Driving up or down hills

[Driving uphill
-Before starting off, check if it is
possible to drive uphill.
-Drive as straight as possible.

[Driving downhill
-Do not change gear while driving
downhill. Select gear before driving
downhill.
-Drive slowly using engine braking
while driving downhill.
-Drive straight as possible.
WARNING
Exercise extreme caution driving up or
down steep hills. The vehicle may flip
over depending on the grade, terrain,
water and mud conditions.
WARNING
Do not drive across the contour of steep
hills. A slight change in the wheel angle
can destabilize the vehicle, or a stable
vehicle may lose stability if the vehicle
stops its forward motion. Your vehicle
may roll over and lead to a serious injury
or death.
Emergency Precautions
Tires
When replacing tires, be sure to equip
all four tires with the same size, type,
tread pattern, brand and load-carrying
capacity.
WARNING
Do not use tire and wheel with different
size and type from the one originally
installed on your vehicle. It can affect
the safety and performance of your
vehicle, which could lead to steering
failure or rollover causing serious injury.
In an emergency situation, a compact
spare tire may be used. But, do not use
the compact spare tire continuously.
Repair or replace the original tire as
soon as possible to avoid failure of the
differential or AWD system.

Driving Your Vehicle
WARNING
ORS061054L
Never start or run the engine while
an AWD vehicle is raised on a jack.
The vehicle can slip or roll off of a jack
causing serious injury or death to you or
those nearby.
Towing
AWD vehicles must be towed with
a wheel lift and dollies or flatbed
equipment with all the wheels off
the ground. For more details, refer to
"Towing" section in chapter 8.
Vehicle inspection

[If the vehicle needs to be operated on
a vehicle lift do not attempt to stop
any of the four wheels from turning.
This could damage the AWD system.

[Never engage the parking brake while
running the engine on a car lift. This
may damage the AWD system.
Dynamometer testing
An AWD vehicle must be tested on a
special four wheel chassis dynamometer.
ORS061055LA : Roll tester (Speedometer),
B : Temporary free roller
An AWD vehicle should not be tested
on a 2WD roll tester. If a 2WD roll tester
must be used, perform the following
procedure:
1. Check the tire pressures
recommended for your vehicle.
2. Place the rear wheels on the roll tester
for a speedometer test as shown in
the illustration.
3. Release the parking brake.
4. Place the front wheels on the
temporary free roller as shown in the
illustration.
WARNING
Keep away from the front of the vehicle
while the vehicle is in gear on the
dynamometer. The vehicle can jump
forward and cause serious injury or
death.

System Malfunction
OJWEV061048L
Check Electronic Suspension
When Electronically Controlled
Suspension with Road Preview is not
working properly, this warning message
will appear on the cluster LCD display. If
this occurs, have the system inspected
by an authorized retailer of Genesis
Branded products.
NOTICE
If the battery level is high or low,
Electronically Controlled Suspension
with Road Preview may not work
temporarily to protect the system. If this
occurs, ‘Check Electronic Suspension’
warning message will appear.
Limitations of the System
Electronically Controlled Suspension
with Road Preview always operates
while driving according to the vehicle’s
movement, and the preview function
starts to work when the front view
camera detects road conditions such as
speed bumps. Therefore, the preview
function is limited when there is an
extreme condition that the front view
camera may not work normally. In this
case, the electronic control suspension
function operates without the preview
function in accordance with vehicle
movement.

Multi-Chamber Air Suspension
Malfunction
OJWEV061048L
This message is displayed when there is
a malfunction with the Multi-chamber
air suspension system. Have the vehicle
inspected by an authorized retailer of
Genesis Branded products.
CAUTION

[When adjusting vehicle height, check
if there are any obstacles below or
above the vehicle.

[If air inside the suspension is
discharged, a warning message
will be displayed. If so, stop driving
and use a towing vehicle. Since
the vehicle height will be very low,
projections on the road may damage
the vehicle. See ‘Towing when the
air suspension malfunctions’ before
towing the vehicle.
Information

[Operating the air suspension may
cause a little noise when charging and
discharging the air.

[Adjusted vehicle height may vary
depending on the temperature and
surrounding environment.

[When the suspension warning message
is displayed, the system enables safe
mode to prevent secondary failure
and the vehicle performance may be
displayed differently.

[When the vehicle is parked on a slope,
or when the vehicle is in unstable
condition due to sudden acceleration,
deceleration or steering, vehicle height
adjustment becomes temporarily
disabled. If the vehicle escapes from
such dangerous situation, vehicle height
adjustment is enabled again.

[When the vehicle is lifted up with a
lift or jack, height adjustment may be
disabled to protect the system. If the
vehicle engine is started or you start
driving, the function is enabled again.

[Leaving the vehicle parked for long
time may lower the vehicle height. The
vehicle height returns to its original
position when the engine is started.

[If the battery is either overcharged or
discharged, vehicle height adjustment
is disabled to protect the system and a
temporary warning message may be
displayed.

[If the vehicle height adjustment is
operated repeatedly, the function may
be temporarily disabled due to the
overheated compressor. It is to prevent
the breakdown of related parts.
