transmission, steering,
suspension, chassis structure or tires.
